There is no reset on them. What will work sometimes is to completely remove the brake light switch assembly from the valve and slowly push and release your brake pedal a few times. Then reinsert your brake light switch. If this doesn't work you will have to replace the proportioning valve. New price will likely scare you so head for the scrapyard.

No reset,but you need to bleed the system starting at left front ,right rear,right front and then left rear. This sequence is best to get good fluid pressure to rear wheels.

Hi I am from Norway and have replaced my proportion valve for rear brakes on my Corolla 1996 1,3 xli wagon.I am wondering how I can bleed off air and flush back to new brake fluid.Do I need to connect a...


None of those things . Just bleed the brakes normally starting from the longest line and ending with the shortest. The proportioning valve will always let brake fluid through, just not enough to lock up the rear brakes until you press heavy on the pedal . It is there so that full pressure to the large front brakes is reduce in proportion to the smaller rear brakes.

What is a brake proportion valve function


Front brakes require different fluid pressure than the rear, as more of the braking is done by the front brakes, because of vehicle weight shifting forward during braking, etc.

Proportioning valves are used in cars to reduce the fluid pressure to the rear brakes, to reduce rear wheel lock-up.

2000 Chev Silverado 2500, Brake lines rusted and cracked loosing all fluid. replaced all lines. Got front to bleed sucessfully, but no oil to back brakes. what do I have to do to bleed back brakes?


Try opening a front bleeder and depress the pedal ALL the way,should feel a light "tic" as it reaches the bottom,close the bleeder and try to bleed the rear again,but instead of pumping ,just take the master cover off ,open the rear bleeders and wait 10 min or so for the fluid to gravity bleed out the air. Thinking the proportioning valve is tripped so no fluid is allowed to reach the rear,opening the front should reset the valve . If there is alot of air the valve will just trip again if you pump the pedal,hence the gravity bleed.

It has to be your proportioning valve, and it is probably jammed and blocking flow to the rear. You can either replace the valve or try to reset it. To reset, you need a way to put pressure into the rear brake exit port. If the valve has bleeder screws on it, try opening the front bleeder and pumping the pedal. If there is no bleeder on the valve, I have also heard of people opening the front caliper bleeders and pumping the brake to see if a little pressure in the rear will slide the piston open. No harm in trying these ideas before buying a new one, eh.

What is a load proportioning valve


A load proportioning valve is a valve that is used in the brake system that uses an arm attached to the suspension in the rear and as the vehicle is loaded, the arm allows the valve to allow more brake fluid pressure to flow through to even the braking and cause the vehicle to stop more effectively even when there is more weight in the back. Usually used on pick ups.

A master cylinder has a restricted compensator valve what problem will i most likely find with the pedal?


If your valve becomes defective then the brake pressure ratio to the front and the rear brakes will change. You will see or feel a difference. the front-end may nose dive or lock-up. The rear brakes may react the same way.

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 .

1989 K-1500 Brake Problems


Did you replace your front brake lines as these are rubber and after time collapse causing the truck to pull in the opposite direction! In your case I'd say left front is crimped and blocks fluid and makes right front pull to the right. This is a common problem and one of the first items to replace on these trucks and at $30 cheap insurance.(REPLACE BOTH).

The brake light on the dash stays on i have replaced the rear brake shoes wheel cylinders and drums master cylinder front pads caliper and rotor on my 1988 gmc 1500 pick up the light will not go out


There is a level switch in the master cylinder if the fluid level is low it will turn on the light and If you pressure or vacuum bleed the brakes you will center the proporting valve switch that warns of low brake pressure in either Front or rear.
Vacuum bleeding I have found to work the best.
Make sure the Park brake lever is all the way released. If you find this informationn helpful please leave me a favorable rating and by all means contact me if I can be of any further help.
