• Hearing an abnormal sound: Hearing weird or abnormal sounds coming from the wheels when applying the brakes may be a potential problem.

• Vibrations from the brakes: Unreasonable worn rotors vibrate infrequently and cause vibrations felt in the pedal.

• Break Fluid Leaks: Leaks from the caliper might be accommodation to the pressure sealing range of the brakes. It might not just make a mess of leakage, but also take away from its ability to stop the vehicle.
