Dorman - First Stop Brake Master Cylinder P/N:M390096
Dorman M630941 brake master cylinder for the 2014-2017 Dodge Journey turns pedal force into hydraulic pressure for the brakes. This Dorman brake master cylinder is made entirely of new materials.
A soft or sinking brake pedal, brake fluid around the cylinder body or a brake warning light can be signs the master cylinder is worn. Before replacing it, look over the cylinder and the lines near it for fluid leaks with the engine off and cool, because a leak elsewhere in the brake system can also leave the pedal soft.
This master cylinder fits the 2014-2017 Dodge Journey, which takes one. The listing is one master cylinder.
