The Dorman - First Stop Brake Master Cylinder (M630506) converts brake-pedal force into the hydraulic pressure that operates the vehicle's brake circuits, feeding two separate outlets. It drops in for the 2007-2009 Chevrolet Equinox, 2007-2009 Pontiac Torrent, 2008-2010 Saturn Vue, and both the 2008-2009 and 2012-2015 Chevrolet Captiva Sport [All].

  • 100% new: made entirely of new materials, not remanufactured.
  • Aluminum housing: constructed to match the casting material of the original part for similar performance.
  • Durable design: rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
  • Strict specifications: made to meet rigorous SAE International standards.

This unit is precision-engineered to match the design, function, and performance of the original master cylinder on the listed applications. It has a 1-inch bore and two outlets, with an M12 x 1.0 rearward outlet and a 1 mm primary outlet thread pitch. The package contains the master cylinder only — a reservoir, mounting hardware, and sensor are not included, so transfer or source those as directed by the vehicle service procedure. If a failed master cylinder is the cause of a sinking or spongy pedal, this replaces it. Country of origin: China.
