Turn brake-pedal effort into the hydraulic pressure that applies the brakes with the Dorman First Stop Brake Master Cylinder, MPN M630476. It installs as a direct-fit replacement for the 2005-2010 Scion tC (All engines), pressurizing the brake circuits through its two outlets when you press the pedal.

Dorman precision-engineers this unit to the design and function of the original master cylinder for the listed applications and builds it to SAE International standards.

  • Aluminum housing: cast to match the casting material of the original part for similar performance.
  • 100% new: made entirely of new materials, not remanufactured.
  • EPDM rubber components: made of a high-quality EPDM compound that resists glycol-based brake fluid.
  • Specs: two outlets, 0.813 in bore diameter, secondary/rearward outlet M10 x 1.0.

Mounting hardware, reservoir, and sensor are not included — the package contains the master cylinder only. If a failed master cylinder is the cause of a sinking pedal or loss of braking pressure, this replaces it; diagnose the cause before replacing. Country of origin: China.
