Master Cylinder and Proportioning Valve Kit, Firewall Mount

When upgrading your Vehicle from drum to disc, these small items are a must. These components ensure proper fluid transfer and contain a residual pressure valve for proper braking feel. Proportioning valve mounts underneath the master cylinder. This valve is designed to isolate the front brakes from the rear brakes in the event of a failure, the emergency shut off valve detects a change in pressure and closes that portion of the brakes.
