Prius Brake Bleed no Scantool 

Replaced the brake actuator on my 2009 Prius and used this video to bleed the brakes with no scan tool. Worked perfectly! Thank you!

This video was so much better than the other videos, and only took a few minutes and worked great. Thank you!

I replaced a front brake hose and used this method and it worked absolutely great! Thank you so much Mr. Electric

Not only a great video, but you kindly take your own time out to respond to all questions asked and for that, it is very much appreciated.🙏

Thank you for the demonstration, now I know and less nervous about working on my prius now .

Your method worked perfectly in the ES300h 2018. It is much easier and faster than the normal method with non hybrid vehicles.

Thank you for this video for such simple and effective way to bleed the brake lines. It helped a lot. As I noticed, I just used the carpenter's clamp to depress the pedal. The handle on the clamp should be turned around 180 degrees and it works very well. Good luck to all DIY enthusiasts!

This is awesome 👌 !!! I was bleeding the car with the car running, it went nowhere !!! Thank you for this!!!

Awesome. Using this method I was able to rebuild and then bleed a rear caliper that I pulled the piston from after the dust boot came out doing a brake replace. This method was crazy easy and the brakes work perfect. No lights on the dash of my Prius either. 🤘

Worked perfectly. Just change rear cylinders 2009 gen 2. THANK YOU!

Definitely works. I noticed that the pump/accumulator wasn't running the whole time like in the video. Still worked out fine.

Wow. Thank you so much on this process.

great video - I did this today and it worked great on all 4 corners. I was just bleeding my old fluid out, no module issues, etc. I went thru 3 pints of toyota dot3 on my 08 prius, i wanted to make sure all of the old fluid was bled out.....I do not know if it matters or not, but I had the key fob in my pocket but kept the car completely turned off.

Brilliant method! If you just need to replace the fluid, I'd guess this is just as good as doing it the 'official' way...

Thank you !!. I used to bleed brake oil using this method. My car is TOYOTA Corolla AXIO (JDM) 2017

definitivamente funciona al 100% y dice q el secreto es abrir la purga primero y después pisar el pedal del freno lo acabo de hacer y me funciono perfectamente saludos

Thank you. Instead of paying 25-75$ for that brake tool, I used a caulking gun and 18" clamp. You can use a long rod or stick that fits in the gun. Adjust the chair and press the brake.

Went to the conventional method using a scan tool and got the brake pedal back. Everything good now. Thanks

I just loved it.. Thank you tech nice

Wow. This is sooooo much of a time saver and simplifies this process on the Prius. If I followed your demo correctly, this is my written summary of the process you demonstrated as I understand it: 1. Cycle Engine on then turn off.
2. Key near/in vehicle.
3. Bleed bottle attached.
4. Open bleed valve. 5. Depress and hold down brake pedal. 6. ABS Pump should activate, bleeding brakes.
7. Close bleed valve (ABS Pump stops).
8. Top off reservoir.

You should do every car repair video on RU-vid!

Great video. Got all the info in 3mins...

Thank you for posting this video. It is elegantly simple and easy and I plan on trying this out after we get rid of all these hurricanes. Looking forward to seeing you bleed the ABS actuator, hopefully. I haven't done mine yet but I'm sure my day is coming. I'm just using the Frontier most of the time to delay that day. I've come to the conclusion that it is something rubber that's deteriorated. The extended run time is the only issue and it works great otherwise. It's a shame there aren't any shops that rebuild these actuators that I could send mine to and have them repair and reseal it and return it back to me. Maybe some day....

I am a fan of the accumulator braking system.

Thanks.. wow. What great information.

This seems unbelievable easy, can't grasp the ScanTool method being any better...

