Bleed Brake Master Cylinder While On Car WITHOUT Bench Bleeding Done Alone-No Partner!

So I was flushing the brakes after changing my pads and rotors. I figured it was time for new brake fluid. But I screwed up! On the last brake I was flushing, I forgot to keep the master brake cylinder reservoir topped off! In fact, I let the brake master cylinder run dry which meant I introduced air into the brake master cylinder. This traditionally would require uninstalling the brake master cylinder, connecting hoses to its bottom drain port lines and running those to the reservoir with the master brake cylinder clamped in a vice and then pumping in the piston with a screw driver to cause the brake fluid to move out of the brake master cylinder and into the reservoir which would flush out all air bubbles over time - this process being called a bench bleed to remove the air from the master cylinder. However, after extensive research, I discovered a little known method for bleeding the brake master cylinder while it is still on car and better yet, without having to remove ANY brake lines or hoses! You don't even need a brake master cylinder bleeder kit! All you need is 10ft of vinyl hose! You simply connect the hose up to the front left caliper bleeder nipple and then run the hose into the brake master cylinder fluid reservoir. Then you top off the reservoir and tape the hose in place if needed to ensure it doesn't come out. Now, you pump your brakes while making sure to keep the brake master cylinder reservoir topped off with fluid so you don't introduce more air into the system. Then, after pumping the brakes (never pumping the brake petal all the way to the ground but only 2/3rd of the way tops else you risk breaking the master cylinder - or so I read) you eventually see all of the air gone from your clear vinyl hose and just see fluid running through! Then you know you have successfully removed all air from the master cylinder. Well you need to keep going even after that just about 50 or so more pumps. The more pumps the better as you are enabling the master cylinder trapped air pockets to bubble and work their way out of the master cylinder over repeated patting of the brake petal over time. After this process is done, flush all the brakes at each of the 3 remaining wheels beginning with the rear right wheel, then the rear left wheel, then the front right wheel. You can do this with any brake bleeding method - gravity, partner, vacuum pump, pressure bleeding, etc. Once all brakes are fully bled, you should be back in business! My car brakes were PERFECT after this process. Also, as a side note, when flushing the fluid in the first step from the caliper and back into the reservoir, I put a coffee strainer on the end of the hose to ensure no particles got into the reservoir. Also, the fluid I was cycling back into the reservoir was new fluid as I had already flushed all my lines with new fluid 2 days prior. So the fluid was very clean still.

I am sorry but would it not be more simple to remove your tires remove your brake pads use a c-clamp to compress your brake calipers therefore the system remains closed ,and any air that may have been in the system is expelled . replace your pads,replace your calipers your tires and lugs,check your fluid level.and reservoir cap for tightness pump your breaks until tight. your done.by using a c-clamp to compress the calipers. no need to bleed.same applies to flushing the system , i am sure you will figure it out from here.have a nice day and don't work so hard.

@ToolinAround 6 лет назад

artbyrobot quick bleeder screws will save you a majot headache. You open the bleeder and pump the brakes until the air is out. They have a built in check valve and won't allow air to come back into the line

@johnpaulgarrett1 4 года назад

The reason why your brakes were still squishy after you bled the master cylinder is because earlier in the day when you were bleeding the last brake and accidentally ran out of fluid in the reservoir you introduced air into BOTH the master cylinder and into the rear wheel's brake line. Therefore you needed to bleed air out of BOTH the master cylinder and the brake line leading to the rear wheel. You could have remedied this problem by running a long hose from the rear brake to the master cylinder to bleed both the rear brake line and the master cylinder at the same time. If you didn't have a long enough tube to reach from rear of car to master cylinder you could take a short tube and attach it to rear brake bleeder and run it UP into a liquid filled container higher than the brake bleeder. Put the tube end into the liquid in this container. Most people put this container BELOW the bleeder height sometimes requiring around 40 stabs of the brake pedal to eliminate air bubbles. If you put the container ABOVE the bleeder height you will find that it takes 1-5 pumps to bleed the line completely. Please note that this second method will bleed the brake line only. Make sure you bleed the master cylinder by running the tube from either one of your front wheels to the master cylinder reservoir.-MARYLAND MOBILE MECHANIC-Johnpaul.

