Caliper ReBuild
The shop manual has a step by step on the repair as well as the "Genuine" tool cache required... I rebuilt a caliper for a '90 RRC without much trouble using a pair of channel locks and a "C" clamp. I found that it was a chore.
My '96 D1 required a rebuild and I opted to purchase RN's ProLine caliper. I understand that it is twice the money than the rebuild kit, but I completed the job in under 30 min. from soup to nuts and no headaches.
