Hi
I guess a lot of folk may not have the wear sensors installed, however if you do then the wire originally was attached to one of the brake hoses via a rubber loop. When the hoses are replaced then this loop is often lost. I originally used loom tape to attach the wire to the hose, however this is not too effective after a few years of use, so decided to make a clip to attach to the brake hoses and accommodate the wire. The photo is of a prototype in PLA, the ones I will use are in black PETG.
