I've watched countless brake bleeding videos and this is literally one of, if not the best one so far. It says everything all the others say w/out being long and drawn out, covers (almost) all of the methods, and hits all of the important points for each method. Only thing it missed is how to bleed the master cylinder while it's already mounted onto the vehicle (which is actually what I came here looking for, lol).

@josea.melendez9631 2 года назад

It should be using the same metod as the "out off the vehicle metod"🙂

@GMoney-B 2 года назад

@@josea.melendez9631 The only thing I can figure that is the difference between bleeding the Master Cylinder when in a vice verses being attached to the brake booster, is that you could maybe tilt the Master Cylinder when out of the car to further get the bubbles out. I guess a second reason would be to see bubbles coming out and see when it finally just pumps pure fluid and no bubbles, which I guess would be great for if you are just one person doing it. Still though, scratching my head though why more people don't just bleed it attached to the car and pump it a ton of times.

@snowyowl9132 Год назад

@@GMoney-B I think the bench bleeding is all about saving you time. I tried it last night and had to settle for doing it on the car instead. I guess it'll take a lot longer but it might be the best option for me.

@HerbertAtkinson Год назад

I never had to bleed the master cylinder on any my vehicles I owned only bled all four wheels never had problems.

@jonathanrayne 5 месяцев назад

Can't you just pressure bleed the master while it's connected to the booster? Wouldn't a steady pressure of 15-20 psi force all the air out through all the lines if you just release the bleeder screws in order?

@hazehood4028 Год назад

I got brake fluid, brake cleaner, and carb cleaner in my eyes doin this, and I'm perfectly fine, just saying.

@health101DOTorg 2 года назад

You said that as the brake pedal is being pushed to the floor, to close the bleeder valve just before the pedal reaches the floor. But the person at the bleeder valve won't know when this about to happen, and the person sitting in the driver's seat won't know when this is about to happen, so how are we supposed to know when to close the bleeder valve?

@crocodile1313 Год назад

I agree with you about that and some other issues in this video. It's not a good one IMO.

@NETWizzJbirk 11 лет назад

If you don't have the clear tubing, you can push to have fluid shoot out, then just place your fingers over the ports before releasing pressure... Makes a mess on the floor, but it works.

@bFORCe2003 5 лет назад

Yep...messy but is a way to bleed the master cylinder. However you can direct the spurts of brake fluid down into a drain pan if you're skilled enough. Just dont lift your fingers right off, only lift the tips off for a split second then close back up.

@nhostetl 12 лет назад

I had to bleed my brakes with the ABS attached, You dont need the plastic screws. It would help if you guys sold them seperately, thus not having to spend $50 on a new Master Cyl. Tips for people bleeding there master: When you bench bleed your master, you can use the bleeder screw from your Caliper. Simply unscrew, and put into your Mastery Cylinder. Attach a 3/16 tube to the bleeder screw, and put other ends into Resevoir.

@bottmar1 10 лет назад

How many of you have bench bled master cylinders only to find they don't fit the car? Fit it on car first and then bench bleed it but for me, I'll fit it on the car and bleed it in place as I have for 43 years. That sequence of bleeding wheels in order really is not necessary either. Especially since the front and rear brakes are a separate system in virtually every American car since 1967. There appears to be a lot of book readers on these brake bleeding videos all over You tube.

@maveric0738 7 лет назад

Not all manufactures require to bleed from the furthest back caliper.

@Axs208 7 месяцев назад

What the hell. Just ordered one and the kit came with plugs (no hoses or plastic barbs) AND the instructions are completely different from EVERY bench bleeding video on RU-vid. They say to pull the shipping plugs, fill it 3/4 full, let it drain out the holes till steady stream, plug the holes with supplied plastic plugs, press the piston and repeat till no bubbles come out. What the hell.

@TheJeremy5599 Год назад

in the video he says dot 5 and 5.1 are incompatible with dot3 and dot4,however LITERALLY everywhere else i look, says 3,4 and 5.1 are all compatible with eachother. what gives autozone?

@crocodile1313 Год назад

If you want a video that sounds like an instruction manual being read out loud, this is your baby. But to backyard "mechanics" (like myself), I learn better by seeing things done, step-by-step. Also, the guy talking about things like a "proportioning valve," when such a valve is not even shown, is frustrating. The video quality (at max 240p) is also bad...even for 10 years ago. I think AutoZone can do better.

@acerudee 10 лет назад

good clear easy to follow instructions, a big help for someone like me who is about to do this task for the fist time.....

@multinaire 10 лет назад

Using clear tubing on the bleeder fittings, this will allow you to see the air bubbles trapped in the master cylinder. Remember, while the M.C. is in the vice and the tubes are submerged in the reservoir with brake fluid, SLOWLY apply full end to end strokes until all bubbles are no longer visible. Importantly: Use Safety Glasses! and have small zip ties, and rags available. YOU DONT WANT THIS STUFF IN YOU EYES !!

@davess357 9 лет назад

If you follow the advice in this video, you will necessarily be forcing air through the ABS hydraulic control unit and divorced proportioning valve and metering valve if your vehicle is so equipped. All you have to do is 'pop' the lines exiting the master cylinder to clear the last of the air from them. Air is not going to travel down hill by itself. It will stay close to the master cylinder.
