A pedal that feels spongy or sinks, or brake fluid showing around the master cylinder, can point to a failing unit. A leaking brake line, a worn caliper or air in the system can also be behind those signs, so find the cause before buying. If a failed master cylinder is the cause, this one replaces it.
