This brake master cylinder is precision-engineered to match the design, function, and performance of the original master cylinder on specific vehicle years, makes and models. It is made of new, high-quality materials for a safe, durable replacement.

Product Features:

Precise replacement – cylinder housing is constructed to match the casting material of the original part and ensure similar performance
Durable design – all rubber components are made of high-quality EPDM compound for resistance to glycol-based brake fluid
100% new – made entirely of new materials, not remanufactured, to ensure highest quality and safety
Strict specifications – made to meet rigorous SAE International standards

Using advanced re-engineering materials and processes, our master cylinders match O.E. performance and fitment. New O.E.-quality seals and cups are installed on each unit, ensuring leak-free, long-lasting performance. Cast-iron master cylinders are treate

Product Features:

Only new O.E.-quality seals and cups are used in the remanufacturing process to ensure O.E. performance and reliability. All rubber components meet S.A.E. specifications.
Bleeding kits are supplied with the unit to make the bleeding process faster and easier (where applicable).
Bores meet critical micro-finish specifications to eliminate pitting and corrosion, a cause of premature failure.
Cast-iron master cylinders feature a premium protective coating to minimize rust and extend unit life.
Piston assemblies are height-gauged to ensure the master cylinder equals the O.E. unit performance.
Plastic reservoirs are vacuum-tested to ensure they are leak free.
