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.

  • Precise replacement: The aluminum cylinder housing is built to match the casting material of the original part, for similar performance.
  • Durable design: Every rubber component is made of high-quality EPDM compound for resistance to glycol-based brake fluid.
  • 100% new: The unit is made entirely from new materials, with quality and safety in mind.
  • Strict specifications: It is built to meet rigorous SAE International standards.

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.
