• 100% new: built entirely from new materials, not remanufactured.
• Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for similar performance.
• Durable rubber: 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 two outlets, a 0.875 in bore diameter, and a rearward outlet sized M12 x 1.0 with a 1 mm primary outlet thread pitch. It ships as the master cylinder only — no reservoir, mounting hardware, or sensor is included, so transfer or source those as directed by the vehicle service procedure. Signs the original may need replacing include a sinking or spongy pedal, a pedal that slowly drops under steady foot pressure, and internal or external brake-fluid leaks; if a failed master cylinder is the cause, this replaces it. Country of origin: China.
