Disc brakes on the bike work on a similar principle as motor-powered vehicles. By pressing the brake lever, the force is transmitted from the brake lever to the brake pads and ultimately to the brake disc either by hydraulic pressure or the mechanical cable. The friction between brake pads and brake discs ultimately leads to a reduction in speed. Unlike the classic rim brake, disc brakes offer some advantages. The braking effect is less strongly influenced by wet disc brakes. In addition, the rim is spared and rim damage does not affect the braking effect in contrast to the rim brake. In the case of a hydraulic disc brake, even minimal pressure change on the brake lever is sufficient to initiate the braking process, which leads to a more accurate metering.
