Quick facts
- Part: Dorman M630063 brake master cylinder
- Fits: 2002-2006 Ford Expedition and other vehicles
- Material: Aluminum
- Condition: New
A brake pedal that sinks or feels soft, fluid on the cylinder body or a brake warning light can mean the master cylinder is wearing out. These signs alone do not prove it is the problem, since a leaking brake line can also leave the pedal low. If the master cylinder is the cause, this unit replaces it.
Fits
It is a direct-fit replacement for the 2002-2006 Ford Expedition, the 2002-2006 Lincoln Navigator and the 2003-2004 Lincoln Aviator. It is engineered to follow the original master cylinder's design, function and performance on these vehicles.
