Bias Valves

Proportioning Valves

AP Racing's range of Proportioning Valves have been specially designed for use in competition vehicles where it is desired to reduce the hydraulic line pressure and therefore braking effort of the rear brakes to compensate for varying road/track conditions or vehicle handling characteristics.

WARNING:
- Due to internal adjustments set by AP Racing, do not strip these assemblies.
- DO NOT attempt any modification of these valves. 

NOTE:
These valves are suitable for use with any brake fluid that conforms to DOT 3, DOT 4 or DOT 5.1 standards, but best all round performance will be achieved with either AP Racing PRF660 or 600 brake fluids.
