Convert brake-pedal force into the hydraulic pressure your braking system depends on with the Dorman - First Stop Brake Master Cylinder M630299. It drops in as a direct-fit replacement for the 2003-2008 Toyota Corolla [All] and the 2003-2008 Toyota Matrix [All], and it arrives 100% new rather than remanufactured.

  • 100% new construction: built entirely from new, high-quality materials — not rebuilt — for a safe, durable replacement.
  • Aluminum housing: the cylinder housing is made to match the casting material of the original part for similar performance.
  • EPDM rubber components: the rubber parts use a high-quality EPDM compound that resists glycol-based brake fluid.
  • Built to spec: made to meet rigorous SAE International standards.

This master cylinder has a 0.813 in bore and two outlets, with an M10 x 1.0 rearward/secondary outlet and a 1 mm primary outlet thread pitch. The fluid reservoir and sensor are included; mounting hardware is not — 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 slowly sinking or spongy brake pedal, this replaces it; diagnose the cause before replacing. Country of origin: Taiwan.
