Product Details

The Dorman M631044 is a 100% new replacement brake master cylinder, precision-engineered to match the design, function, and performance of the original equipment component. Unlike remanufactured alternatives, this unit is built entirely from new materials to deliver the highest levels of quality, safety, and long-term reliability.

Key Features:

  • Precise OEM Replacement: Cylinder housing is constructed to match the casting material of the original part for equivalent fit and performance
  • Durable EPDM Rubber Components: All internal rubber seals and components are made from high-quality EPDM compound, engineered for resistance to glycol-based brake fluids
  • 100% New Construction: Not remanufactured — every component is new, eliminating the risk of wear or contamination from previously used parts
  • SAE Compliant: Manufactured to meet rigorous SAE International standards for performance and safety
  • Sold Without Reservoir: Direct-fit replacement cylinder body; reuses the existing reservoir

Dorman has been a trusted name in the automotive aftermarket for over a century, offering OEM-quality replacement parts that give technicians and vehicle owners a reliable, cost-effective repair solution.
