Product Details

The Dorman M390129 is a 100% new replacement brake master cylinder engineered to restore proper hydraulic pressure and pedal feel to your vehicle's braking system. Unlike remanufactured alternatives, this unit is built entirely from new materials, ensuring consistent quality and long-term reliability right out of the box.

Key Features:

  • Precise OE Replacement – Cylinder housing is constructed to match the casting material of the original part for accurate fit and similar performance
  • 100% New Construction – Made entirely of new materials, not remanufactured, for the highest level of quality and safety
  • Durable EPDM Seals – All rubber components use high-quality EPDM compound formulated for resistance to glycol-based brake fluids
  • SAE-Compliant – Engineered to meet rigorous SAE International standards for hydraulic braking components
  • Direct-Fit Design – Matches the OEM mounting configuration for straightforward installation

The Dorman M390129 is a dependable, cost-effective solution for vehicles suffering from a soft brake pedal, internal cylinder leaks, or worn seals. Bleed the brake system thoroughly after installation to purge air and restore full hydraulic function.
