Proportioning Valve

DESCRIPTION









There are two proportioning valves used in the antilock brake system. One proportioning valve is located in the chassis brake tube leading to each rear wheel brake hydraulic circuit. They can be found to the inside of the right frame rail. The proportioning valve can be identified by its bar code label and stamp. Be sure a replacement proportioning valve has the same stamp as the proportioning valve being replaced.

OPERATION
The ABS proportioning valves function the same as the proportioning valves in the base brake system.
