How does a proportion valve work?

A proportioning valve is a valve that relies on the statics to supply a reduced pressure to an output line. A simple example is where spring load applies a reducing force so that the output pressure is reduced. Proportioning valves are frequently used in cars to reduce the brake fluid pressure to the rear brakes.

Where is the reset button on the brake proportioning valve?

After continued use, the proportioning valve can become out of alignment and it may need to be reset. It is helpful to have some knowledge of vehicle mechanics to complete this task, but it is unnecessary. Locate the brake proportioning valve near the rear brake line. It will have one or two buttons located on it.

How do you fix a proportioning valve on a car?

Have your assistant hold the brake pedal down while you place the flare nut wrench on one of the front brake line cap nuts on the proportioning valve, if the dash light remained on. Loosen the cap nut with the wrench and have your assistant firmly press the brake pedal.

How do you reset a car brake valve?

It is an “L”-shaped metal valve. 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. If the pressure is restored to the brake line and your brakes seem to be working properly again, then the reset button worked.
