Dorman - First Stop Brake Master Cylinder P/N:M630126
$190.99
Turn brake-pedal effort into the hydraulic pressure that operates your brakes with the Dorman - First Stop Brake Master Cylinder (P/N M630126). It drops in as a direct-fit replacement for the 2000-2006 Toyota Tundra (All engines), engineered to match the design, function, and performance of the original master cylinder on the listed application.
- 100% new build: made entirely of new materials, not remanufactured.
- Durable EPDM seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- Cast aluminum housing: the aluminum cylinder housing is built to match the casting material of the original part for similar performance.
- Two outlets: primary and secondary M10 x 1.0 outlets (1 mm thread pitch) feed the brake circuits, with a 0.813 in bore.
A reservoir and a sensor are both included; mounting hardware is not — consult the vehicle service information for the correct fasteners and whether they may be reused. Made to meet rigorous SAE International standards. Signs the original master cylinder may need replacing include a brake pedal that slowly sinks under steady pressure, a spongy pedal, or fluid loss with no external leak; if a failed master cylinder is the cause, this replaces it. Country of origin: Taiwan.
