Abstract
A wear adjuster, securable to disc brake caliper structure includes, a stem extending along an axis about which the stem is rotatable in opposite directions, a spindle driver securable to an axial end of the stem to transmit rotational motion of the stem to an adjusting spindle, and an input element receiving input force supplied to the wear adjuster to produce rotation of the stem. A running clearance element is rotatable together with the input element to a limited extent, and a ratchet arrangement, located between the input element and the running clearance element, initiates any necessary adjustment for wear after rotation of the input element beyond the limited extent, and completes such adjustment during return rotation of the input element. To avoid transmitting an excessive amount of the input force received by the input element, a lost motion connection is defined between the ratchet arrangement and the input element.
