Quick facts
- Part: Dorman M630854 brake master cylinder
- Fits: 2011-2016 Jeep Grand Cherokee and other vehicles
- Material: Aluminum
- Condition: New
A soft or sinking brake pedal, brake fluid seeping at the cylinder or a brake warning light can mean the master cylinder is worn. Before replacing it, look with the engine off for wet spots along the brake lines and at the wheels, since a leak elsewhere gives a similar pedal. Have a weak pedal looked at promptly.
Fits
This master cylinder is a direct-fit replacement for the 2011-2016 Jeep Grand Cherokee and the 2011-2015 Dodge Durango.
