Brass Proportioning Valve for 2 & 4 Wheel Disc

The PV-2BH Brass Proportioning Valve is designed for use in systems with front disc brakes and either rear drum or disc brakes. This hybrid design is ideal for vehicles currently equipped with rear drum brakes that may be upgraded to disc brakes in the future. It features a 1/2 x 20 inlet for the front master cylinder and a 7/16 x 24 inlet for the rear master cylinder, with outlets measuring 3/8 x 24 for the front (two ports) and 9/16 x 18 for the rear. This GM-style proportioning valve ensures proper distribution of brake fluid pressure to both the front and rear wheels while maintaining separation between the two systems. It also includes a single wire brake light warning switch, with the wire (SP015130) available separately if needed.
