'97 Corolla Dude

I'm changing the pads on my 97 corolla conquest. This is for the rear wheels: I have removed 3 bolts, 2 that hold the caliper braket and one at the bottom of the caliper. Still the caplier isnt coming off. There doesnt seem to be any other bolts that i can remove. There is nothing at the top of the caliper. there seems to be a round thing where a bolt would normally sit but there is no way to remove it. However the front calipers have bolts holding the top and the bottom in. What bolt am I missing for the rears? This is the bottom of the caliper.. no problems here.. http://img269.imageshack.us/i/picture004kt.jpg/ With this picture, the round thing in the centre is at the top of the caliper where i think should be a bolt. This is what i cannot remove. In the middle of the round thing is a rubber peice. The bolt on the right is holding the bracket and that has been removed. http://img269.imageshack.us/i/picture005yd.jpg/

Hey, Ive got a 97 Corolla and the remote battery is dying. I bought a new one because I was told by Toyota that you cannot open the remotes to change the battery. I dont have the owners manual and im not sure how I program the new remote into the immobiliser. In the glove box is the security box where you put the remote in, but it doesnt seem to be working. I might have to push a few buttons but not sure which ones. Can anyone help me out? Cheers
