Dorman - First Stop Brake Master Cylinder P/N:M630623
Turn every push of the brake pedal into hydraulic pressure with a new 2000-2002 Nissan Frontier master cylinder: the Dorman First Stop Brake Master Cylinder M630102. It sends that pressure to the brakes through two outlets and is a direct-fit replacement for the 2000-2002 Nissan Frontier (all engines).
This 2000-2002 Nissan Frontier brake master cylinder is precision-engineered to mirror the design, function and performance of the original master cylinder on the listed trucks. It is built from new, high-quality materials for a safe, durable replacement.
Specifications: 1-inch bore diameter; two outlets; M10 x 1.0 rearward outlet size; M10 x 1.0 secondary outlet thread diameter; 1 mm primary outlet thread pitch. The reservoir is included. A sensor and mounting hardware are not included. Country of origin: Taiwan.
If a worn master cylinder is the cause of a soft or sinking pedal, this unit replaces it. Diagnose the brake system first. After installation, bleed the brakes as the vehicle service procedure directs.
