View source for Brake Squeal

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.