I love your watch ''vintage electronic Casio'' from Japan of course as your mostly repaired cars 🤣

I finally got the two dreaded codes after months of holding my breath and waiting for the ABS actuator to light up the dash. The pedal doesn't feel any different and the brakes still work well, but it's time to swap it out. I found one out of a 2007 Prius with 136,000 miles from a salvage parts company on EBay. The seller offered a 3 month warranty on the part, while most of the others only warranted the part for 30 days, and some sellers not at all, since it is an electrical part. It was a little under $300 with Fed Ex ground. The three month warranty will allow me to install it and make sure it works. The part is clean and the actual harness was cut, leaving the connector intact. They used plenty of bubble wrap and it arrived intact without visible damage. When I made contact with the owner, the actuator was still in the donor car and was not removed until I had paid. Hopefully the internals will not be able to dry out from exposure to the atmosphere for too long. I will start disassembly this weekend using your other video.

Awesome video! you make it look easy. I like how you prepped everything ready to go ahead of time. 99% of car videos aren't this good. I wish you had some Amazon links to that pedal depressor.

This technique worked for me, however I had some screw ups along the way. For 2 days in a row, when I pressed the brake pedal to start the car, I noticed the brake pedal dropped a bit twice. On the 2nd day, the ABS light was lit on the dash, and the car would not start. I decided to replace the brake fluid to bleed all the bubbles out to see if this would fix my problem. So far this seems to have worked. 1) I used a vacuum pump kit to suck most of the fluid out of the reservoir, below the lower line. I then filled the reservoir up to the max line, and placed the cover loosely onto the reservoir. 2) I did this one tire at a time, using the factory jack. I started by removing the left rear tire (furthest from the ABS actuator). 3) With the car off, I broke free the bleeder nut, and retightened it. I attached a hose to the bleeder nut, letting the hose fall down into a bottle. I loosened the bleeder nut about 1/5th of a turn. Without starting the car and without opening the driver door, I inserted a 1 1/2 foot board between the driver seat and the brake pedal. This lit the rear tail lights and also activated the ABS actuator. It turned on for about 5 seconds, off for 3 seconds, and back on for 5 seconds, and repeated. I let it run for about 40 seconds, and then closed the bleeder nut. This flushed that brake line. I tightened the bleeder nut, and put the tire back on. I didn't notice this at the time, but I think this drained the 12v battery. 4) I started the car and turned it around in my garage. I removed the right rear tire, and attempted to perform this same procedure, but I did not hear the ABS actuator turn on. I suspect my old 12v battery did not have enough juice to turn on the ABS actuator. As a workaround, I used a vacuum pump to manually suck the brake fluid out of the caliper. I found I had to insert a board between the driver seat and the brake pedal, to allow the fluid to be sucked out of the caliper bleeder nut. Even though the ABS actuator was not being turned on, this allowed the fluid to be sucked out. I charged my dead battery overnight. 5) The next day, I connected the charged up battery. I noticed the ABS light was lit on the dash. It would not turn off. 6) These steps work for one wheel. Disconnect the battery and charge it up. Connect the battery to the car without turning the car on. Jack up the car, and remove the tire. Ensure the brake fluid is filled to the max line in the reservoir. Attach a hose from the bleeder nut into a jar. Loosen the bleeder nut 1/5th turn. With the car off, with the FOB nearby, insert a board between the driver seat and the brake pedal. This will turn the ABS actuator on, and will drain fluid into the jar. After about 20 seconds, tighten the bleeder nut. Remove the board that is pressing on the brake pedal. After doing this, check the voltage of the battery. On my car, it drained the battery to about 12 volts, so I started the car to charge the battery back up. 7) I then did the next tire. So if you have enough battery voltage, this technique works. 8) Clearing the OBD2 codes will not turn off the ABS light. Removing the battery leads will not reset the ABS light either. That being said, there is a way to reset the ABS light on a 2nd gen Prius. Find the OBD2 port under the dash below your right knee. When looking up at it you will find a connector with 2 rows of 8 pins each. Connect a jumper between pin 4 (CG pin) and pin 13 (TC pin) on the OBD2 connector. Starting at the top row reading from left to right, pin 4 would be the pin 4 pins away from the left on top row. On bottom row pin 13 would be 4 pins from the right on bottom row. Connect the two pins using a small paper clip, then start the car putting the car into ready mode. It will start blinking the ABS light on the dash and the touch screen display will not look normal. Press the brake pedal 8 times or more in 5 seconds after turning the car into ready mode. Turn off the car and remove jumper. The ABS light will not be on. This procedure only resets the light, not the underlying problem. If the original fault is not repaired the light will come on again. In my case I did a brake job on the car and the abs light came on because I moved the piston back in the caliper. The abs system detected a pressure difference between wheel cylinders setting the ABS light. 9) I think it may be time for me to buy a new AGM 12v battery.

