Where is the brake proportioning valve located?

The proportioning valve is mounted between the brake line master cylinder and the rear wheels. It’s designed to adjust the pressure between the front and rear brakes, depending on how hard you’re stopping. The shorter the stopping distance, the more of the vehicle’s weight is transferred to the front wheels.

This type of valve is Usually mounted to the frame or inner fender below the master cylinder.

Yes. The addition of a proportioning valve is a must. Without it your braking system will not operate properly. Can I re-use the old drum brake valve when I change over to disc brakes?

This will cause the rear wheels to frequently lock up why is why the proportioning valve is there to reduce rear wheel lock on application. In practice, These valves are not considered to be repairable And if bad they are replaced.

Proportioning valves are frequently used in cars to Reduce the brake fluid pressure to the rear brakes. In cars with disc brakes on the front and drum brakes on the back, more pressure is needed for the disc brakes in the front.

A Brake Proportioning Valve is commonly found on vehicles with front disc and rear drum brakes. It is A safety valve that restricts flow to the rear brakes during a “panic stop.” This prevents the rear wheels from locking up before the front wheels.

The Proportioning Valve keeps the rear brakes from locking up during a panic stop. The Metering Valve delays the front brakes long enough for the fluid pressure to overcome the rear brake return springs.

The proportioning valve Prevents the rear brakes from engaging before the front brakes during panic stops.

A proportional valve opens by an amount which is proportional to the control signal. For instance, 50% signal = 50% open. A directional valve sends the fluid into a desired outlet according to the control input.
