Mechanical disc brake

A mechanical disc brake is a braking system in which a metal disc is attached to the wheel and rotates with it, but in this case the braking force is transmitted through a steel cable instead of a hydraulic circuit. When the brake lever or brake is activated, the cable pulls the caliper, which presses the pads against the disc, generating friction that reduces speed until the rotation stops. It is a simpler, more economical, and easier-to-maintain system, although it usually offers less power, less progressive braking, and requires more adjustments over time than a hydraulic brake.
