Product Details

The Dorman M390030 is a direct-fit replacement brake master cylinder engineered to restore proper braking system function. Precision-manufactured from 100% new materials, this master cylinder matches the design, dimensions, and performance of the original equipment part it replaces — no remanufactured cores, no compromises.

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 — ensuring the highest level of quality, reliability, and safety
  • SAE Compliant: Engineered to meet rigorous SAE International standards for brake system components
  • Direct-Fit Design: Bolt-on replacement that matches original mounting points, port locations, and reservoir configuration
