Product Details

The Dorman M390092 is a 100% new replacement brake master cylinder featuring a 0.875-inch bore and aluminum construction. Engineered to deliver the same fit, form, and function as the original equipment component, this master cylinder restores proper braking feel and hydraulic performance without the uncertainty of a remanufactured unit.

Dorman's First Stop brake line is built to meet SAE International standards, ensuring consistent quality and safety. The aluminum cylinder housing is cast to match the original part's specifications, while all internal rubber components use a high-quality EPDM compound formulated for long-term resistance to glycol-based brake fluids.

Key Features:

  • 0.875 in. bore aluminum construction for precise hydraulic actuation
  • Cylinder housing cast to match the original part's material and geometry
  • EPDM rubber seals and components resist degradation from glycol-based brake fluid
  • 100% new — not remanufactured — for maximum reliability and safety
  • Built to meet rigorous SAE International standards
  • Direct OE-style replacement for a straightforward installation

As a brand-new unit, the Dorman M390092 eliminates concerns about worn bores or aged seals common in remanufactured alternatives, making it a dependable choice for restoring full braking system integrity.

Did an extensive search on line to find the best price available, and autoplicity was definitely the best. Now I no longer need to spend more time searching, I will go straight to autoplicity!

Wow, Impressive delivery! It got here quicker than expected and Autoplicity actually carried what I was looking for.<br><br>Thank You Autoplicity!

My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

Very happy with the speed of shipping and with the reasonable price of the product.

Great prices for the parts I needed to replace on my SUV, a bit hard to reach customer service when I had a question about the order. When I finally did reach CS, question was answered without any issues, shipping costs seem a bit high.

Shipped ultra fast and had great prices!

Great prices and very quick shipping! Thanks
