Hard to see. I need to get the wheel off really. I put new discs n pads on it a few years back and just cut the wire off the pad as there was nowhere for it to go. Remember the chap who id bought the car telling me the wiring was disconnected. So i assume the wiring has been bridged and tucked out of the way? Is the wiring a loupe system or just a single wire that earth's on the disc when the pad wears out?
