What is the reason for the motorcycle's rear wheel locking up and not rotating?

[LaAlexa]

Motorcycle rear wheel locking up and not rotating is caused by the brake not releasing. The solution is to remove the exhaust valve, then use pliers to slowly extract the piston, sand it finely, polish off the rust, reinstall it, and bleed the brake. When separating the caliper, be careful not to lose the small oil seal. Motorcycles are gasoline-engine-driven vehicles with handlebar-controlled front-wheel steering, available in two or three wheels. They are lightweight, flexible, fast, and widely used for patrol, passenger and cargo transport, as well as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes.
