I spoke with my mechanic yesterday and he said that you can renew the outer seal without removing the pistons from the calipers. These seals come with the repair kit. I'm not sure if any other seals (inner seals?) come with the kit, but the outer ring seal can be replaced easily. He also mentioned that rebuilding the caliper is not that hard if you are careful and methodical. I've ordered the seal repair kits...we'll see how it goes. I'd like to renew the seal without having to rebuild the caliper.
