This is a common sound on Zero motorcycles, for reasons which have never been decisively explained.

Related Confirming Symptoms
  • Usually occurs only when pressing on the brake lever or pedal. Rarely occurs at specific speeds when brakes are not pressed (the pad(s) are resting on the caliper).
  • Vibration felt through the brake lever or pedal when squealing.
Effects
  • Brake performance seems technically unaffected.
  • As the loudest sound from the vehicle, this can be unnerving for rider, passenger, or onlookers.
Potential Causes
This was more common on 2013-2014 models which had cheaper / lower spec Brake Systems.
This suggests a design issue between the disc and calipers that tends to produce resonance the way the pad is mounted.
