Dorman - First Stop Brake Master Cylinder P/N:M39403
Dorman M630429 brake master cylinder for the 2006-2010 Chrysler PT Cruiser turns pedal force into hydraulic pressure for the brakes. This Dorman brake master cylinder is sold as a single piece and has two outlets.
A brake pedal that sinks or feels soft, or fluid around the cylinder body, can mean the master cylinder is worn. With the engine off, look the cylinder over for wet fluid. Fluid can also seep from a line or caliper, so find the source before replacing the cylinder, and have a shop inspect any pedal change promptly.
This brake master cylinder is a direct-fit replacement for the 2006-2010 Chrysler PT Cruiser, which takes one.