@wildcatwildcat7944 4 года назад

Thanks for taking the time to film and post this. Theoretically I think that you were actually still only bleeding the front left line and in the process getting the air that you may have introduced into the master. The main thing that you accomplished with that loop was to recycle the fluid so that you didn't have to keep refilling or buying more fluid. For anyone that is thinking of doing this, you should make sure to flush all your lines first to get all the old fluid out so that you don't recycle the old fluid back into the master. The coffee filter was definitely a good thing to catch any debris. As you found that once you got that large quantity of air out, the was still air in the other lines and you still needed go back and re-bleed at each wheel, starting with the farthest from the master (back right). The other potential issue is that the air in the "closed loop" line was getting fed back into the master, so if it was a true closed loop the air wouldn't actually escape, so you need to make sure that the looped line is positioned in the master in such a way that the air can escape and doesn't get trapped, thus defeating the purpose. In theory, you could actually create that closed loop at each wheel and bleed the whole system that way, however again I stress that you should probably flush the old fluid first and definitely use a filter.

@miloo318 2 года назад

I watched the entire video... You are aware he was flushing his brake system beforehand and was on the drivers side "the last wheel" when he ran the cylinder dry, right? That would mean the system has all new fluid right? And wasnt the large quantity of air nothing more than air that is in the hose when you buy it off the shelf? What is the "closed loop" you are referring too...The hose he bought or something in the brake line system?

Great video... I had the exact same problem and searched for a solution. Most suggestions were to remove the master cylinder to resolve the trapped air issue. ABSOLUTE NONSENSE and obviously the dealerships want you to believe this so you won't try it yourself. This man had the right idea with bleeding the MC from the nearest hub, but an even easier option, rather than looping back to the reservoir, is to just let the fluid run into a bottle like you would normally do when bleeding and continually top up the MC. A couple of depressions of the brake pedal and gravity will do the rest for you. You might need to bleed the other brakes in the normal order to make sure all air is expelled but this method most DEFINITELY WORKS!

@dntlss 5 месяцев назад

Heck there are people out there that install master cylinders dry and just get the air out by bleeding the wheels and it works fine,might take a little longer.

I just wanted to leave a quick testimonial on how this video saved me in a pinch. I made the same move when changing just the P/S caliper of my 2008 Impala - I let all the fluid drain out. I couldn't get system pressure, and I thought I was screwed! While watching this vid, I walked to Home Depot and bought 20 ft. of 5/8" hose for $8 (cut to length). It took ALOT of pumping and patience, but it worked like a charm! Thanks, saved me alot of aggravation, time, and money.

@kellykeys6092 4 года назад

This method is more effective if you partially or fully fill the vinyl tube with fresh brake fluid first and make sure the tube is raised so that any air will rise away from the nipple. Otherwise, as you let off the brake peddle, air can be sucked back into the brake caliper. Just thought I'd mention that. . .

@jackwade793 4 месяца назад

If you pump the brakes and watch the air going back into the master cylinder. You are correct. When you let off the pedal. All that air can be sucked back into the master cylinder. However…….if you pump the fluid and watch the air go into the master cylinder. You hold the pad Al down for about 5-10 seconds. This will allow time for the air to rise to the top of the master cylinder and pop the bubble. I have bench bled the master cylinder only…..on the car by itself. On an older car, with the ability to see what was going on. I could see down to the bottom of the reservoir. The air bubbles need time to rise and pop. Letting off the pedal too soon doesn’t allow for that. Also…….the fluid should be crystal clear if you can see it. When it is not. It means you have allowed moisture or old fluid or solvent contaminants into the system. When I cleaned my whole system. I flushed it out with brake clean and then compressed air to get rid on it. I forgot to compresses out the master cylinder. When the new fluid was put in. It contaminated with the solvent. I took apart the master cylinder and rebuilt it. Fluid has to be transparent

