After reading the threads on putting a bike back in service after a long layup and the timing belt How-To I thought I'd try to keep moving in that direction. I ordered the timing belts yesterday (Goodyear 40274 $40.00 for both instead of the nearly $140.00 from Honda ... Thanks Randakk's) but they won't be here for a few days, so I ended up draining the oil and replacing the oil filter. Got a liitle more cleaning done on the front of the motor too.
Then I thought I'd get the brakes sorted out. All 3 calipers are sticking, but there is relatively clean fluid in both mastercylinders. That is unusual for me since most of the bikes that I have delt with have been sitting for 20 years or so and are solid crystals by the time I get them.

I have become accustom to getting lucky with this bike, so I was a little disappointed when I pulled the rear caliper apart.
I think that is why it was sticking

. I was still optimistic that a good cleaning would straighten things right up. I'm a glass is 1/2 full kinda guy. Then I got the pistons out.
It is hard to see, but there are significan pits on the sealing surface about 0.220" down from the edge. I checked on new pistons, but they are going to run around $80.00 a piece.

So between those and new dust covers I would be around $200 into the rear caliper before pads and I an just way too cheap to do that. So I started measuring the piston and where the seal sets in the caliper bore. With the pistons fully seated the worst of the pits will sit about 1/2 way on the seal. Once the piston is pushed out a bit all of he pits should clear the seal and it SHOULD be good. The diameters are in accordance with the service manual so here we go...
I just reassembled all the parts as is. We'll see if it leaks for now. If it is leak tight I'll put the new pads on and call it good. If not ... it is off to find another caliper...
