Turn every press of the brake pedal into hydraulic pressure for your brakes with the Dorman First Stop Brake Master Cylinder M630920. This new master cylinder is a direct-fit replacement for the 2013-2018 Nissan Pathfinder, the 2014-2017 Infiniti QX60 and the 2013 Infiniti JX35. Dorman designed it to replicate the original master cylinder's design, function and performance on the listed applications, and built it from new, high-quality materials for a safe, durable replacement.
- Precise replacement: the cylinder housing is cast iron, matching the casting material of the original part for similar performance.
- Durable design: every rubber component is made of high-quality EPDM compound, which resists glycol-based brake fluid.
- 100% new: made entirely of new materials for quality and safety.
- Strict specifications: built to meet rigorous SAE International standards.
Specifications: cast-iron body, 1.0625-inch bore, two outlets, M12 x 1.0 rearward and secondary outlet threads, 1 mm primary outlet thread pitch. The package contains the master cylinder only. The reservoir, sensor and mounting hardware are not included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
A soft or sinking pedal, or fluid seeping from the cylinder, are signs a master cylinder may need replacing. Diagnose the cause first, and follow the vehicle's service procedure for installation and bleeding.
