Generate the hydraulic pressure that operates the brakes with the Dorman - First Stop Brake Master Cylinder (M630296). When you press the pedal, the master cylinder converts that force into hydraulic pressure and sends it through two outlets to the brake circuits. It installs as a direct-fit replacement for the 2004 Acura TL [All] and 2003-2004 Honda Accord [All], precision-engineered to match the design, function, and performance of the original unit on these applications.

  • Aluminum housing: constructed to match the casting material of the original part for similar performance.
  • EPDM rubber components: all rubber parts use a high-quality EPDM compound for resistance to glycol-based brake fluid.
  • 100% new: made entirely of new materials, not remanufactured, and built to meet rigorous SAE International standards.
  • Specs: two outlets, 0.813 in bore diameter, and M14 x 1.5 outlet threads; reservoir and fluid-level sensor included.

Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
