Channellocks, that's a good idea. I've used G-clamps in the past but that seems a lot easier.
My last car had Wilwood 4-pot calipers with stainless steel pots, so they had no rubber seals - didn't need them. As these have rubber seals, I wasn't sure what the best way was of retracting the pistons without damaging them. I've heard if you push them back any-old-how, you could push them on an angle and cause problems.
Thanks
