Turn brake-pedal effort into the hydraulic pressure that operates your brakes with the Dorman - First Stop Brake Master Cylinder M630298. It installs as a direct-fit replacement for the 2003-2008 Toyota Corolla [All] and 2003-2008 Toyota Matrix [All]. Dorman precision-engineers this unit to reproduce the design, function, and performance of the original master cylinder on these applications, using all-new materials for a durable service replacement.

  • Aluminum housing: the cylinder housing is built to match the casting material of the original part for similar performance.
  • 100% new: made entirely of new materials — not remanufactured.
  • EPDM rubber components: the rubber parts use a high-quality EPDM compound for resistance to glycol-based brake fluid.
  • Two outlets: features a 0.813 in bore and two outlets with M10 x 1.0 threads.

The fluid reservoir and fluid-level sensor are included; mounting hardware is not — consult the vehicle service information for the correct fasteners and whether they may be reused. Made to meet SAE International standards. Signs the original may need replacing include a sinking or spongy pedal or brake-fluid seepage; if a failed master cylinder is the cause, this replaces it. Diagnose the cause before replacing. Country of origin: Taiwan.
