Convert brake-pedal force into the hydraulic pressure that operates both brake circuits with the Dorman First Stop Brake Master Cylinder M39408. It installs as a direct-fit replacement for the 1982-1983 Nissan 280ZX (All engines), engineered to drop in like the original master cylinder on this application.

  • Aluminum housing: constructed to match the casting material of the original part for similar performance.
  • EPDM rubber components: made of a high-quality EPDM compound for resistance to glycol-based brake fluid.
  • 100% new: made entirely of new materials, not remanufactured, and built to meet SAE International standards.
  • Configuration: two outlets, a 0.938 in bore, and M10 x 1.0 outlet threads; includes the reservoir and sensor. Mounting hardware is not included.

The master cylinder pressurizes brake fluid to your calipers and wheel cylinders each time you press the pedal. Signs this part may need replacing include a pedal that slowly sinks under steady pressure, a spongy or low pedal, or fluid seepage at the cylinder. If a failed master cylinder is the cause, this replaces it. Mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
