<p>A vehicle brake of the caliper type having electrically actuated active adjustment of the running clearance of a brake lining (26) relative to a brake rotor (12), wherein, for brake operation, angular displacement of a rotatable component (14) of the brake by an external actuator causes axial displacement of a tappet arrangement (22,24) within the brake whereby to transmit the actuator input load to the brake lining (26) of the brake. The brake includes a switch for supplying a brake de-adjust signal when the brakes are to be opened for example for lining replacement. The switch is mounted on or in the body of the brake caliper and provides a non-contact switch arrangement actuated by a rotary movement provided by the rotatable component (14) of the brake in response to lining wear.</p> |
