Disc brake friction couple wear indicator
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.
1. In a brake assembly, the improvement comprising a wear indicator that is capable of being sensed tactilely, wherein the wear indicator includes at least one marking on a disc brake carrier and at least one corresponding marking on a disc brake caliper,
wherein the indicator is comprised of raised regions on the disc brake carrier and the disc brake caliper.
2. In a brake assembly, the improvement comprising a wear indicator that is capable of being sensed tactilely, wherein the wear indicator includes at least one marking on a disc brake carrier and at least one corresponding marking on a disc brake caliper,
wherein the wear indicator is comprised of recessed regions on the disc brake carrier and the disc brake caliper.
3. In a brake assembly, the improvement comprising a wear indicator that is capable of being sensed tactilely, wherein the wear indicator includes at least one marking on a disc brake carrier and at least one corresponding marking on a disc brake caliper,
wherein the wear indicator is also configured to be visually inspected in lieu of tactile inspection to determine wear of components of the brake assembly, and
wherein the wear indicator is chemically marked to provide visual inspection.
