Dorman - First Stop Brake Master Cylinder P/N:M39362

Keep hydraulic pressure flowing to every brake circuit with the Dorman - First Stop Brake Master Cylinder M39362. This master cylinder converts brake-pedal force into the hydraulic pressure that actuates the vehicle's braking system, and it's precision-engineered to match the design, function, and performance of the original unit — a direct-fit replacement for the 1981-1985 Mazda RX-7 (All engines).

• Cast iron housing: the cylinder housing is built 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.
• 100% new: made entirely of new materials, not remanufactured.
• Strict specifications: made to meet rigorous SAE International standards.

This unit has a 0.813 in bore and three outlets, and it ships with the reservoir included. The rearward and secondary outlet threads are M10 x 1.0, with a 1 mm primary outlet thread pitch. A sensor and mounting hardware are not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.

Signs a master cylinder may need replacing include a pedal that slowly sinks under steady foot pressure, a low or spongy pedal, or internal fluid leakage. If a failed master cylinder is the cause, this replaces it; diagnose the cause before replacing.
