Dorman - First Stop Brake Master Cylinder P/N:M390268

Convert brake-pedal force into the hydraulic pressure that operates your brakes with the Dorman - First Stop Brake Master Cylinder M390268. It's a direct-fit replacement for the listed applications: the 1995-1997 Ford Explorer and Ford Ranger, the 1995-1997 Mazda B2300, B3000, and B4000, and the 1997 Mercury Mountaineer (all engines). Dorman engineers this unit to match the design, function, and performance of the original master cylinder on those vehicles.

• 100% new: made entirely from new materials rather than remanufactured, for consistent quality and safety.
• 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.
• Built to spec: made to meet SAE International standards; features a 1.063 in bore, two outlets, and includes a reservoir and sensor.

The master cylinder draws brake fluid from the reservoir and forces it through its two outlets to the brake circuits when you press the pedal. If a failed master cylinder is the cause, signs such as a sinking or spongy pedal or internal/external fluid leaks may indicate it needs replacing; diagnose the cause first. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
