Product Details

The Dorman M630652 is a 100% new brake master cylinder engineered as a direct OEM replacement. Precision-designed to match the fit, form, and function of the original unit, this master cylinder restores proper hydraulic braking performance without the expense of a dealer part.

Key Features:

  • Precision-matched housing — cylinder body is constructed to match the casting material of the original part for accurate fitment and reliable performance
  • EPDM rubber components — all internal seals and rubber parts are made from high-quality EPDM compound, providing resistance to glycol-based brake fluid
  • 100% new construction — not remanufactured; built entirely from new materials to ensure the highest levels of safety and quality
  • SAE-compliant — manufactured to meet rigorous SAE International engineering standards
  • 1-inch bore diameter — matches original specifications for consistent brake pedal feel and hydraulic pressure
  • ASE-certified support — backed by Dorman's in-house ASE Certified technical support team

Dorman is a US-based automotive parts manufacturer headquartered in Colmar, Pennsylvania, with over a century of experience in aftermarket solutions. The M630652 delivers OEM-quality braking performance at an aftermarket price point, making it a trusted choice for professional technicians and DIY installers alike.

Quick easy fair price

thanks

Very good service, product arrived promptly.

good customer service. after shopping around for a while i decided to go with them.

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Fast and easy !

Autoplicity had the best price on the item on the ski rack I needed! I ordered it on a Friday and it was delivered the following Wednesday.

groovy

Same product as others with better price. Simple and easy to buy products on website and good shipping.
