Typical brake symptoms owners report

  • Brake pedal intermittently freezes or fails to respond, sometimes on the highway and sometimes on city streets, with no dashboard warning lights and no error codes found by dealers.
  • Brakes become firm with little stopping power, then travel almost to the floor before the wheels lock up and the car stops abruptly and without warning.
  • Front brake calipers seize, accompanied by a burning smell and smoke from the front wheels, with rotors, calipers, and pads replaced more than once without resolving the issue.
  • Brakes take several seconds to release when reversing, with the brake light staying on the whole time.
  • A clunk or sliding sound occurs when applying the brakes, sometimes paired with rattling noises from under the driver-side floor board.
