Why do electric bike brakes squeak?

Disc brake or the brake pad is dirty

When you ride through muddy roads or puddles, there may be dust or water stains stuck to the disc brake rotor or the brake pad of your e-bike, and when you brake the bike it will squeal.
In addition, when you maintain your e-bike chain, you may accidentally get the chain maintenance oil on the disc brake rotor, and oil stains are also the main culprit for brake squeaking.

The brake pads are thinned or damaged

When you ride for more than a certain amount of time, brake pads will get thinner or wear out completely. Generally, the brake pads will become thinner after more than one year of use, depending on what terrain you use and how you use the brakes. If you always ride in mountainous terrain or downhill, the brake pads will consume faster while it is slower when riding on flat ground. When it is completely worn out, the outer iron sheet or plastic of the brake pad will rub against the disc brake rotor of the electric bicycle, and therefore, it will squeak.

Improper installation of brake pads

When your brake pads are not installed properly, it can cause them to rub against other components.
