Hi folks, I have a set of airheart 175s on the front of my bucket and they are squealing like crazy. It's embarassing to come to a stop now. I have tried everything I know,... scuffing the rotors, scuffing the pads, I even put a dab of rtv on the back of the pads. They still sound like nails on a chalkboard. I have the hard compound pucks in there because speedway was out of the soft ones. Is there anything I can do other than changing the pads, and will that stop the squeal?
