A mechanical anti-lock braking apparatus for intermittently releasing pressure applied by a brake shoe to a wheel being braked includes a control member, a power input for causing the control member to rotate with the wheel around a rotational axis, and a control input for changing the position of the control member relative to a follower connected to the calipers or brackets to which the brake shoe is mounted. The control member and/or the follower has a shape which causes the follower to oscillate as the control member rotates, with the relative position of the control member and follower determining the magnitude of the oscillations.
