1967-1969 MUSTANG 9" ZINC SINGLE DIAPHRAGM BRAKE BOOSTER, INCLUDES PUSH ROD & CHECK VALVE.

Mustang 9" Zinc Single Diaphragm Brake Booster (Includes Push Rod & Check Valve) is an exact duplicate of the original finsih and includes the pushrod boot and check already installed. The 9" booster requires 18" of vacuum to operate properly. With this vacuum level the booster will produce a maxium pressure output of 1100 psi with a 1" bore master cylinder. This pressure level will work great for disc/drum vehicles.

This booster is recommended for heavy disc brake cars like 55 chevy's or for street rods.
