Product Details

The Dorman M39658 is a direct-fit replacement brake master cylinder engineered to restore proper braking system function. Constructed to match the casting material and geometry of the original equipment part, this master cylinder delivers the same pedal feel and hydraulic performance as the factory unit.

Unlike remanufactured units, the M39658 is built entirely from new components, ensuring consistent quality and long-term reliability. All internal rubber seals and components are manufactured from high-grade EPDM compound, providing superior resistance to glycol-based brake fluids and helping prevent premature degradation.

Key Features:

  • Precise OE replacement — cylinder housing matches original casting material for accurate fit and performance
  • 100% new construction — not remanufactured, ensuring the highest standards of quality and safety
  • EPDM rubber components — resistant to glycol-based brake fluid for extended service life
  • Meets SAE International standards — manufactured to rigorous industry specifications
  • Drop-in installation — designed to align with factory mounting points and brake line connections

The Dorman M39658 brake master cylinder is the dependable, cost-effective alternative to an OEM dealer replacement, giving both professional technicians and DIY installers confidence in every brake repair.
