- Fits: the 1991-1994 Nissan Sentra and other vehicles

A brake pedal that sinks or feels soft, fluid around the master cylinder or a brake warning light can mean this part is wearing out. Before you replace it, rule out a leaking brake line, caliper or wheel cylinder, because a leak elsewhere in the system can show up the same way. A shop can pressure-test the hydraulic system.
