A few years ago I bought some Clarkes shimano fit disc pads from
Wiggle, and yep you guessed it……One of the front pads fell off with a very short time, coming down a hill. I always carry a good used set as spares, so carried on, then some while later, maybe 6 months , one of the rears fell off. Now I never fit pads by the same supplier to both axles.. Wiggle didn’t want to know. Nuke proof have always been good, can’t remember what else I got in there.
Now then, interestingly, some backing plates have holes in them, where the pad material is pushed into, to act as a key, to help the bonding, but the failed ones had no such holes, and were just stuck on.
