Dorman - First Stop Brake Master Cylinder P/N:M390296
Dorman M630025 brake master cylinder for the 2005-2010 Dodge Dakota and other vehicles turns pedal force into hydraulic pressure for the brakes. It replaces a worn or leaking master cylinder in the brake system.
A soft pedal, fluid seeping around the cylinder or a brake warning light can mean the master cylinder is worn, though a leaking brake hose or a sticking caliper can be behind them too, so find the cause before you replace it.
This master cylinder is a direct-fit replacement for the 2005-2010 Dodge Dakota and the 2006-2009 Mitsubishi Raider, and each takes one.
