Mustang Disc Brake Proportioning Valve Rebuild Kit 1970-1973

Disc Brake Proportioning Valve Rebuild Kit for 1970-1973 Mustangs.

Quality kit for rebuilding your disc brake distribution block combination proportioning valve on 1970-1973 Mercury Cougar and Ford Mustangs. Special molded and round O-rings are made from EPDM (Ethylene Propylene 70 Durometer) which is designed specifically to withstand chemical degradation caused by prolonged exposure to brake fluid.

The spring is custom made from the exotic alloy INCONEL, which will never rust and will retain its factory specification compression strength many times longer than the originals.