Amazing! Strait to the point!

Great job man! I'm about to buy a prius with a bad abs accumulator for cheap. I think I can fix it after watching your video.

legit video and demo, thank u

Aloha Mr. Electric! I have a 2019 Camry LE Hybrid. Do you know if this same method will work on my car?

Is this what you do after you swap out the brake pump thing?

Thank you sir!!!

Thank you!!

Thank you....

Great video, thanks for posting! But I have a specific question...I need to put a new front caliper on my Gen 2 2007 Prius. So of course the caliper will be completely empty of fluid when I go to bleed it. Will the method you show in this video still work if the caliper is completely empty? Or will it produce the ABS/VSC lights and codes? Thank you.

just to follow up with my first question, the abs actuator will be replaced

Sorry for the silly question, but could I completely flush my entire brake fluid system using this method on a Gen 2 Prius, or is it just for a short bleed? If so, do I just leave the bottle on for a longer period of time and keep the reservoir topped off?

Hey, why depress the pedal while the bleeder nut is open? Wouldnt that suck air in from the brake line?

Quick question on the rear brakes, once you have one side done on the rear do you remove the depressor and complete the other rear side in the same manner? opening the value and then applying the depressor? and then move to the front brakes?

Did you teach auto shop at CCSF?

Hi. Are you sure that doing in this way the old fluid was bled out from ABS pomp ?? master cylinder, stroke simulator? I have to change the brake fluid in the brake system and I do not want the remains of the old one anywhere? thanks for your Answer

So much easier 👍

Do you need to have the cap to the brake reservoir off when doing this? seems that would allow air to get in the system

Hi there. Thanks for all your videos. I watched your other video "Prius ABS actuor replacement". So I was wondering if you can use this brake bleed method after your change your ABS actuor or you need a computer to bleed them? Sorry for my english. Thanks a lot

where you at located sir?

Does it work on Prius 2008? I tried it on rear wheels which are drum brake. When I opened blead valve and depress brake padle, a little brake fluid came out and no more out, so I closed bleed valve. The result is my rear break lost brake. I have no idea what is wrong with the steps I followed here.

Thanks

Can you help me repairing the hybrid battery😔

I just replaced my prius gen 2's abs. to bleed the abs, you're saying doing this would be enough: with the car off, open the bleeder nut, and then push on the brakes. and open and close the driver door to have the pump running again for the front two wheels to bleed. that's it? this sounds so fast! i'm excited and thank you so much for this information.

Great video. Does this work on Gen 3 (2010 - 2015) Prius, and Prius C?

My ABS pump is not on for 2005 Prius ...there is no activity. Had it replaced at dealership year and a half two years ago. I believe I am disillusioned. Reason I'm watching your video is because the scan tool shipped to me is programed for the wrong region and is being shipped back to seller. Got the Prius securely on 4 jack stands and might have to end up turning everything on to force the motor to run to see if I get any activity back at the drums brakes

great method but I would still remove the two ABS MR relays to bleed the front ,back is ok with relays on. Techstream bleeding procedure asking for it ,must be a reason.

Can this be done with the vehicle with key in the ''on'' position?

How is the abs pump going with the care off?

Is the brake depressor tool necessary or can I have someone else press on the brakes?

Is this sufficient to do after replacing the ABS module? Or do you need the tech stream?

Can you elaborate on getting the key FOB near the car during this procedure. Bad idea?

Thank you for sharing. Could you please let us know the wheel sequence for bleeding the breaks? Start on the rear passenger? Thanks in advance.

