Product Details

The Dorman M390450 is a 100% new brake master cylinder engineered as a direct OE replacement for select Ford and Mercury vehicles. Unlike remanufactured units, this master cylinder is built entirely from new materials, delivering the quality and safety assurance that brake system components demand.

The cylinder housing is constructed to match the casting material of the original part, ensuring proper fit and consistent hydraulic performance. All internal rubber components are manufactured using high-quality EPDM compound, providing superior resistance to glycol-based brake fluids and long-term durability.

Key Features:

  • Precise OE Replacement – Housing is cast to match original specifications for correct fit and consistent brake performance
  • EPDM Rubber Components – All seals and rubber parts resist glycol-based brake fluid degradation
  • 100% New Construction – Built entirely from new materials; not remanufactured or rebuilt
  • SAE International Standards – Manufactured to meet rigorous SAE specifications for safety and reliability
  • Direct Bolt-On Installation – Engineered to match original mounting points and port configurations

The Dorman M390450 brake master cylinder is the trusted choice for repair professionals and DIY mechanics seeking a reliable, long-lasting replacement that restores full braking system confidence.

I called to see if it would ship before I needed it to go on a trip. I gave bad information about my order, but the employee went out of his way to track down my order and made sure that it went out ASAP. Thanks guys!!!<br><br>

This place was great. Great service they really helped mr out and were fast and extremely helpful.

I couldn't find this part anywhere! That's until I found Autoplicity! Thanks Guys!

Arrived in 4 business days and cheapest price on the web for the part I got.

Great prices! Wonderful customer service!

I ordered a rear sway bar for my MINI Cooper on Sunday and it was at my door on Wednesday! Autoplicity had the absolute cheapest price for this bar and I was very impressed with the shipping speed. I would definitely recommend them to my friends!

Fast shipping and a great product at an unbelievable price! Thanks!
