I just spoke to a guy from HPS and told him that I just put on a set of Hawk HPS street pads. (This is not my first time putting on Hawks or other brake pads.) I followed the bed in prcedure on the box and they squeal like a stuck pig! It is so loud it is embarrasing. I have drive on these for a few days hoping it would go away. The guy at HPS told me to take 200 grit sandpaper, cause it sounded like they glazed over. He said if that did'nt work then we would go to "step 2." What do you think?

Yes, hes exactly right. Sand your rotor as well and re bed them in. We recommend 120g sand paper but 200g will to the job as well.

I usually sandpaper my used pads each time I swap them, to make sure the pad surface is fresh & proper for bed-in. My HPS do not squeal like other people report, but when I bed them, I keep going until I see smoke coming from the pads... only then I stop.

Squeaks usually come from vibrations, so I would suggest you also lube the backing plates (and top & bottom contact points) and all the shims with anti-squeal brake grease or anti-seize.

Well first i'd ask "what did you do?" Can you outline what you believe started it? Glazing is usually caused due to overheating the compound balance in the brake pad material, which changes it - causing it to "glaze." But normally with glazing you see a white doughnut frost looking symptom on the pads themselves, or at the very least a oil like shiney substance on the pad surface. When I had HP+'s I did this to them and my girlfriend could hear me coming 2 streets away like i was the garbage man or something To fix it I used a belt sander, vice grips, and welding gloves with some medium grit to get past the ruined material. Also as mentioned, I would advice against sanding the rotors yourself unless your damn sure you can do it evenly.
