Has anybody replace their rear disc brakes? I am trying to do this and what I tought was the screw that will take out the caliper was not. I have done a lot of brake jobs but this one stumped me. Anybody have a link I can go to to see the diagram or maybe tell me which bolt to take out. I see 4 bolts. 2 small ones by the caliper (which I tried to take out but it just keep turning and turning without coming out and 2 big bolts that looks like that holds the assembly.

I tried going to google but can't find any pictures of the rear brakes assembly.

Thanks in advance for any help.
