ABSTRACT:
A disc brake assembly wear indicator configured to be examined by physical contact, i.e. touch, as well as by eyesight to determine wear of the brake assembly friction couple. Physical markings are provided on the assembly carrier and caliper in locations selected so that the tactile-sensible markings are furthest away when the friction couple is new or unknown and adjacent each other when the friction couple wear is at the minimally acceptable level.
