Wear detection probe for a brake pad
First Claim
1. A wear detection probe for a braking element, having a holder with front and rear ends, a detection wire arranged in a path in the holder such that the detection wire has a fold in proximity to the front end of the holder, ends of the detection wire extending to the rear end of the holder, the probe detecting when the braking element has worn to its operating limit by detecting when the fold of the detection wire has been cut by a rotor, comprising:
- at least two arrangement grooves formed in an outer surface of the holder to define a portion of the path and to extend substantially from the rear end of the holder to the fold, the detection wire being fitted in the arrangement grooves, the restricting means comprising a rib projecting at the rear end of the holder in a position to partition two extending portions of the detecting wire extending respectively from the arrangement groove, and a restricting means for preventing the detection wire from coming out of the arrangement grooves.

Abstract
A wear detection probe for a braking element includes a holder with opposed front and rear ends. A portion of the holder near the front end is configured to retain a detection wire. Thus, after sufficient wear of the brake and the holder, the detection wire will be broken to produce a signal indicative of brake wear. The holder includes two arrangement grooves extending from the abradeable portion of the detection wire to the rear end of the holder. The wear detection probe further includes a rib. The extreme rear end of the rib may include a slot, and a heat shrinkable tube may surround the wires and engage partly in the slot.
