Rear Wheel Replacement Kit
The rear wheel contains the internal gear teeth that interface with the brake locking pin. A locked condition usually results from mechanical deformation of these teeth or grit ingress that prevents the pin from clearing the gear valley. Replacing the entire wheel assembly ensures a clean interface for the braking pawl.

Brake Actuator Pedal Assembly
The brake pedal controls the lateral movement of the locking pins via a cable or slider. If the internal return spring within the pedal assembly fails or the housing is cracked, the pins may remain under tension in the 'locked' position even when the pedal is toggled to green.

Front Wheel Swivel Assembly
If the symptom refers to a 'locked' steering direction rather than rotation, the front swivel housing is the culprit. This occurs when the vertical axis bearing is fouled by debris or the swivel-lock latch has failed in the engaged position.
