Thanks, kiwinPA. I'll definitely do something similar the next time I have to remove caliper pistons!
I cleaned up the calipers. The worst part was that the original piston seals were dissolved and had adhered themselves to the groves in the caliper. They fell apart when attempting to remove, so it didnt' all pull out... leaving a mess to clean up. Degreaser and a tooth brush resulted in minimal cleanup of the remaining material. Dremel with a wire brush resulted in getting most of the residue out of the gasket grooves, but I had to be super careful not to scuff the cylinder wall and with the angels I couldn't get it all out. A metal dental pick proved to be the final step... the angle was perfect and I was able to dig out the gasket grooves. I put them back together last night with all new rubber parts and pistons. They look sweet! I just have to get the master cylinder rebuilt before I assemble the front brakes and check functionality. I feel certain they will operate though... I still can't believe how much force it took to push the old pistons out. One of them really did not want to budge! -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
