Description

Convert brake-pedal force into the hydraulic pressure that feeds both brake circuits with the Dorman - First Stop Brake Master Cylinder M630753. It drops in as a direct-fit replacement for the 2000-2003 Chevrolet Malibu, 2000-2004 Oldsmobile Alero, 2000-2005 Pontiac Grand Am, and 2004-2005 Chevrolet Classic (all engines). Dorman precision-engineers this unit to reproduce the original master cylinder's design, function, and performance on the covered applications.

Precise replacement: aluminum housing built to match the casting material of the original part for similar performance.
Durable design: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
100% new: made entirely from new materials, not remanufactured.
Built to spec: made to meet rigorous SAE International standards.

The dual-outlet design uses a 24 mm bore, with both the primary and secondary outlets threaded M10 x 1.0 (1 mm pitch). A fluid reservoir and a sensor are included; mounting hardware is not, so consult the vehicle service information for the correct fasteners and whether they may be reused. If a failed master cylinder is the cause of a sinking or spongy brake pedal, this unit replaces it. Country of origin: China.
