Dorman - First Stop Brake Master Cylinder P/N:M630650

Turn brake-pedal effort into the hydraulic pressure your Impala's brakes rely on with the Dorman - First Stop Brake Master Cylinder M630650. It's a direct-fit replacement for the 2009-2013 Chevrolet Impala (All) and 2014-2016 Chevrolet Impala Limited (All), engineered to reproduce the original master cylinder's design, function, and performance on these listed applications.

• 100% new build: made entirely of new materials — not remanufactured.
• Aluminum housing: the cylinder housing is built to match the original part's casting material for similar performance.
• EPDM seals: rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• SAE-spec engineering: made to meet rigorous SAE International standards.

This master cylinder has a 1-inch bore and two outlets, with an M14 x 1.5 secondary/rearward outlet thread and a 1.5 mm primary outlet thread pitch. 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 the original may need replacing include a pedal that slowly sinks under steady pressure, a spongy or fading pedal, or brake fluid leaking at the master cylinder. Country of origin: China.
