When a worn master cylinder leaves the brake pedal soft or sinking, this Dorman brake master cylinder M630625 from the First Stop line is designed to take its place. It is a direct-fit replacement for the 2009-2014 Ford E-150, 2009-2014 Ford E-250, 2009-2014 and 2016-2017 Ford E-350 Super Duty, 2009-2013 and 2016 Ford E-450 Super Duty, and the 2014 Ford Econoline Van and 2014 Ford Econoline Wagon (All engines).
A master cylinder converts brake-pedal force into hydraulic pressure for the brake system.
