Assemblies match what was originally installed on the car from OE for quality, fit, function and material.

Product Features:

Rubber components independently tested and certified by approved labs globally to meet extreme (hi and low) temperatures.
Master cylinders use correct EPDM rubber for DOT3, 4 and 5 brake fluids
All aluminum castings are “hard anodized”
All iron castings are coated to prevent rust
Manufacturers all major components in house.
Most brake masters ship with OE size/shape reservoirs, floats, switches, sensors and valves to match original OE assembly.
All machining done by computer programed CNC machines.
Castings go through 2 inspection processes (via micrometer and via go-no go fixture check) before being sent to the assembly department insuring all machining is correct and matches the OE.
Before assembly all castings and components are cleaned by automated ultrasonic cleaning machines
Assembly is done in clean room insuring no contamination is introduced into final assembly.
All assemblies are dated coded for 100% accurate trace-ability.
Every assembly is pressure tested before being shipped insuring dependable operation and leak-free performance

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.
