Why Do Bike Disc Brakes Squeal?

The most common reason disc brakes screech and create noise is due to brake pad contamination. This is frequently caused by an excessive amount of spray during chain movement. It is also important to prevent oil from becoming trapped between the disc brake and braking pads, since this will prevent the brakes from functioning correctly and causing the noise.

When it comes to brake squeal, the most typical problem is contamination or glazing of the brake pads or rotor. In the presence of contaminants (for example, oil from our fingers when we mistakenly contact the brake pads or rotor), the brake pads might lose grip on the rotor, resulting in vibrations and screeching as a result.
