A soft or sinking brake pedal, brake fluid around the cylinder or a brake warning light can mean the master cylinder is worn, though a leak elsewhere in the brake system can look the same. Before you replace the master cylinder, rule out a leaking line, hose or caliper, because a new cylinder will not fix those.
