Product Details

The Dorman M630272 is a 100% new replacement brake master cylinder engineered to restore proper hydraulic braking pressure. Precision-designed to match the form, fit, and function of the original equipment part, this master cylinder delivers reliable, OEM-quality performance without the dealer price tag.

Key Features:

  • Precise OEM Replacement: Cylinder housing is constructed to match the casting material of the original part for comparable performance and fit
  • Durable EPDM Rubber Components: All internal rubber seals and components are made from high-quality EPDM compound, providing excellent resistance to glycol-based brake fluids
  • 100% New Construction: Made entirely from new materials—not remanufactured—ensuring the highest standard of quality and safety
  • SAE Compliant: Manufactured to meet rigorous SAE International specifications for hydraulic brake components
  • Direct Bolt-On Fit: Designed to install in the original mounting location with no modifications required

A failing brake master cylinder can cause a spongy brake pedal, brake fluid leaks, or illuminated dashboard warning lights. The Dorman M630272 provides a dependable, cost-effective solution that restores confident braking performance.
