I'm sure you're glad that you now know you didn't cause the problem to the pads or rotors, fourfourto!
I haven't heard back from the dealer all day .. they're closed now. He told me on Saturday that he'd call me today. I'll call him in the morning for an update. I'm thinking that they found the problem. Eight days today without my H3 ... BUMMER! We live on a hill, so I wonder if all of the ups and downs brought this problem out (just normal street driving). But, hey .. it's a Hummer!
