help. pads getting stuck Options

[ghostdog]

I hate to only post problems but I need some help on this. the front-right brake pad seem to be getting stuck. I took it apart and it looked like the bracket that the pad fits into was slipping around, thereby getting the pad caught at an angle. so I replaced all the brackets but the pad still doesn't slide freely. its like the pad is too wide to fit in the slot, I don't know how else to explain it. so naturally I figured I'll grind the pad down, and now it slides but still gets stuck after some use. I've taken the damn thing apart 4 or 5 times and its really starting to irritate me. I'm contemplating covering the car in gasoline and throwing a match under it.

so I guess my question is. anyone had this problem? what exactly is happening because I can't understand how the pad slides properly for 2 years and now its too wide to fit in the slot? seems like the only solution is to buy a new caliper ... help me retain (whats left of) my sanity please.

makes me feel a lot better that its happened to other ppl. damn, I should come here more often cause ya'll are awesome .. but anyways, the rotor and rim obviously get really hot. I'm guessing thats going to cause warping if I continue to drive like that right?

so is the piston seizing up causing this? if I'm replacing stuff I should buy the whole thing right? thanks
