Dorman - First Stop Brake Master Cylinder P/N:M630373

Convert brake-pedal effort into the hydraulic pressure that operates the brake circuits with the Dorman - First Stop Brake Master Cylinder M630373. It installs as a direct-fit replacement for the 2002-2008 MINI Cooper (All engines), built to perform like the factory master cylinder it replaces.

• Aluminum housing: the cylinder housing is built to match the casting material of the original part for similar performance.
• Dual outlets: two outlets with M12 x 1.0 threads (1 mm primary outlet thread pitch) and a 0.875 in bore diameter.
• Durable rubber: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• 100% new: made entirely of new materials, not remanufactured, and made to meet rigorous SAE International standards.

This listing is for the master cylinder only — no reservoir, sensor, or mounting hardware is included. Consult the vehicle service information for the correct fasteners and whether they may be reused. Signs this part may need replacing include a sinking or spongy brake pedal or unexplained fluid loss; if a failed master cylinder is the cause, this replaces it. Country of origin: Taiwan.
