The moog suspension bushing was a nice choice.

Hi Jeff, Thanks for your reply.
Well “I went to school” on the worst caliper. One of pistons was so stuck that I had to use the brake systems hydraulic pressure (and really slam on the brakes) to dislodge it.
After a mmajor clean up I managed to pop out the c-clips that held the old boots to the cylinder lips. I put the pistons in the lathe and used 600 grit (wet or dry sandpaper) to pollish the crap off the chrome.
Long story short, beyond refurbing the the pistons and cylinders, putting in and on new seals and boots with plenty of the synthetic grease supplied with the seal kit, I also realized that the slide sleeves that ride in the rubber bushings were immobile. Of course I replaced the bushings with new ones from the seal kit and filled them with syn grease, however I should have been informed enough to check this on every pad change.
I find nothing in the brake pad changing instructions (Haynes) that explains how the caliper must “float” free and also that the pads themselves must not bind in the caliper “frames”.
Maybe these are things you can address in your very informative web site.
Sincerely, Tom Pitt,,,,,

Hi Tom, I dont currently have this posted as of yet but if you cannot find it in a Chiltons or Haynes repair manual then I will walk you through it. Its not that difficult to complete and does not require any special tools either. If you have to have these calipers repaired ASAP then you can replace them with new and rebuild the old ones at your convenience. I hope this helps. Jeff

I was really hoping to find info on how to put new cylinder seals (and dust boots) into/on my (Subaru) front calipers.
Do you have this info posted somewhere on the web?
