Product Details

The Dorman M630125 is a 100% new OE replacement brake master cylinder engineered to restore proper hydraulic braking function. Built to match the original equipment design in form, fit, and function, this master cylinder features a 1.000-inch bore, dual outlet ports, and is power brake compatible — making it a direct drop-in replacement for the failed or leaking original unit.

Key Features:

  • OE-matched housing — cylinder body is constructed to match the casting material of the original part for consistent performance
  • EPDM rubber seals — all internal rubber components use high-quality EPDM compound for superior resistance to glycol-based brake fluid
  • 100% new construction — manufactured entirely from new materials, not remanufactured, for maximum reliability and safety
  • SAE International standards — engineered and tested to meet rigorous SAE specifications
  • Power brake compatible — designed for use with power brake booster systems
  • Dual outlet ports — supports split hydraulic brake circuits as required by the original application

Dorman's First Stop brake master cylinders undergo strict quality control to ensure each unit meets or exceeds OEM performance requirements. Installing a fully new master cylinder — rather than a remanufactured unit — eliminates concerns about worn bores, compromised seals, or residual fluid contamination from the old part.

On Monday I placed an order for a Moroso Battery Switch (which was competitively priced BTW) and sitting here Wed afternoon I've got my switch in hand. Autoplicity was perfect every step of the way, including immediate notification of the order receipt, notification of shipment, even notification that it had been delivered (and it was waiting on my front porch). Packing was suitable too. Couldn't be happier. Buy with confidence. Kev

Great to order via Amazon; don't need to remember another account and password.

Quick turnaround and the best prices on the web!

Excellent prices, inventory and fast service. I placed my order on Saturday, Aug 4, it was shipped on Monday, Aug 6, and due to arrive on Friday. I will be a repeat customer with prices and service like this.

Very good price on k&n air filter, will definitely order from autoplicity again.

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

I did a price comparison for hard-to-find Redline motor and tranmission oil of over 30 different vendors and websites through Amazon, E-bay, Google, etc. and Autoplicity had the best price by 25-30%. It was a no-brainer to order from them, and their website is easy search and manage. And their shipping charges aren't too bad either.
