Frequently Asked Questions
What does the master cylinder do?
It converts force from the brake pedal into hydraulic pressure, sending that pressure through its two outlets to actuate the vehicle's brakes.
Which vehicles does M630665 fit?
It's a direct-fit replacement for the 2009 Ford Fusion, 2008-2009 Lincoln MKZ, and 2008-2009 Mercury Milan (All engines). Check the Buyer's Guide tab to confirm your vehicle.
Does it include a reservoir, sensor, or mounting hardware?
No. The package contains the master cylinder only; the reservoir, sensor, and mounting hardware are not included. Transfer or replace those as directed by the service procedure.
What is it made of?
The cylinder housing is aluminum, built to match the casting material of the original part, and the rubber components use an EPDM compound that resists glycol-based brake fluid.
What are signs the master cylinder may need replacing?
A pedal that slowly sinks under steady pressure, a soft or spongy pedal, or brake fluid loss around the cylinder can be signs. Diagnose the cause before replacing, since other parts can cause these.
