Product Details

The Dorman M39950 is a direct-fit replacement brake master cylinder engineered to restore proper braking system function. Precision-manufactured to match the original equipment design, this master cylinder delivers the same fit, form, and performance as the factory unit it replaces.

Key Features:

  • Precise OE Replacement: Cylinder housing is constructed to match the casting material of the original part for consistent performance and direct bolt-on fitment
  • Durable EPDM Rubber Components: All internal seals and rubber parts are made from high-quality EPDM compound, providing excellent resistance to glycol-based brake fluid
  • 100% New Construction: Made entirely from new materials — not remanufactured — ensuring the highest levels of quality, reliability, and safety
  • SAE International Compliant: Manufactured to meet rigorous SAE International standards for brake system components

The Dorman M39950 brake master cylinder is an ideal solution for restoring confident, reliable braking performance without the variability of remanufactured parts.
