SOURCE: did brake job on 1992 chevy pickup, how do I release proportional valve?

some times you get an air bubble and you just cant get it to pass. you can work very hard and still not get it to bleed. snapon sells a bleeder system that sell for around $500 but i can tell you how to build one for under $20. if interested. but your answere is to back bleed the system from the farthest away wheel first. and then your peddel will come back.

SOURCE: 1989 chevy caprice proportioning valve

The proportioning valve can be mounted on the frame or just off of the master cylinder. Yes, you can buy aftermarket and no you don't have to stay OEM on it.

What does the proportioning valve do?


Assuming you're talking about the brake system...
The proportioning valve is on the rear brakes only when the vehicle has rear Drum Brakes.
What it does is limits the brake line pressure to the rear brakes during normal stopping. This way the rear brakes don't lock up and cause the vehicle to fish tail or spin.
When you press the brakes harder than normal, the proportioning valve opens more to allow more line pressure so you're able to stop faster.

Rear brakes lock when press brake pedal.


get is serviced.

its stuck in , low bed (loaded) mode. the lever is or parts in side

stuck in full load mode.

and guess what, if you bypass the valve, what will happen

the rear brake will lock, going fast and if on wet or worse roads. 10x worse. its there for a reason. to lower the brake pressure with no pickup bed load. or not heavy trailer tongue weight.



ever consider the rear brakes are bad. first. and not the valve.



service the rear shoes and slaves.

then check the bypass.



Does the truck still have the height sensing brake line bracket and line connected into the prop valve?

Brake proportioning valve


It could be your break line is clogged with air bubbles or your brake pads/shoes are contaminated. If not that I'd say you need to replace your master cylinder. You can buy a used master cylinder online for pretty cheap.

I just replaced the brake master cylinder and rear wheel cylinder on my 1987 toyota pickup, and now I have no fluid going to the back brakes. Bleeding them does nothing


check for fluid before and after the proportioning valve by disconnection the line after the valve and applying the brakes, if no fluid after valve try before valve if fluid is there then it is a bad proportioning valve. you did bleed the master cylinder before connecting the brake line and trying to bleed the brakes all at once right? If the master cylinder was not bled first then a lot of air may have been forced into the rest of the brake lines.

I need to know if a brake line Junction Block is the same as a proportioning valve?


no a brake line junction block will give all of the brakes equal pressure and wear the back brakes out faster then the front if your car is not made for it a proportioning valve monitors the pressure on each brake and distributes it accordingly

My brakes r leaking inbetween the two rear tires n its doesnt look like any proportional valve i ever seen


Grand Ams don't use a proportioning valve. The rear brake lines should split above the rear trailing axle and go to each wheel. They have rubber flex lines that attach to the metal brake lines, but I'm not sure what valve you are talking about, or exactly where.

How to bleed brakes on 98 regal, I changed rear brake lines but I don't think fluid is going thru the proportioning valve or ABS. I am used to the older brakes ( 70's and down.)


sometimes you can tap on the proportioning valve while someone pumps the brake if nothing breaks loose you may have to replace the valve.

The rear brakes seem unable to bleed. i think the proportioning valve bad.


You are correct in assuming the proportioning valve,but it may not be bad,if it detects,loss of fluid pressure,it will shut down those brake lines.Try bleeding the master cylinder,then the wheels,and you may have to do it a couple of times,this will allow the proportioning valve allow the wheels with fluid pressure,if this was at all helpful,please rate,thank you,

No brake fluid flow to right rear brake


the stratus is know for clasped rear brake hoses .This stops the flow off brake fluid. try opening the brake lines at the master cylinder that go to the rear.pump up brakes first! if you got fluid than check the brake line if this is rear disc brakes on the line at the rear will be a built in proportioning valve.if drum loosen rubber hose line before the rubber part to see if you have fluid. If you do replace the brake hose! On you 74 challenger by the way i love dodge! any way on the valve there is a small button on the front of the proportioning valve that pops out it needs to be tap in lightly. also hit the brake peddel kind of hard a couple off times if that doesn't work. thanks for your question


p.s that hex bar on the is a junction not a proportioning valve .
