Product Details

The Dorman M39705 is a 100% new OEM-replacement brake master cylinder engineered to restore proper braking system function. Unlike remanufactured units, this master cylinder is built entirely from new materials, delivering the reliability and safety expected from a critical brake system component.

Key Features:

  • Precise OEM replacement — cylinder housing is constructed to match the casting material of the original part for equivalent performance
  • EPDM rubber components — all internal seals and rubber parts use high-quality EPDM compound for superior resistance to glycol-based brake fluids
  • 100% new construction — not remanufactured or rebuilt; made entirely of new materials for maximum quality and safety
  • SAE International standards — manufactured to meet rigorous SAE specifications for brake system components
  • Direct-fit design — engineered to match the form, fit, and function of the original master cylinder for a straightforward installation

Dorman has been a trusted name in the automotive aftermarket for over 100 years, offering OE-quality replacement parts designed to save time and reduce repair costs. The M39705 brake master cylinder is the dependable, new-part alternative to costly dealer-sourced replacements.

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!

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.

Great prices

Great prices and very quick shipping! Thanks
