What does a brake distribution block do?

What does a brake distribution block do?

A Distribution Block has the job of distributing brake fluid to the different brake lines in the brake system and typically has a failure warning switch in the event of a half system failure (IE: rear brakes go out).

How do you reset a brake distribution block?

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.

How do you unblock a brake proportioning valve?

Bleed the front brake lines on the proportioning valve in the same fashion. This reversal of pressure will eventually break the spool loose inside the proportioning valve, equalizing the pressure between the front and rear brakes. The dash light will go off.

How does a brake proportioning valve work?

It is a spring-loaded component that activates when fluid pressure builds when you step on the brake pedal. Then, the valve’s plunger unseats and fluid rushes into the calibrated range. Once this happens, the spring gets compressed and the plunger blocks the fluid from passing through.

What is the difference between disc disc and disc drum proportioning valve?

A proportioning valve is in-place to mediate the applied pressure differences between the front discs and the rear drums. As we all know, the discs do more of the stopping duties than the drums, therefore, more pressure is applied to the front discs.

Why can’t I get brake fluid to my back brakes?

If there are no brake fluid pressure rear brakes, check for the pipes that deliver brake fluid to the rear brakes. Sometimes these pipes are exposed to corrosion that makes them have holes and leak the brake fluid. This makes the rear wheels not to bleed air, and make no pressure in the rear wheels.

What happens when a proportioning valve goes bad?

Since the proportioning valve decreases the pressure sent to the rear brakes, the main symptom the valve is going bad is the rear wheels locking up when the brakes are applied. Furthermore, the wheels will lock up more easily on wet surfaces. The rear brakes may feel touchy when applied even gently.

Why am I not getting any brake fluid to rear brakes?

Do I really 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 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.
