ABSTRACT:
A braking member for rotatable mounting on a wheel axle of a hand-driven wheeled vehicle such as a shopping cart has a first part having an opening for mounting on a wheel axle, and a second part releasably secured to the first part and having a braking surface adapted to engage the ground when the braking member is in an operative position. When the braking member becomes worn, the entire member does not have to be removed from the wheel or caster, but instead the second part is released from the first part while the first part remains on the wheel. The second part can only be released using a special tool which is provided to store personnel.
