Dorman - First Stop Brake Master Cylinder P/N:M630574
$181.99
Turn the force from your brake pedal into the hydraulic pressure that operates the braking system with the Dorman – First Stop Brake Master Cylinder M630574. It's engineered to drop in like the original on the listed applications — a direct-fit replacement for the 2007-2010 Mazda 5 and the 2012 Mazda 5 (all engines). Precision-built to match the design, function, and performance of the factory master cylinder, it houses two outlets and a 0.875 in bore.
- Precise replacement: the aluminum cylinder housing is built to match the casting material of the original part for similar performance.
- Durable design: all rubber components use a high-quality EPDM compound to resist glycol-based brake fluid.
- 100% new: made entirely of new materials, not remanufactured, for consistent quality and safety.
- Strict specifications: made to meet rigorous SAE International standards.
Reservoir, sensor, and mounting hardware are not included. Consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
