How to Reset a Brake Proportioning Valve

1. Locate the brake proportioning valve near the rear brake line. It will have one or two buttons located on it.
2. Push the reset button located on the valve with your fingers, which will reset it so the valve is working properly again. Inspect the brake pressure.

Can you bypass a proportioning valve?

The valve will only work as designed if the rest of the suspension retains the original specifications – if your car is significantly lowered or the suspension stiffened up, you might as well bypass the proportioning valve.

Do you need a proportioning valve with 4 wheel disc brakes?

If I add disc brakes will I need a proportioning valve? Yes. The addition of a proportioning valve is a must. Without it your braking system will not operate properly.

Do you have to have a brake proportioning valve?

A Proportioning valve is required on vehicles that have disc brakes on the front wheels and drum brakes on the rear wheels. Having the rear brakes engage first provides the control and stability needed to stop your vehicle safety. The proportioning valve reduces the pressure to the rear brakes.

What is inside a brake proportioning valve?

The proportioning valve typically connects the master cylinder to the rest of the braking system, but sometimes it is independent of the cylinder. This valve is necessary for optimizing front-to-rear bias, also referred to as brake balance. Then, the valve’s plunger unseats and fluid rushes into the calibrated range.

What happens when a brake proportioning valve fails?

A faulty brake proportioning valve could increase your vehicle’s braking distance, as it might reduce the pressure from the rear brakes too much. Note that the symptoms of a bad brake proportioning valve may also point to damage to other components, such as the rear brake circuit, brake caliper, or wheel cylinder.

How do you use adjustable proportioning valve?

Start with the valve in full open position by turning the knob counter clockwise as far as it will go. 2. Make several stops from 30 M.P.H. If the rear brakes lock up before the front decrease the rear pressure by turning it counter-clockwise one full rotation at a time.

How does a height sensing proportioning valve work?

Height sensing proportioning valves are connected to the hydraulic lines leading to the rear drums located between the vehicle’s chassis and the rear axle. It has a lever that moves a valve to restrict fluid pressure to the rear brakes as the vehicle’s chassis raises up and away from the axle.
