Dorman - First Stop Brake Master Cylinder P/N:M390513

Deliver the hydraulic pressure your brakes rely on with the Dorman - First Stop Brake Master Cylinder M390513, a direct-fit replacement for the 1999-2000 Mazda Miata [All]. The master cylinder converts brake-pedal force into the hydraulic pressure that operates the vehicle's brakes, so a healthy unit is essential to consistent pedal feel. This one is built with an aluminum housing, carries a 0.875 in bore, and features two outlets sized M10 x 1.0.

• 100% new: made entirely from new materials, not remanufactured.
• EPDM rubber components: the rubber parts use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• Aluminum housing: the cylinder housing is constructed to match the casting material of the original part.
• Built to spec: made to meet rigorous SAE International standards.

The reservoir and sensor are included; mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Signs this part may need replacing include a brake pedal that slowly sinks to the floor, a spongy pedal, or brake-fluid loss with no external leak; if a failed master cylinder is the cause, this replaces it. Country of origin: Taiwan.
