$147.99
Deliver hydraulic pressure to both brake circuits with the Dorman - First Stop Brake Master Cylinder M630478, a direct-fit replacement for the 2005-2007 Toyota Tacoma [All]. A master cylinder turns brake-pedal force into the fluid pressure that operates the braking system; this unit is precision-engineered to replicate the design, function, and performance of the factory master cylinder on the listed application.
- 100% new: built entirely from new materials — not remanufactured.
- Durable design: rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- Precise replacement: the aluminum cylinder housing is built to match the casting material of the original part for similar performance.
- Built to spec: made to meet rigorous SAE International standards.
It features a 1.625 in bore and two outlets with M10 x 1.0 threads, and ships with the reservoir and fluid-level sensor included. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. If a failed master cylinder is the cause of a sinking or spongy brake pedal, this replaces it; diagnose the cause before replacing. Country of origin: China.
