Dorman - First Stop Brake Master Cylinder P/N:M133745
Dorman M630317 brake master cylinder for the 2002-2007 Mitsubishi Lancer turns pedal force into hydraulic pressure for the brakes.
A soft or sinking brake pedal, brake fluid around the cylinder or a brake warning light can mean the master cylinder is wearing out. Before you replace it, rule out a leaking line, hose or caliper and a low fluid level, since those can soften the pedal too.
This master cylinder fits the 2002-2007 Mitsubishi Lancer, and the car takes one.
