I recently installed Hawk HP Plus front pads for daily use and autocrosses. Initally I used regular brake grease and found that the brakes began to squeal loudly when hot. So I removed the pads and thoroughly greased them with ceramic grease from autozone. Though they are not as loud, they still squeal when hot, especially after highway use. Is there any solution other than different pads? I have never had this issue with any other pads. THanks.
