Question: How do I fix squeaky bike disc brakes?

What causes disc brakes to squeak?

If the brake pad friction surface wears down enough, you’ll eventually hear a squealing noise because the pads (or what’s left of them) and rotor are making metal-on-metal contact. Another cause of noise may be warped rotors, meaning the pads cannot evenly make contact with the rotor surface during braking.

How do you stop squeaky brake discs?

Why do my brakes squeal at low speeds?

As described in some owner’s manuals, the squealing noise is caused by high-frequency vibration of the brake pads against the rotating disc. Vibration is the unavoidable result of friction generated by the pads as the caliper clamps them against the rotating disc.
