Description

Convert brake-pedal effort into the hydraulic pressure that operates the brakes with the Dorman - First Stop Brake Master Cylinder M630597. Precision-engineered to match the design, function, and performance of the original unit, it installs as a direct-fit replacement on the 2008-2010 and the 2014-2018 Toyota Tacoma [All] — note these are two separate year ranges.

100% new build: made entirely of new materials rather than remanufactured, and manufactured to meet rigorous SAE International standards.
Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for similar performance.
EPDM seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
Ready to install: includes the fluid reservoir and fluid-level sensor; 0.813 in bore diameter with two outlets (M12 x 1.0 thread).

Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
