What is the problem when the rear brake of a motorcycle does not rebound?

Motorcycle rear brake does not rebound due to: rust on the brake rocker arm shaft or brake cable, excessive wear of the brake shoe block, damage to the brake cable wire, deformation or jamming of the brake pedal or handle, or excessive dirt or deformation in the brake lower pump. Braking, also known as stopping, refers to the action of stopping or reducing the speed of running locomotives, vehicles, other means of transport, or machinery. Motorcycles are driven by gasoline engines and are two- or three-wheeled vehicles that rely on handlebars to steer the front wheels. They are lightweight, flexible, and fast, widely used for patrol, passenger and cargo transportation, and also serve as sports equipment. Broadly speaking, motorcycles are divided into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes.
The other day when I checked my friend's motorcycle, I found that the rear brake pedal wouldn't return after being pressed. This is usually caused by internal sticking in the brake system. Focus on checking whether the brake pump piston is stuck by sludge, especially after riding in dusty areas. Also, check if the return spring is deformed or broken, as old bikes often suffer from spring fatigue. Brake fluid that hasn't been changed for too long can also become viscous, making piston movement difficult. If the brake lever length has been modified, mismatched design might affect the return. If you notice this issue, don't force riding, as continuous friction on the brake disc can cause overheating and deformation. Take it to a professional shop to disassemble and clean the piston, then replace with new brake fluid to solve the problem. Regular maintenance of the brake system can prevent such issues.
