Replace a leaking or worn master cylinder with the Dorman First Stop Brake Master Cylinder M32900, a new cast-iron unit that converts brake pedal force into the hydraulic pressure that operates your brakes. It fits many vehicles, among them the 1964-1965 Ford Mustang, the 1960-1963 Ford Country Squire and the 1960-1963 Ford Galaxie, all engines, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
Dorman precision-engineers this master cylinder to match the original unit's design, function and performance on the vehicles it is cataloged for. It is built from new, high-quality materials as a durable replacement. If you need a 1965 Mustang brake master cylinder, this one arrives with its reservoir included.

Signs a master cylinder may need replacing include a soft or sinking brake pedal, fluid seeping from the unit, or a brake fluid level that keeps dropping. Diagnose the cause before replacing, because leaking lines, hoses or wheel cylinders can produce similar symptoms.
