The 12 Best Rear Disc Brake Proportioning valves (2023 reviews)

Next on the list, we've got yet another valve that manages to win our hearts. It's the wilwood rear disc brake proportioning valve and it's widely considered as valve that has the most suitable features. This unit is more for dividing pressure to either front or rear of the vehicle where it is needed the most it should work whether it's four wheel disc or disc and drum. It is great for setting up a disc-drum brake system on a project car or truck. It comes with oem distribution valves if you have a leak in one brake line and it will shift a spool in the block setting the brake light on the dash. If you are running them on the front brakes, the brake light solenoid will be triggered so long as the line locks are holding pressure.

This unit has a pressure switch built in but it is to activate the rear brake lights any time there is any brake pressure at all, not to indicate a problem. The front and rear circuits are kept separate and the switch you see is to activate brake lights or similar. It needs to be mounted in an easily accessed location. The purpose of this is to regulate pressure between the front and back brakes, treat the inlet as power in and outlets go to front and rear sections as separate paths.
