Question for those that have rebuilt stock calipers
I've got the rebuild kits for the front and rear calipers. I'm looking at the FSM and it states to replace the bearing on the rear calipers, but i don't see a replacement in the kit. Am i missing the bearing? Or does the kit not include it?

i don't think rebuilding the rear calipers is something too many have done. i did the fronts, it was all just rubber seals. any particular reason you're rebuilding the rears?

I rebuilt the rears and also had no such bearings. I bet they are for the slider rods and mine still operated smoothly. I would'nt worry about them if your sliders are still moving freely.

The bearing is for the e-brake mechanism on the caliper. I 'm sure you could get a replacment from Ray, but I'd inspect the exsisting one for smooth operation and play. If it looks good just clean it well and lightly gease with high temp grease.

At the track I once cooked the grease on the rear sliders so bad that the calipers bound up. Just removing the slider pins was quite a task; I thought they were going to strip the caliper holes! I couldn't believe it. After getting the pins out judicious use of carb cleaner removed all the glazed grease from the slider pins and their bores in the caliper. I then used high temp brake grease from NAPA to lube the pins up and have had no more problems. With the rear rotors removed the calipers should freely slide nice and smoothly back and forth. If they don't, clean the old grease out.

on another note, the shops in my area suck. the SIXTH shop i went to finally said they could pop the pistons out of the front calipers.

well the honing question is moot now. One of the pistons got too damaged when the shop had to pull it out because it was frozen. looks like i'm going to get some rebuilt calipers from NAPA instead
