Turn pedal effort into the hydraulic pressure your brakes depend on with a brand-new G6 master cylinder: the Dorman First Stop Brake Master Cylinder M630576. It is a direct-fit replacement for the 2008 Chevrolet Malibu (engine: All), the 2008 Pontiac G6 (engine: All) and the 2008 Saturn Aura (engine: All). Dorman engineered it to replicate the original master cylinder's design, function and performance on those vehicles.
- Precise replacement: The aluminum cylinder housing is built to match the original part's material for similar performance.
- Durable design: Every rubber component uses a high-quality EPDM compound that resists glycol-based brake fluid.
- 100% new: It is made entirely of new, high-quality materials and is intended to provide a safe, durable replacement.
- Strict specifications: It is made to meet rigorous SAE International standards.
Specifications: The bore diameter is 0.938 in., and the unit has two outlets. The rearward outlet size is M13 x 1.5, the secondary outlet thread diameter is M13 x 1.5, and the primary outlet thread pitch is 1.5 mm. 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. Country of origin: China.
Signs a master cylinder may need replacing include a soft or sinking brake pedal, brake fluid leaking at the cylinder, or a reservoir level that keeps dropping. Air or leaks elsewhere in the brake hydraulic system can produce similar signs, so diagnose the cause before replacing parts.
