Why do you need a proportioning valve in your brake system?
You benefit by having a brake proportioning valve in your brake system because it helps you control brake balance. Your rear brakes may receive too much pressure during rapid deceleration if the proportioning valve is not functional. A properly-working proportioning valve ensures your rear brakes do not lock-up during heavy braking.
When to use a 2 lb brake valve?
The 2 lb. is used in a disc brake setup to prevent backflow of the fluid and creating brake drag. The 10 lb. variation is used in drum applications to help counteract return spring tension in a drum style braking system.

How can you tell if your proportioning valve is going bad?
There are a few different ways to tell this is happening. First, you might notice your car is taking a nose dive when you suddenly apply the brakes. Then your car may not stop fast enough. If your rear wheels lock up easily, especially when you drive on wet surfaces, it is a good sign your proportioning valve is going bad.
What are the functions of a brake valve?
This valve is a combination of mulitple functions, allowing proper bias between front and rear brakes. It is also adjustable to regulate rear brake pressure, as well as having a pressure activated brake light switch built in.
What to do if your brake proportioning valve is not working?
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. If the proportioning valve needs to be reset, brake fluid will not be getting through to the brakes.
How do you get a proportioning valve to work?
Bleed the rear brake line again at the proportioning valve, as you did before if you still have a brake dash light. 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.
