$186.99
Turn brake-pedal effort into the hydraulic pressure that operates the brakes with the Dorman - First Stop Brake Master Cylinder M630922. It drops in as a direct-fit replacement for the 2014-2019 Nissan Sentra [All], restoring the component that pressurizes the two brake circuits when you press the pedal. Dorman precision-engineers this cast iron unit to the design and function of the original on the listed applications, so it delivers similar performance without modification.
- Cast iron housing: constructed to match the casting material of the original part for comparable performance.
- EPDM rubber components: made from a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: built entirely of new materials, not remanufactured.
- Built to spec: made to meet rigorous SAE International standards.
This unit has a single integrated reservoir, an included fluid-level sensor, two outlets, and a 0.9375 in bore diameter, with M12 x 1.0 outlet threads at 1 mm pitch. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan. Signs the original master cylinder may need replacing include a sinking or spongy pedal and brake fluid leaks at the cylinder. If a failed master cylinder is the cause, this replaces it.
