Dorman - First Stop Brake Master Cylinder P/N:M630615
Dorman M630647 brake master cylinder for the 2008-2009 Dodge Caliber turns pedal force into hydraulic pressure for the brakes. The two outlets on this Dorman brake master cylinder send that pressure on to the brake lines.
A soft or sinking brake pedal or a brake warning light can mean the master cylinder is worn, though a leaking brake hose or a worn caliper can be behind those signs too. Find the cause before you replace it.
This is a direct-fit replacement for the 2008-2009 Dodge Caliber, which takes one master cylinder. The listing is a single piece.
