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.
