A brake master cylinder may need replacing if you notice a soft or sinking brake pedal, brake fluid leaking at the master cylinder, or a lit brake warning light. Other brake faults can cause these signs too, so diagnose the system before replacing parts. Consult the vehicle service information for the correct fasteners, torque values and bleeding procedure.
