A caster is provided that includes a wheel rotatable about a wheel axis of rotation, a housing, a locking arm linked to the housing, and a locking bar linked to the housing. The housing includes a housing side wall and a housing detent formed in the housing side wall. The locking arm is movable between an unlocked position to permit the wheel to rotate about its wheel axis of rotation and a locked position to prevent or substantially restrict rotation of the wheel about its wheel axis of rotation. The locking arm is linked to the wheel so that movement of the locking arm between the locked and unlocked positions moves the wheel. The locking arm includes a locking arm side wall and a flared portion formed in the locking arm side wall and extending outwardly toward the housing side wall, the flared portion is engaged with the housing detent when the locking arm is in the locked position and disengaged from the housing detent when the locking arm is in the unlocked position. The locking bar includes a brake facing toward the wheel and engaging the wheel when the locking arm is situated in the locked position to prevent or substantially restrict rotation of the wheel about its wheel axis of rotation. The brake is an indentation formed in the locking bar.
