Well I honed them and put a rebuild kit in and bled the brakes tonight. Hopefully it will hold - I didn't see and dripping at least:) The rebuilt caliper had epoxy almost completely clogging the inlet hole into the caliper bore. There was some epoxy in the hole that transfers fluid to the other piston.
I also had to replace my rebuilt distribution block with an old rusty one because the rear seat (removed for rebuilding) was leaking. I collapsed the seat trying to get it tight enough to seal. Vanco said they would take care of it so we'll see on that.
I also learned that Right Stuff has reproduced the distribution blocks and will soon be reproducing the 2 1/16" 4 piston calipers! That's especially good news because there are no more rebuilt cores available from anyone, anywhere.
I hope to get off work a little early tomorrow and take the car for it's first venture out of the neighborhood.