@xx3astmanxx928 5 лет назад

I was able to restore full hydraulic pressure to my brake system because of this video thank u for making it! I already knew I wouldn't have to replace my master, as the reservoir never fully depleted, so no air got into the master cylinder. All I had to do was get the hose (5/16 OD 3/16 ID), and ran it to the baffle in the reservoir. My brother pumped the brakes while I slowly added a small amount of fluid, and amazingly the fluid coming from the reservoir was already immaculate, to the point that once the process was complete I simply drained the hose back into my brake fluid container. Thinking about doing the others just to be certain there's no air in the system whatsoever but I'll have to wait till the weekend lol

@johnkirby6700 4 года назад

Bad idea. You should never reuse brake fluid. It may look clean but it definitely has absorbed moisture from the air and small particles are in it from the brake system.It's cheap, so toss the old fluid.

@michaelmclernon4929 6 лет назад

Kudos ! A clever workaround to removing master cylinder. Just a thought, if there is access you can do a so-called bench bleed on the car, using the same bench bleed tubes as you would on your workbench, or do it by loosening the tubing connections to the M/C with the help of an assistant on the pedal, and lots of rags wrapped around the fitting, but being careful to not release the pedal until the fitting is closed. Of course you would do each half of the M/C separately. 4 or 5 strokes ought to do it.Also you are the first I have seen on RU-vid that shows any concern for introducing debris into the M/C.The coffee filter is ingenious, I will start using one.I'm surprised at how many RU-vid videos start out with removing a protective screen, which invariably does not get replaced until they are all done.Nice Job Art.

@miloo318 2 года назад

Mike, I did the same damn thing, I got distracted and missed refilling my brake reservoir causing it to run empty while pumping brakes. I have a spongy brake pedal now, which I didnt have beforehand. Can I use your method to get the air out of the brake cylinder, with the cylinder remaining on the car (Jeep Wrangler)? Im not sure this will resolve my issue bc I do have ABS and im reading something about having to bleed that too! Plus, I have since learned pushing the pedal all the way to the floor can and will damage the piston seal. I did this many times in an attempt to get all air out of the system on my brake flush.

@miatafunrun3078 4 года назад

Thanks you for making this video! I melted my stock brake pads at the track, front pistons popped out and no brake fluid. The car is still under warranty and I know the dealer would not warranty what ever needed doing... So I decided to do my first brake job. After the first bleed, I could drive it but it was spongy. Bleed, drive, hit ABS, Bleed. I did this 3 times and no real improvement. I then tried this method on the Left Front and bled the other 3 wheels. That gave a 10% improvement. Back to Home Depot to buy a 20 ft cable so I could reach all 4 wheels. I did the LF, RF, RR, LR, then repeated the LF and RF. After I saw no bubbles and a solid line of fluid in the hose. I did 50 more pumps. Now I have my brakes back! I really do think a 20 ft cable is the best because you can check the entire length of the hose to make sure there are no bubbles. Thanks!

@TechNed 7 лет назад

Thanks for the great video and tips. Couple of points I'd like to add: Even if you messed up the original task & got air into the lines, I think it was really worthwhile replacing all the used fluid with new. I wouldn't like any old fluid recirculating back into the master cylinder. The seal on the main piston is too important to risk damage so the coffee filter was a good idea but there's also rust, moisture and other grime in solution to consider - a $2 generic inline fuel filter might also have worked well there. I have a "new old stock" master cylinder for an old vehicle about to fit. The reason for the replacement is the old cylinder seal got worse after it was actuated too far on a previous brake bleed. In that case, (& the main reason we're warned against fully depressing the pedal) there was most likely a ridge formed in the old cylinder over which the seal was scraped as it rammed past, ruining it. A final point: As brake fluid is quite hygroscopic (absorbs water from the surrounding air), the whole time I kept seeing your new fluid bottle with its lid off! I wish you'd capped it between top-ups. It's the other reason the master cylinder has a sealed lid - we shouldn't leave it open to the air for too long and preferably, choose a day of low relative humidity to do a job like this. Thanks again.

