Turn brake-pedal effort into the hydraulic pressure your braking system relies on with the Dorman First Stop Brake Master Cylinder M630108, engineered to drop in on the 1999-2004 Honda Odyssey (All engines). Dorman precision-engineers this unit to match the design, function, and performance of the original master cylinder for these listed applications, so it installs as a direct-fit replacement.

  • Aluminum housing: built to match the casting material of the original part for similar performance.
  • EPDM rubber components: made of a high-quality EPDM compound for resistance to glycol-based brake fluid.
  • 100% new: made entirely of new materials, not remanufactured, and made to meet rigorous SAE International standards.
  • Specs: 27 mm bore with two outlets (M12 x 1.0 threads); reservoir and sensor included; mounting hardware not included.

The master cylinder converts the force from your brake pedal into hydraulic pressure that pushes fluid to the wheel circuits. If a failed master cylinder is the cause of a sinking pedal or internal fluid bypass, this replaces it. Since mounting hardware is not included, consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
