A master cylinder may need replacing if you notice fluid leaking at the unit, a brake pedal that feels spongy or slowly sinks under steady pressure, or a fluid level that keeps dropping. Diagnose the cause first. After installation, bleed the brake system as the service procedure directs. See the Buyer's Guide tab for every listed application.
