Quick facts
- Part: Dorman M631050 brake master cylinder
- Fits: the 2015-2020 Jeep Renegade and other vehicles
- Material: Aluminum
- Condition: New
A soft or sinking brake pedal, fluid around the cylinder or a brake warning light can mean the master cylinder is wearing out. Before you replace it, rule out leaks at the brake lines, calipers or wheel cylinders, because a new master cylinder will not cure a leak somewhere else. A car takes one master cylinder, and this listing is one.
