Know this has been discussed before but posts I'm finding are pretty old. Infrequently getting some really horrible noises coming from my front brakes. Sounds so bad I truly expect to see brake parts littering the road behind me! Started after I replaced the pads and turned the rotors about 6 months ago. Infrequently it will happen on level ground but there's a steep downhill grade I occasionally use and it does it almost every time when I start braking hard enough in order to make a left turn near the bottom of the hill. I've taken them back off twice now and reinspected them but I really don't see anything wrong with them or the installation. Suggestions appreciated.
