Dorman - First Stop Brake Master Cylinder P/N:M390185

Convert brake-pedal force into the hydraulic pressure that operates the brakes with the Dorman - First Stop Brake Master Cylinder (M390185). It drops in as a direct-fit replacement for the 1994-1996 Ford Mustang [All], engineered to match the design, function, and performance of the original master cylinder on those applications.

• 100% new: built entirely from new materials rather than remanufactured.
• Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for similar performance.
• Fluid-resistant seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• Built to standard: made to meet rigorous SAE International standards.

This master cylinder has a 1.063 in bore and two outlets — a rearward outlet sized M10 x 1.0 and a secondary outlet with an M12 x 1.0 thread diameter (1 mm primary outlet thread pitch). It ships with the reservoir and sensor included; 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. Signs the original may need replacing include a brake pedal that feels spongy or slowly sinks toward the floor and fluid seepage at the cylinder; diagnose the cause before replacing, and if a failed master cylinder is behind the symptom, this part replaces it.
