brakes wont bleed proportional valve reset this guy's garage

some times when you can not bleed the brakes it is because the proportional valve has been activated and wont allow a part of the brake system to be properly bled. so follow along to get help with this issue

I’ve been working on my daughters brakes for days. I was just about to take it to the shop, before I saw this video. You are my new best friend

THANK YOU! 1999 Dodge Durango went to five (5) ASE mechanics for horrible brakes, new master cylinder (twice), new rotors, new shoes, babied...bad brakes. Then SUDDENLY, bad went to worse as the front brakes were almost lost the ABS system went nuts. Your "last resort" was done. Fed up with mechanics I researched and came to your sight by accident. It made sense. Opened the front and rear bleeders and brake fluid gushed out the front, hit it with air at the back, bleed the system and viola! For the FIRST TIME in 22 years I have great brakes. THANK YOU. I kid you not, 5 mechanics didn't find that problem. ???? ...and I spent some money over that time.

Awesome, this is the first result I've been. A garage mechanic for a long time and never had this happen

I really appreciate the tips in this video as I just finished rear brake lines on a 1999 lexus es 300 and the proportioning valve was stuck badky only giving fluid to the fronts. I didnt have a bleeder in my master cylinder and the 2nd tip for unsticking it didnt work so I had to do the hail mary approach and it fixed the issue immediately! No sooner than I shot two puffs of an airgun into the rear bleeder that fluid started rushing out. Bled all 4 using the air compressor tool you refer to and lastly two person bleeding and Im back on the road. Thank you for making these types of videos!

I found this video a couple days ago. I want to thank you very much for posting it. It helped me a great deal.

My buddy bleed system is using one of my 4” decorative yard blocks that you can buy at Lowes. These blocks are heavy enough that once you have pumped your pedal and are in the hold position, you wedge that block against your pedal and it will hold it. Then go crack your bleeder and then close it like normal. Once again go to the drivers seat and move the block. Pump, pump, pump and hold. Wedge your block and make sure it holds. Go crack your bleeder at your wheel and close it back. Follow your manufacture’s pattern of which wheel is bled first. 2nd, 3rd and finally 4th. This method doesn’t require you to depend on whether or not someone can hear you and you know that the person didn’t release the pedal before you close the bleeder at the wheel. It works like a champ.

Dang this might have helped me out the other day. Had to put a master cylinder in a chevy silverado with abs, and I've never had so much trouble bleeding brakes before. I bled the brakes and the ABS pump about 5 times with my scan tool. I finally broke down and bought about a 300 dollar pressure bleeder, which I must say did get the job done.

Thank you!! I had a leaky master cyl on my 1980 firebird. After bench bleeding the new one and installing it, couldn't get the rear brakes to bleed. Very little fluid coming out. The brake light was on dash, indicating the prop valve triggered. I tried various brake pedal and cracking tips to recenter. No luck. Then i found your vid. I dont have vac bleeder so i went to the air gun method. That blew the prop valve the other extreme. Light was still on, but i could bleed rears no prob. When i moved to front, they bled no prob and the valve recentered and light went off. All good. Thank you from Hamilton.

[matthewmiller]

You are the man. After looking at dozens of lame video that really had nothing to do with the issue I got on to yours and you succinctly intelligently laid it out exactly how it is and for that I appreciate it great stuff.

[chazzwins]

wow I never thought about the air method. My 88 Lincoln Town Car has a stuck proportional and I cant find the part anywhere. Im going to try and force some air through. I will let you know. Thanks for the great information.

[derekjohnson]

Thank you for this Video... After watching this I went straight for the Hell Mary option, and Wahla it worked!!!! I didn't try anything else you demonstrated, im just glad the Hell Mary version worked... I have solid

[meagaindave]

TGG! I've said it before and I'll say it again. I don't always comment, these days, but i LIKE everything you do, man! Cheers and God bless! 😁🍻👍

[OnlineAutoRepairVideos]

HEY, I have the same bleeder!! You are 100% right about not solely depending on that bleeder, because I don't either! Sometimes its just not as good as the always perfect buddy system. I'm digging the HAIL MARY method, LOL! Great instructions Shaun!

@ 4:07 Thank you so much for this film. I even didn't know that the Master Cylinder has a Breed Valve. I was appealed by the name of the film, since yesterday completed the Bleeding of all 4 wheels, and not all the wheels responded in the same way. It was easier to bleed the front brakes than the rear. The car was 2009 Nissan Sentra and the order of bleeding there is:
RR, FL, RL, FR ( a different order than on most cars). All the brakes were bleeding, but the rear pushed the brake fluid so much harder, than the front. I thought it is some peculiarity of the car or work of the brake system, and thought to do research in the future on that phenomena I observed yesterday. But today fortunately I came across this film, and now think maybe there is some problem w/Master Cylinder of that car. It was rather hard to pump RR, much easier FL, very hard RL (though I pumped the fluid into the hose like for 12"), and very-very easy to pump FR. Till the extend that I thought if to flush the whole system well (like 2-3 bottles) you are supposed to use just Front Brakes, bcs if you pump the Rear, it will take forever to pump those 2 bottles. Thank you again.

Great information, Thank you, Mr Guy, boy never had problems with changing out caliper and I ran into a problems, your information helps to understand now never knew this thank you again

[Faith_Family_Firearms_Freedom]

Thank you for the vid. In my 94 silverado, the proportional valve was tripped, but to the rear of the valve and the manual reset only resets if it trips to the front of the valve. Had to take off line to front brakes and do a quick pump, and that tripped it the other way and then I was able to use the manual reset to center it a again. Now back to figuring out why I have air continuously coming out of left rear.

[carlodonnell]

Hi I have a vacuum bleeder...and I learned the hard way that vacuum bleeding the rear brakes of my 2001 dodge ram cargo van causes the brake switch to go offcenter and the brake switch lite comes on ....is there a way to vacuum bleed the rear brakes without the brake switch lite coming on or do I just avoid vacuum bleeding the rear brakes?

[ajwalou-nack]

Excellent information.What i did was the same but i put a container on the rear brake bleed valve and filled it with fluid. When i sucked the fluid out the master cylinder it automatically filled the brake lines with fresh fluid.
