Product Details

The Dorman M390276 is a 100% new replacement brake master cylinder engineered to restore proper hydraulic braking performance. Unlike remanufactured units, this master cylinder is built entirely from new components, 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
  • Durable EPDM Rubber Components: All internal seals and rubber parts are made from high-quality EPDM compound, providing superior resistance to glycol-based brake fluids
  • 100% New Construction: Made entirely of new materials — not remanufactured — to ensure the highest standards of safety and reliability
  • SAE Compliant: Manufactured to meet rigorous SAE International standards for brake system components
  • Direct-Fit Design: Engineered to match the original master cylinder's form, function, and mounting configuration for a straightforward installation

The Dorman M390276 brake master cylinder is the trusted choice for technicians and DIYers who need a dependable, new-condition replacement without compromise. Proper brake system bleeding after installation is recommended to ensure full hydraulic function.

I searched the entire web looking for the best price on my item and found that Autoplicity beat everybody else in price & quality. Search no more!

Best price I could find on the net and super fast shipping.

Autoplicity had the best price on the VP fuel jugs, I ask if the could ship them out quickly and they did.

I ordered a new battery for my Harley. I wanted a battery that would last and be of good quality. I bought a Odyssey PC545 battery it stats stat it will last up to 8 years and is military grade. My package arrived quick and in good shape. My order number is #5600. Thanks

Cheapest I could find anywhere !!!

i was skeptical about this site but after reading the reviews and them having the lowest price i could find for my part i pulled the trigger and wasn't disappointed. fast shipping and low prices with great customer service will shop with them again if they have what im looking for.

I placed an order,18852,for a Husky Liner on June 19th and received it on June 21st. They have a great price and low cost shipping.

Quick shipping, good communication, low price, would purchase again from this company.
