Product Details

The Dorman M639008 is a 100% new brake master cylinder engineered as a direct replacement for select Chevrolet models. Unlike remanufactured units, this master cylinder is built entirely from new components, ensuring consistent performance and long-term reliability from day one.

The cylinder housing is constructed to match the casting material of the original equipment part, delivering an accurate, precise fit. All internal rubber components are manufactured using high-quality EPDM compound, specifically formulated for resistance to glycol-based brake fluids — helping prevent premature degradation and seal failure over time.

Key Features:

  • 100% new construction — not remanufactured, for maximum quality and safety
  • OE-matched housing — cylinder casting mirrors the original part for a direct-fit replacement
  • EPDM rubber internals — resistant to glycol-based brake fluid for long service life
  • SAE International standards — engineered and tested to meet rigorous industry specifications
  • Precision-engineered design — matches OEM dimensions for straightforward installation

Dorman's M639008 brake master cylinder delivers the confidence of OEM-quality engineering at an aftermarket value, making it a trusted choice for professional technicians and DIY installers alike.

I searched the internet high and low for the JKS Quicker Disconnects and almost thought it was a scam when I found them for this price! The order was simple and the shipping was fast. I could not be happier!

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere

Autoplicity had the best price anywhere! I looked everywhere for the airaid intake system and they had it in stock. Great company!

Excellent price on kirkey seats! I will be buying from them again. Thanks for the prompt service

Best prices on the web, shipping charges were as well, ordered on Tuesday received on Saturday of same week!!