I was unaware of pressing the brake pedal down too far on the brake flush/bleed job I did on my jeep and I know I pushed that pedal to the floor many times while bleeding. I follow Chris Fix and he gave me the confidence to do the job, but he makes no mention of the importance of this action. I did introduce air into the cylinder and that is why im here on this post. Im praying the spongy pedal I have is resolved by getting the air out of he system and doesnt require me to replace the brake cylinder. :(

@TechNed 2 года назад

@@miloo318 to be fair, I suspect that's only an issue on older cars like mine (a 1980 WB Holden) which probably still had the same master cylinder for 37 years before I replaced it. After so many years of the piston bearing against the same section of cylinder wall, it creates a ridge at the top of travel, not dissimilar to the combustion cylinders where the pistons reach TDC.

@TechNed 2 года назад

Btw, that new cylinder has made a huge difference because it also prevents air entering the lines like the old one used to - so the brakes haven't needed bleeding for years now. I also treated myself to a vacuum bleeder kit - a simple hand-operated vacuum pump that makes one-man brake bleeding a lot easier. I already had a one-man kit which was basically a short length of tubing with a one-way valve but the way I stow it in a jar between bleeds means it's retained a tight curl and now requires weighting to keep it vertical and in a jar (I cut a hole in a plastic lid insert to hold it in place). Mainly, the biggest issue that I have with the one-man kit is needing to be at the pedal rather than the bleed screw so I have to trust that levels are right - that I'm not overflowing and/or the bubbles are all out as well as trusting that the reservoir level hasn't dropped too low. With the vacuum pump, you just draw out the fluid and air and even though you can't see what's happening at the cylinder end, you have more confidence that everything is ok because you can clearly see how much fluid is being drawn out. It's also less hassle and much quicker to do the job.

@paulwatts9910 Год назад

I have replaced rotors and pads multiple time always successful. This time I also replaced calipers, so I had to do a lot more bleeding and, in the process, introduce air to the master cylinder. Thought I'd give your method a try, but it didn't fix the soft pedal. I had to bleed the master cylinder which I did in the car. I wasn't sure it was going to work because after removing the fittings from the master cylinder bleed kit a lot of oil was draining out before I could get the lines installed. After bleeding all 4 again I have a firm pedal and brakes are strong. I did use your tip and purchased 3/16 ID tubing which fits the bleed screw without leaking. Using the 3/16 tubing and a hole drilled in the cap of a power aid bottle sitting on top of a cinder block to get it above the bleed screw. This setup made bleeding easy without a helper. This one went 10 rounds, but I won. Thanks for your tip.

@dntlss 5 месяцев назад

When you removed the bleeder fittings from the master cylinder, that stuff you saw leaking is just remnants of whats left in the holes, technically you can get a brand new booster and fill it to the brim with fluid and it might weep a little but its not gonna empty on you (unless you leave it sitting over night), once you start using that plunger it opens the ports and then, oh yeah, you'll have fluid everywhere. The bowels of a master cylinder are a lot bigger than people think ,there's a lot of fluid in there.

@ffas23 7 лет назад

The Motive Power bleeder is a great bleeder. I purchased one just to use on my C2 and C3 Corvettes years back because they are some of the worst cars to bleed. It came with the same adapter just for the 2nd and 3rd generation Corvettes. Power bleeders mount to the top of a Master Cylinder. Comes with a large plastic bottle that fills with brake fluid. Has a pump and gauge. You pump the bottle up to a certain pressure. Can't remember the pressure but I believe it is 20 pounds as of the moment and just let it sit under the hood. You then use a bottle and clear hose and take it from wheel to wheel. Put the hose on your bleeder screw, a box wrench to your bleeder and bleed away. Sometimes you can bleed the whole car without having to pump the plastic cylinder again.

Howzit genius. End of bench bleed unless you want to remove and replace master. Brilliant idea. Two points i like to add to this procedure. Shorten the tube a bit. Prime the tube most of the way with fluid before attaching to nipple and reservoir. Im busy with trying to figure out why my pedal drops after a while on the road. Still brakes ok though. All wheels bled. Still same. No leaks. Booster and master fine. Will now try this new master bleed method and see how it goes. Its a ford ranger 2.2 diesel. Your method makes absolute sense even without the presentation. Thank you mr einstein. From south africa.

