Product Details

The Dorman M390218 is a 100% new brake master cylinder engineered as a direct OE replacement. Unlike remanufactured units, this cylinder is built entirely from new materials, ensuring consistent hydraulic performance and long-term reliability right out of the box.

The cylinder housing is constructed to match the casting material of the original part, delivering the same fit, form, and function as the factory unit. All internal rubber components are made from high-quality EPDM compound, providing superior resistance to glycol-based brake fluids and extending service life.

Key Features:

  • 100% new construction — not remanufactured, for highest quality and safety
  • Precision-matched housing — cast to mirror the OEM part's design and material
  • EPDM rubber components — resistant to glycol-based brake fluid degradation
  • SAE International standards — engineered and tested to meet rigorous industry specifications
  • Direct-fit replacement — matches OEM mounting points and brake line connections

Proper brake system bleeding is recommended after installation to purge air and restore full hydraulic pressure. The Dorman M390218 is the trusted choice for restoring safe, confident braking performance.

great price and customer service

Great price and quick shipping!

Excellent service!!!! Ordered another part from one of those big chain stores three days earlier and got your part one day sooner than theirs. Thanks. Excellent customer service. Wouldn't hesitate to use you again.

Great product and speedy service!

Couldn't be more happy with my product. I ordered from Autoplicity because they were the cheapest price around and I received my order within 5 days. I have installed the cold air intake and couldn't believe all the extra power. I am very pleased with the entire transaction.
