Brake makes noise / squeak
My brakes squeal or cause a (regular) grinding noise.
- Make sure that your brake pads still have enough lining or have not worn out.
- Check the position of the corresponding brake calliper and recenter it if necessary.
- Therefore, slightly open the two adjustment screws on the brake caliper adapter so that it can move freely (Allen key size 5)
- Pull the brake so that the caliper centers itself and carefully retighten both screws. Make sure that there is a small, even gap between the brake pads and the brake disc in the unbraked condition. Brake pads and disc have to be parallel!
- Inspect the brake disc for unevenness or whether it is bent in places.
- Grade the brake disc with an appropriate tool or replace it if necessary.
- Also, make sure that there are no external objects on the brake discs / pads. Even moisture / water from e.g. rain can cause squeaking noises which disappear as soon as the brake system is dry again.
- Also, make sure that the brake pads are not glazed. Remove them and check the surface for reflections / shimmering. The pads are normally matt.
- In the case of glazing, simply remove the top layer of the coverings evenly with fine sandpaper / file.
