Dorman - First Stop Brake Master Cylinder P/N:M96583
$143.99
Turn pedal effort into the hydraulic pressure your brakes depend on with the Dorman - First Stop Brake Master Cylinder M96583. It drops in as a direct-fit replacement for the 1975 Nissan 260Z and the 1975-1978 Nissan 280Z (engine: All), pressurizing brake fluid and pushing it out to the wheel circuits each time you press the pedal.
- 100% new build: made entirely of new materials, not remanufactured.
- EPDM seals: rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- Aluminum housing: aluminum body with a 0.875 in bore and two outlets; the casting material is matched to the original part for similar performance.
- Built to spec: manufactured to meet rigorous SAE International standards.
The rearward/secondary outlet uses an M10 x 1.0 thread, with a 1 mm primary outlet thread pitch. A reservoir is included; no sensor and no mounting hardware are supplied — consult the vehicle service information for the correct fasteners and whether they may be reused. Signs the original master cylinder may need replacing include a sinking or spongy pedal, internal or external fluid leaks, and reduced braking; if a failed master cylinder is the cause, this unit replaces it. Country of origin: Taiwan.
