Product Details

The Dorman M390179 is a direct-fit replacement brake master cylinder engineered to restore proper hydraulic pressure and braking performance. Designed as a 100% new unit—not remanufactured—it matches the original equipment specifications for a safe, reliable replacement.

Key Features:

  • Precise OE Replacement: Cylinder housing is constructed to match the casting material of the original part for accurate fit and similar performance
  • Durable Rubber Components: All seals and internal rubber parts are made from high-quality EPDM compound, providing excellent resistance to glycol-based brake fluids
  • 100% New Construction: Made entirely from new materials—never remanufactured—ensuring the highest levels of quality and safety
  • SAE Compliant: Manufactured to meet rigorous SAE International standards for hydraulic brake components
  • Integrated Reservoir: Includes a fluid reservoir, eliminating the need for separate fluid storage components

The Dorman M390179 brake master cylinder is the smart choice for restoring firm, confident brake pedal feel. It is designed for straightforward installation using standard brake system tools. Always bleed the brake system thoroughly after installation to purge air and ensure full hydraulic function.

Looked around online everywhere for my spark plug set. Autoplicity had what I wanted at the lowest price. Thanks guys!

I ordered street performance brake pads. Autoplicity had the best price on the net and were shipped quick. Can't wait to get them installed.

Fast, Professional and great prices.

Needed a pair of brake pads all the way around for my car, Autoplicity had the exact parts in stock and also the best price. Shipped same day. Very Pleased. Order # 19227

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.
