Disc brakes on bicycles work on a similar principle to motor-driven vehicles. By operating the brake lever, either hydraulic pressure or the mechanical pull transfers the force from the brake lever to the brake pads and ultimately to the brake disc. The friction between brake pads and brake discs ultimately leads to a reduction in speed. In contrast to the classic rim brake, disc brakes offer several advantages. The braking effect of disc brakes is less affected by wet conditions. The rim is also protected and rim damage does not affect the braking effect in contrast to the rim brake. In the case of a hydraulic disc brake, a minimal change in pressure on the brake lever is sufficient to initiate the braking process, which leads to a more precise dosage.
