i think that on the older indys like this you do have to take the chain case out. i replaced my secondary cluch shaft on my 90 indy 500 couple of months ago and did the brake pads as well. as far as i remember, the only way to get the caliper out is to pull the chain case first. there are 4 bolts holding the caliper to the chaincase, and that is set around the brake disk. the disk is held in place on the shaft by 2 snap rings (its keyed on the shaft also), so if the chaincase is still bolted into the sled, there is nowhere for the brake caliper to move even after its unbolted. i personally found the easiest way to take the chain case out was to pull the whole rear skid out and the track. when i did it, the track was still putting weight on the drive shaft, so it put pressure on the lower bearing in the chiancase, made it almost impossible for me to get the chaincase out. so i just took out everything, only like an extra 20min to pull the track. i would recomend that you change all 4 bearings while you have your sled apart. it is a pretty big pain to tear everything down to get to the brakes, so replaceing $60 worth of bearings at the same time might be worth it. also, you could to here...
