Proportioning Valve 87 Chevy Celebrity

My mother-in-laws car has had some serious problems with the wheels locking up. After replacing the brakes, rotors, etc. She was told by a mechanic that the only thing left to check was the proportioning valve. Where would we find the proportioning valve and does anyone know how we would go about changing it? Thanks!

Usually if the car has a valve it is mounted on the firewall. But your master cylinder has 4 connections, one for each wheel. So I doubt your car has a separate proportioning valve. You could check with the dealer to verify.

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.

It should be on the frame below the master cylinder. Just follow your brake lines off of the master to a block with a wire plug.

Brakes wont realese 87 GMC 1 ton how to check brake proportioning valve


A stuck proportioning valve will only prevent either the front or rear or corner / corner from working, it wont make them stick. More likely its one or more frozen brake caliper/s or a bad rubber brake hose/s or frozen brake cables etc.. Is it only front, rear, or both, one left, one right one side or all 4 ? You're gonna have to get the wheels off the ground even if only one at a time to check them. To determine if it is a bad rubber brake hose Crack open a bleeder screw. If the wheel then spins freely replace the hose. If it is still stuck then it is a stuck / frozen caliper, replace the caliper. In the case of rear drum brakes, you can checck the hose in the same way or if it's stuck cables you can try tugging hard on the cables to free them up some but otherwise you'll probably have to pull them apart and do a complete brake job including wheel cylinders.

92 Chevy pickup front tier heats up and shakes the vehical after driving for a few minutes


I'm going to guess that you are complaining about a brake caliper failing to release the rotor when you take your foot off the brake pedal. I had this problem with my 1989 Chev Cheyenne 1/2 Ton Pickup. The brake would lock down and the wheel would become quite warm. I replaced the caliper unit, but that didn't solve the problem. The problem turned out to be a bad flexible brake hose at that wheel. Incredibly, these hoses wear out and are susceptible to collapsing internally causing a restriction in the fluid flow. The hose looked fine from the outside. Once a put a new one on, problem solved! This might be your problem, too.

Other causes could be a malfunctioning proportioning valve, a malfunctioning power brake booster unit, a binding brake pedal, binding brake pads or a sticking piston in the caliper.

That would likely be caused by the ABS brake hydraulic control unit leaking pressure to the rear brake caliper, not the proporting valve..

My 1996 Chevy cavalier recently failed inspection because the rear brake locks up. are the any reasons that this is happening? and what can i do to fix this problem?


1st , make sure that all of the brake springs is not losing their tension, or not working properly, if this checks out ok, then check out the proportioning valve, this distributes brake fluid pressure to all 4 wheels.

Villager GE 95 liquid escape in a brake system


It is a brake load sensoing valve that applies more pressure to the rear brakes as you load the vehicle. It is $375 from tascafordparts.com. Get one from the junk yard or just bypass it.

usually just the lines are leaking and can be replaced.
Valve, Brake Load Sensor Proportioning The Villager has a brake load sensor proportioning valve (2B547) that is mounted on the vehicle frame and connected to the rear axle housing (4010) . When the vehicle is unloaded, the brake load sensor proportioning valve closes and partially reduces hydraulic pressure to the rear wheel cylinders (2261) . As the vehicle is loaded, the weight presses down the back end of the vehicle on the rear springs (5560) . This activates the brake load sensor proportioning valve which opens and supplies more hydraulic pressure to the rear wheel cylinders . When the vehicle is fully loaded, the brake load sensor proportioning valve is fully open and provides full hydraulic pressure to the rear wheel cylinders .

My abs light stays on 1995 chevy G20 van and have to replace front brakes every 6 months but rear brakes show no wear and are atleast 3 yrs old. On slick pavement right front brake sometimes locks when...


I'd be checking the sensor (ABS) at that wheel, (right front) and adjusting rear brakes to proper clearance, as well as inspect them for proper operation with wheels off.

99 Jeep GC Brake Lock


todays sports utility vehicles are equiped with a proportioning valve. they are usualy located at the rear of the vehicle. this valve regulates the flow of brake fluid to the calipers. most suv`s have a ride control arm on them that is linked to the rear suspension to apply more braking force to the rear wheels in a harsh or sudden stop. if this valve is bad or malfunctioning even body roll can redirect brake fluid to the rear wheels causing them to lock up., hope this info helps
