Product Details

The Dorman M630009 is a direct-fit replacement brake master cylinder engineered to restore safe, reliable braking performance. Precision-designed to match the original equipment specifications, this master cylinder delivers the same fit, form, and function as the factory part — without the dealership price tag.

Key Features:

  • Precise OE Replacement: Cylinder housing is constructed to match the casting material of the original part for consistent, reliable performance
  • Durable EPDM Rubber Components: All internal rubber seals and components are made from high-quality EPDM compound, providing excellent resistance to glycol-based brake fluids
  • 100% New Construction: Built entirely from new materials — not remanufactured — ensuring maximum quality, safety, and longevity
  • SAE-Compliant: Manufactured to meet rigorous SAE International standards for hydraulic brake system components
  • Direct-Fit Design: Engineered to install without modification, simplifying the replacement process for technicians and DIY installers alike

As a critical hydraulic component in the braking system, the brake master cylinder converts pedal force into hydraulic pressure to actuate the brakes. When the original unit develops leaks, soft pedal feel, or fluid loss, a quality replacement like the Dorman M630009 restores proper braking response and driver confidence.

I recently ordered 2 Borla Dual Round Intercooled Tips from Autoplicity.com for one reason and reason only...their prices can not be beat! No where else online can anyone match them! <br>

Was looking online for the best price on a part and found that autoplicity had the lowest price and free shipping on it. I ordered it and it was shipped the next day along with tracking number. I will be ordering a few more parts from autoplicity. Order Number: 27769

easy and inexpensive!

The cheapest price on the net and very fast shipping. I received my items in 3 days and they were delivered on a Saturday to make things even better. <br><br>Will be using these guys again real soon.

Dont know yet. Hope item is in stock.

** Update 4/18/2012<br>Everything arrived in several different shipments. I did experience a problem with some FelPro Headbolts that I had ordered. I ordered two and only received one, but after a short phone call with Paul from shipping, the problem was fixed and my second set of bolts were shipped.<br><br>They had the cheapest price that I could find on several products. I did not like the order confirmations on there website as I had to copy and paste to search for my tracking number. I am supposed to receive my order today and I am scared because the two weights do not match up. Autoplicity says 37.7 pounds and fedex says 3.8 pounds. Maybe there is more than one tracking number and I just do not know.