Hi i have a question i seen ur video good but u not told abt the ignition on car off or without ignition on this method?

Hey @Mr.Electric , I did the abs module/pump following your other video but my codes still on dashboard you think abs module I bought was bad also? And when bleeding breaks do you press pedal all the way down?

Ive got a dumb "linear solenoid valve offset unlearned" code in my abs system. The car won't make it through calibration and jumps out in under a minute. Would flushing the brake system possibly help?

Can I bleed the brakes with the prius in ready mode? Like, can i press the brake and it pumps the fluid with it turned on in ready mode? My 12v battery is going bad and I cant press the brakes many times with the car off or it will quickly drain the 12v battery

Does this method work for Prius gen 4; 2018 model? Thank ou.

Prius 2006 .I replaced the hub in the left wheel and after installing it and driving 200m, 3 lights appeared on the dashboard. can you help me on this?

Thank you for your video!! I followed your instructions for "Prius Brake Bleed No Scan Tool" on my 2009 Prius after replacing the ABS pump. On the rear wheels it worked as it is shown. On the front the ABS pump does not come on. I do not have any pedal resistance and it goes to the floor. What should I do to get the front to bleed?

Do you have to remove the relays? I bled them without removing any relays and now the check hybrid system message came up

Buddy please an answer after bleeding the abs and stability control light went on and and Looks like abs is not working. 2012 prius 166k Miles before everything was good. Any video or tip of what it can be?

So what if you already have some warning lights on ? I’m sure bleeding it won’t make the lights go off right ?

The key inside or outside the car? I kept in the cup holder while the car is off and abs went off 1 time only.

How long do you let the pump run for? Like, how long does it take for it to bleed completely?

Do you know if this will work on my Camry hybrid?

When bleeding the brakes do you need to disconnect the 12v and hybrid battery?

If you replace the abs module pump, do you do the same procedure?

Worked for me…..so far

Do you think this would work for a 2006 Toyota highlander hybrid ?

Mr. Electric mine I forgot to bleed and it throws code abs vcs error. Can this bleeding process remove the error on dashboard? Please help

will this method work for 3rd generation prius?. also can someone just press on pedal in car without the pedal depressor device? just push hard or lightly if plan to have a person help me?

would do you mean by codes. there are no codes on dash board right now. do not want any codes to pop up after bleeding because i would not know what to do to clear it.

Does the prius has to be on? That wasnt mention in the video

Does this work after replacing the brake actuator?

Will this work after changing master cylinder on 2010 Prius?

You didn’t say whether or not the car was on electrically or not. So I assume that you pressed the starter button twice without your foot on the break so that it wouldn’t turn the engine on. Am I correct?

What year of hybrid toyota is this?

I have a precollsion code sayinv abs is failuy and asking to do a linears solenoid learn is bot working because of the pcs code. Any suppestion?

I tried bleeding the rear caliper on a 2008 toyota camry hybrid i did a similar method where i had someone press the brake pedal down while i opened the bleeder valve although i did this multiple times and after a few times no more fluid was coming out of the bleeder and abs lights are on, any suggestions on how to remove the abs lights now?

does the bleeding bottle need to be airtight?

Did you have to leave ignition on thru the process ?

Does this only work with the Toyota hybrids? Why does it work tho, how come the ABS pump kicks in when the car is off?

about after an actuator abs replacement ? do you bleed the same way ?

my brake pedal 2010 prius feels softer that normal. should i bleed it 🤔

Do I have to do on other side too or just driver side only. Thanks

This needs to be done before removing the lines of the brake actuator and removing the unit?

So just to make sure...when bleeding the Prius using this method the car is completely off and not in any mode? thanks for the great video

After getting the codes and warning lights for abs failure, I replaced the entire abs actuator and pump assembly. no more lights on dash and checked with a scanner, no codes. I followed the procedure you outlined in the video and bled all four brakes. However, I still do not have a brake pedal, goes to the floor. Can you advise please? I have a 2008 Toyota highlander hybrid.

How do you when when it is done bleeding?

Would this work on a 3rd gen?
