I noticed a noise problem with my brake. How can I solve it?

The first thing to be remarked, is if we hear the noise during the braking or during the riding but without the brake application.

• We hear the noise during the braking. There could be four different causes:

1. possible contamination of rotor and pads from external materials, such us oils used to lubrificate the parts. Please clean the disc and substitute the pads.
2. excessive use of pads, and this can also damage the rotor. The only solution is to substitute rotor and pads.
3. if caliper and adapter are incorrectly tighten. Please try to correctly tighten them both.
4. resonance between brake and frame. We can only suggest to change the pads compound to reduce or eliminate the noise.

• We perceive the noise continously, not only during the brake application. There could be foour causes:

1. the caliper is uncorrectly centered on the rotor. Please try to center it by untighten a little bit the caliper’s screws so that the caliper can move a little. Keep the lever stopped and tight again the caliper’s screws.
2. the pads’s spring can be broken or become slack. Please substitute them.
3. the rotor can be deformed or not straight (because of an accident, or a wrong assembly). Substitute the rotor.
4. wrong alignment of the rotor inside the caliper, caused by different components of the bike not related to the brake system. Need to eliminate/substitute the wrong component.
