What are the reasons for the motorcycle's rear brake not working properly?

[VanAlexa]

Motorcycle rear disc brake failure may be caused by insufficient brake fluid or a damaged oil pump. Below are the relevant details: Introduction: Disc brakes consist of a brake disc connected to the wheel and a brake caliper at the edge of the disc. During braking, high-pressure brake fluid pushes the brake pads to clamp the disc, thereby generating the braking effect. Classification: Disc brakes are sometimes referred to as rotor brakes and are divided into two types: standard disc brakes and ventilated disc brakes. Ventilated disc brakes have numerous circular ventilation holes drilled into the disc surface. The main advantages of disc brakes include rapid braking at high speeds, superior heat dissipation compared to drum brakes, consistent braking performance, and ease of installing advanced electronic devices like ABS.
