FAQ
What to do against squealing disk brakes?
Squealing sounds occur because of swings and vibrations. Due to the multitude of the involved components, the cause is often not visible at first glance. Check the following points:
- Is the brake calliper trued correctly?
- Does the disc rotor run even, does it happen to have a bash? If this is the case, remove it by carefully straightening the disc rotor.
- Are the brake pads okay? Glazed pads might be the cause for squealing sounds. Here, the roughening of the surface with fine-grained sandpaper might help.
- The disc rotor should be free from contamination.- All the fixing bolts as well as the quick release skewer should be tightened.- The spokes' tension should be constantly high, loosened spokes cause vibrations.
- The exchange from sintered metal pads to organic pads minimizes the noise emission considerably. Most of the disc brake manufacturers offer these kind of pads as accessories.
- Grommets for the fixing bolts, which join the adapter to the fork/rear body, may also minimize squealing sounds.
