I have all ready worn through my front and rear ???? pads. There are clips on the ears/end of the pad that are almost touching my rotors. I usually go through three sets of fronts for every set of years. I've done near a hundred brake jobs after nearly 30 years of racing and I have never seen rear pad wear like this. The brass clip doesn't appear to be a retaining or anti-rattle clip and appeared very close to the rotor when fresh.Ford is saying pads are back ordered through June which is not going to work. I did buy a set of fronts when I got the car but never bothered with rears.I contacted my race car builder to reach out to Brembo for pads. Any hands on knowledge would be appreciated. I usually run my pads just shy of the backing plate which these clips will prevent.
