Mechanical disc brakes are controlled by a Bowden cable. The further and more the brake lever is pulled, the greater the friction and the braking effect. Compared to the hydraulic brake system, the mechanical brake system has the disadvantage of being somewhat less controllable. However, mechanical brake discs can be repaired more quickly and easily in the event of a malfunction, as no special tools are required. They often work with a one-sided piston, i.e. the brake disc is pressed by the moving piston against the inner lining, which is firmly anchored in the brake calliper. Despite all this, it is important to maintain and check the brake regularly.
