Description

Turn firm pedal pressure into the hydraulic force that works your brakes with the Dorman - First Stop Brake Master Cylinder M630613. It drops in as a direct-fit replacement for the 2009-2013 Mazda 6 [All], converting brake-pedal effort into fluid pressure sent through its two outlets to the brake system.

100% new: built entirely from new materials, not remanufactured.
Aluminum housing: the cylinder housing is cast to match the casting material of the original part for similar performance.
EPDM rubber components: made of a high-quality EPDM compound for resistance to glycol-based brake fluid.
SAE International standards: made to meet these rigorous specifications.

Key specs: aluminum master cylinder with a 0.875 in bore, two outlets, and M10 x 1.0 outlet threads (1 mm primary outlet thread pitch). Mounting hardware, reservoir, and sensor are not included — consult the vehicle service information for the correct parts and procedure. If a failed master cylinder is the cause of a sinking pedal or spongy brakes, this replaces it; diagnose the cause first, as those signs can have other sources. Country of origin: Taiwan.