@Peppermint1 6 лет назад

If I understand well, you are simply applying the communicating vessels principle: by keeping the hose full of fluid AND above the level that's inside the master cylinder, you are forcing the air inside this system to come above. You can actually just fill the hose with fluid and insert it tight at the bottom of a jar filled with fluid located at the same level as the master cylinder, then pump the brakes a few times (perhaps even just keeping the brake pedal depressed would allow the air to come above). As others mentioned here, it may be good to repeat the same at one rear wheel (just place the jar above the wheel but at the same level from the ground as what the master cylinder is located), to bleed the rest of the master cylinder. Don't hesitate to correct me if you think I'm wrong.

@artbyrobot1 6 лет назад

It is my understanding that you are repeatedly pressing the brakes hundreds of times which churns up trapped air inside the master cylinder and you are moving that air bubble filled fluid down and out through the caliper nipple and then it ends up back in the reservoir where the trapped air bubbles surface and leave the fluid. Over time, all the air escapes according to this path. Just depressing the pedal would not work.

I never do bleed the master cylinder before mounting it on the vehicle. You can do it that way but it's a waste of time IMO. Really only have to attach line fittings loosely then fill the reservoir and wait a minute or two till fluid begins dripping from the lose fittings, then tighten them. Not so difficult.

Why can't you just run a hose from the caliper to the brake fluid on the ground isn't that the same as running it to the master cylinder as long as the master cylinder doesn't run dry

@DukeGaGa 3 года назад

This works quite well, I just did this myself with a slight modification, I attached an extra hose to my rear calipers as well. To those that don't think this works, you guys need to go look at how bench bleeding is done, it's the exact same principle as with this, pump fluid through the ports on the master cylinder until all air is gone, and there are master cylinder bleeder kits that essentially does the same thing as this, which is rerouting back the fluid pushed through the ports back so you don't need a ton of fluid. The only issue with this video is that he didn't have a hose on one of his rear calipers, which should be fine since the air got in when he was bleeding one of the front caliper, but in my experience, air will go into any space that isn't filled with other stuff, so better attach a hose to the rear as well. Also, if you really want to do this thoroughly, and bleed the master cylinder and calipers at the same time, I suggest you buy a few 3 way fittings and connect the hoses together from all calipers, then route them back to the reservoir, then just pump till all the hoses show no bubbles at all, then have a friend hold the brake pedal down when you close off the bleeder screws one by one (pump a few times, hold, close one bleeder, repeat).

@RalphSampson... 5 лет назад

This is an interesting idea. You still have the concern of the master running low and introducing air into the system, again. The hose is so long, it will take, at least, a full master cylinder to fill it. So, I don't see the advantage, unless you prefilled the hose, which you didn't. To bleed the master, simply disconnect the lines from the master and connect a hose from those holes in the side of the master to the top of it to drain back into the master. The air escapes and refills the master. Once that air is out of the master, reconnect the brake lines. Yes, there will be a small bubble at each line when reconnected but, bleed the lines again. This will save on cost of a 20' hose and an extra bottle of fluid. Your long hose also will have to be emptied when complete......waste and potentially messy. I guess I don't see this process as efficient. Wow, you just said you have a vaccum bleeder. This whole process is a waste of effort. Just vacuum bleed the system making sure to watch the level of fluid in the master this time.....done in 10 minutes. Dude, don't empty the hose until the job is done. You have to keep filling it. Better yet, just stop and vacuum bleed.

sort of but also the difference is moving 5 gallons or more of fluid through and using small pumps to aerate the fluid and get rid of the trapped air in the cylinder by churning up the air bubbles into the fluid.

I've been fighting a brake problem since April on my Audi. I've changed the master, booster and vacuum pump and am now to the point to bleeding AGAIN. I rebled my master only to have all the fluid leak out while I attached the lines which are not easy. I was thinking about bleeding a master is just a return hose, why not attach the hose to the calipers? A little searching and I found your video - you confirmed my plan! I will get tubing tomorrow along with another quart of fluid and do it the simple way. As a suggestion, instead of the coffee filter why not use a small engine fuel filter spliced into your hose? Also, if you put your tubing on the ground plugging off the open end and then gently pry the other end off the bleeder you won't spill a drop - as long as the open end is lower than the bleeder end. Thank you in advance!

