Turn pedal effort into the hydraulic pressure your brakes rely on with the Dorman - First Stop Brake Master Cylinder M630802. It drops in as a direct-fit replacement for the 2010-2015 Subaru Legacy [All] and 2010-2014 Subaru Outback [All], generating the fluid pressure that pushes brake fluid out to the wheel circuits when you press the pedal.

  • Aluminum housing: constructed to match the casting material of the original part for similar performance.
  • EPDM rubber components: made from a high-quality EPDM compound for resistance to glycol-based brake fluid.
  • 100% new: built entirely of new materials, not remanufactured, and made to meet SAE International standards.
  • Ready to plumb: single reservoir type with reservoir and sensor included, two outlets, a 0.938 in bore, and M12 x 1.0 (1 mm pitch) outlet threads.

Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. A sinking or spongy pedal, brake fluid leakage at the cylinder, or an illuminated brake warning are signs the original master cylinder may need replacing — if a failed master cylinder is the cause, this unit replaces it. Country of origin: Taiwan.
