Why does my new bike squeak when I brake?

“Squealing brakes can occur for several reasons, usually, if you have some grease or oil on the brake pad, rotor or wheel rim or the contact between the braking surfaces is misaligned.

Is it normal for brakes to squeak after changing them?

The leading cause of brakes squealing after replacing the pads is excessive brake dust trapped between the caliper and the rotor. … If this is not completed, the extra brake dust will be trapped between the fresh pad and the rotor. When heated, it can create an annoying squeaking noise.
