Abstract
A system for monitoring engagement and wear in a brake include: a pin, a first marker positioned on the pin at a first location; a second marker spaced from the first marker long the pin; and a first fixed sensing arrangement. The pin extends in an axial direction parallel to the axis of rotation, and is in contact with and moves with the moveable brake pad in use. The first fixed sensing arrangement is adapted to provide a first signal when adjacent the first or second marker, and a second signal otherwise. The first and second markers and the first fixed sensing arrangement are positioned such that the second signal indicates that the brake is in the engaged position, and a change from the second signal to the first signal indicates that the moveable brake pad and the second brake pad have been worn down by a predetermined amount.
