How to fix squeaky disc brakes. Hereâs how to fix squeaky disc brakes on a mountain bike. The two main causes of squeaky disc brakes are an inadequate break-in (or bed-in) procedure, and excess brake dragging. Incompatible pads and misaligned brake calipers can also contribute to brake squeal.

As the brake pad material wears away the wear indicator starts making contact with the rotor, which produces a squealing sound. When you hear the sound it's time to have your brake pads checked and most likely replaced.