@Bulletz4Breakfast13 Год назад

You can also leave the master cylinder on and bench bleed with your hands by disconnecting the two lines and having someone press & hold the brakes, and the tightly press two fingers over the master cylinders brake-line output holds while putting strong pressure while the helper let's off the brakes to prevent air coming in. Rinse and repeat and you will eventually see no air bubbles coming out past your fingers. Takes about 15-30 pump & holds! Never did this method, but I guess I could find some crystal clear silicone fuel tubing with zip ties over tube on bleeder screws.

I have replaced all my bleeder valves with speed bleeders. They have a one-way valve inside so fluid goes out, but air doesn't go back in. You put them in just like regular bleeder valves. To bleed, you loosen 1/2 to 3/4 of a turn, put a vinyl hose on the valve as usual, and pump the brakes. No 2nd person needed. I just replaced a broken brake line. After I bled the brakes, I still have pedal to the floor. I'll try bleeding the MC, and re-bleed the brakes.

You could accomplish the same thing by attaching a short length of hose to the caliper and put the other end into a bottle with enough fluid to submerge the end of the hose. As you filled the bottle you could just close the bleeder and empty the bottle back into the master. No need to fill up that long hose. That is actually a great way to bleed each caliper.

IF you can get to the fittings on the booster... no bench bleeding. You can use the fittings as bleeder valves. With them snug, have someone pump up the brakes and while they hold it, crack open the fitting on the front, the air will come out. Snug it. Have them let off the pedal.

I would never recommend letting the fluid come out from the caliper and putting it back into your brand new master cylinder, what you have now is old dirty fluid mixed in with the new fluid on your brand new master cylinder, it would have been a much smarter idea to run the hose into a clean soda bottle and topping off the master cylinder every three pumps or maybe even every two pumps, you will be able to tell when all the new fluid is coming from the bleeder valve into the bottle just by its color and when you get a stretch steady stream of Queen fluid going into the soda bottle you can close the bleeder and pull the hose off, and do that at each wheel if you want to change out all the fluid, if you're not really worried about the fluid that exists in the line already you really only needed to bleed at the farthest wheel on the front and back, pumping the old fluid from the wheel cylinder back into the brand new master cylinder is a very foolish thing to do, it is more likely for contamination to ruin the master cylinder then the wheel cylinder or caliper.

You don't need to worry about dropping brake fluid from tube or caliper when removing the tube filled with fluid. You just put a tub under caliper, close of bleeder screw and empty the hose into the tub/oil pan/5gallon bucket, then pull out top while lifting it above the hose in the bucket 🪣 Then spray around caliper and master cylinder with brake parts cleaner really well. Note: if you get any brake fluid on paint, it will ruin your cars paint and accelerate rust! Definitely clean it off. For places around electronic connections, use WD40 electrical cleaner spray. I use brake parts cleaner and shop towels to remove fluids, grease and dirt from under my Jeep, suspension and steering components as well as some parts in the engine bay while being careful not to soak electronics. You can disconnect electric connectors and put plastic over them with a zip tie so you can safley spray around them. Then I take plastic off and use WD40 Specialist Electrical Parts Cleaner

Yep. My Tahoe sat for a few years and the brake fluid was very low in the master I can't see it. So this video is for me.

well the only problem I can see that you can bleed it enough in order to get your brakes working, however, your brakes wouldn't be fully bled because they'll be some air that we'll be trapped and would not be able to be forced out... when you bench bleed you're able to move the reservoir in order to get all of the air out however you'll come to a certain point where the top of the cylinder will be with air however it will be enough fluid inside of the cylinder that will go into the line but it won't completely clear out the air left on top... the best recommendation is losing up the cylinder and at least shaking it up a little bit or just moving it in order so that you can completely get all the air out because the air is going to go to the top.. by doing that you'll be sure to get all the air out without having to completely disassemble the master cylinder.
