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

from

$234.92

As the basis for a standardized ATE concept for future tandem master cylinders, ATE has developed a new plunger generation which has many technical enhancements and advantages.

Product Features:

Short closing paths
Low volume uptake
High efficiency
Low throttling / after-suction resistance
Low pressure differential between primary and secondary circuits
Good bleedability
Cr6-free surfaces for vehicles built from July 2007 (as required by law)
Central valve version suitable for ABS
Compact design – ideal for installation in small spaces
Reduced weight – by roughly 20% compared to conventional central valve technology
Fewer components – almost half as many as compared to conventional technologies
Modular system – diameters from 14.29 to 31.75mm and strokes up to 46mm
Low volume uptake – minimized elastic deformations due to smaller seals
Sealing cups supported in the housing – robustness against soiling and wear; longer life
