Dorman - First Stop Brake Master Cylinder P/N:M390382

Turn every push of the brake pedal into steady hydraulic pressure with the Dorman - First Stop Brake Master Cylinder M390382. It drops in for the 1997-1998 Ford Mustang (All engines), converting pedal force into the fluid pressure that feeds the brake circuits. It is engineered to match the original master cylinder's design, function, and performance on the listed application.

• Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for similar performance.
• EPDM seals: all rubber components are made of a high-quality EPDM compound for resistance to glycol-based brake fluid.
• Two outlets: 1.063 in bore, with a rearward outlet sized M10 x 1.0 and a secondary outlet thread of M12 x 1.0.
• 100% new: made entirely of new materials — not remanufactured — and built to meet rigorous SAE International standards.

The reservoir and fluid-level sensor are included. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. If a leaking or internally bypassing master cylinder is behind a sinking or spongy pedal, this replaces it; diagnose the cause first. Country of origin: Taiwan.
