Recently purchased some Hawk HPS brake pads from American Muscle. The front pads went on in about 30 mins, no problem whatsoever and I'm a newbie as far as wrenching goes. However, the back is a different story. Basically, I can't get the caliper to go back on. It appears that the Hawk pads are too thick! There are 2 bolts holding the caliper on, interestingly the "socket" that excepts the bottom caliper bolt adjusts/moves in and out. Is the top one supposed to do that too? Because that is the only thing keeping me from bolting the caliper back up, I can't get the top of it seated properly. When I put the stock pads back on, everything is fine b/c I have more room to work with since they are worn down. The bottom is easy b/c the "socket" that accepts the caliper bolt just moves in giving me more room. I am hoping that one of you will tell me that top "socket" is supposed to move/adjust as well b/c then I'll just know it is seized up or something and I gotta bang on it. I wasn't sure if it was supposed to move like the bottom so I didn't wack on it too hard. Let me know what you guys think or if you've had similar problems.
