Turn pedal effort into hydraulic braking pressure with the Dorman First Stop Brake Master Cylinder M630671, a new Honda Fit master cylinder that is a direct-fit replacement for the 2009-2014 Honda Fit and 2010-2014 Honda Insight (all engines). Dorman engineered it to match the original master cylinder's design, function and performance on the listed applications. It is built from new, high-quality materials.
A brake master cylinder converts the force at the brake pedal into hydraulic pressure. It sends that pressure through its two outlets and the brake lines to the wheels. If a worn or leaking master cylinder is the cause of a soft or sinking pedal, this unit replaces it.
Specifications: 1.063-inch bore diameter, two outlets, M12 x 1.0 rearward and secondary outlet threads, and a 1 mm primary outlet thread pitch. The package contains one master cylinder. The reservoir, sensor and mounting hardware are not included. Transfer or replace the reservoir and sensor as directed by the service procedure. Consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
