$201.99

The Dorman First Stop Brake Master Cylinder M39795 converts the force from your brake pedal into the hydraulic pressure that operates the braking system, and it's engineered to drop in like the original master cylinder on the 1988-1990 Nissan Pathfinder [All]. Signs the original may need replacing include a pedal that slowly sinks under steady foot pressure, a spongy or inconsistent pedal, or fluid seepage at the cylinder.

  • 100% new: made entirely of new materials, not remanufactured.
  • Aluminum housing: constructed to match the casting material of the original part for similar performance.
  • Durable design: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
  • Strict specifications: made to meet rigorous SAE International standards.

It has three outlets, a 0.938 in bore, and M10 x 1.0 outlet threads, and it ships with the reservoir and fluid level sensor included. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
