Product Details

The Dorman M39633 is a 100% new brake master cylinder engineered to restore proper hydraulic brake function. Built to meet or exceed original equipment specifications, this direct-fit replacement delivers consistent brake fluid pressure and reliable stopping power without the cost of a dealer part.

Unlike remanufactured units, the M39633 is made entirely from new materials, including a precision-cast cylinder housing and high-quality EPDM rubber internal components that provide excellent resistance to glycol-based brake fluids. The result is a durable, long-lasting replacement that installs like the original.

Key Features:

  • 100% New Construction — not remanufactured, ensuring highest quality and safety
  • Precision-Matched Housing — cylinder body is cast to match the material and dimensions of the original part
  • EPDM Rubber Components — internal seals and cups resist degradation from glycol-based brake fluid
  • SAE International Compliant — manufactured to meet rigorous SAE standards for hydraulic brake components
  • Direct-Fit Design — engineered for straightforward installation with no modifications required

The Dorman M39633 brake master cylinder is the dependable choice for both professional technicians and experienced DIYers looking for a quality OEM-style replacement backed by Dorman's engineering expertise.

Very easy to find products

Website is well organized.

Good prices, free shipping, easy to order, I like this place!

The shipping was fast, although I couldn't get it the first day because they require signature for delivery. I guess it's an added safety measure. Thank you! Will shop buy from again!
