Dorman - First Stop Brake Master Cylinder P/N:M390525

Send firm, consistent hydraulic pressure to every wheel brake with the Dorman - First Stop Brake Master Cylinder (M390525). The master cylinder converts the force from your brake pedal into the hydraulic pressure that operates the wheel brakes, so a sinking or spongy pedal, a pedal that slowly drops to the floor, or brake-fluid leakage are common signs this component may need replacing. It drops in as a direct-fit replacement for the 1999-2004 Ford Mustang [All].

• 100% new: built entirely from new materials — not remanufactured.
• Aluminum housing: the cylinder housing is cast to match the casting material of the original part for similar performance.
• Durable EPDM seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• Strict specifications: made to meet rigorous SAE International standards.

Specs: 1 in bore diameter, 2 outlets, with a rearward/secondary outlet thread of M10 x 1.0 (1 mm pitch). The reservoir and sensor are included; mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
