Dorman - First Stop Brake Master Cylinder P/N:M39403
Dorman M630266 brake master cylinder for the 2000-2002 Ford E-450 Econoline Super Duty and other vehicles turns pedal force into hydraulic pressure for the brakes. This Dorman brake master cylinder is made entirely of new materials.
A brake pedal that feels soft or sinks, or fluid around the cylinder, can mean the master cylinder is wearing out. Worn brake hoses, a leaking caliper or a weak brake booster can be behind the same signs, so find the cause before you buy. A brake system needs just one master cylinder, and this listing is one.
This brake master cylinder is a direct-fit replacement for the 2000-2002 Ford E-450 Econoline Super Duty, the 1999-2001 Ford E-350 Econoline Club Wagon and the 1999-2001 Ford E-350 Super Duty. If your vehicle is not named here, look up its year, make and model in the "Vehicles it fits" section before you order.
