Having only 14,000 miles on bike, I did not rebuild the front. Parts looked ok. Just cleaned it all.
Winter is not over, might go back in and put new seals and wipers in.
Just did the back brake. New seal kit and new pads. For $30.00 I should have put new seals in front.
I still went with the permatex coating on the pistons on back.
I think you did a good job Straightleg. But I agree with some of the others about using caliper grease on the inside of the pistons. I too have rebuilt a lot of calipers over the years and always used brake fluid for lube. Never had a problem. I'd be interested to see over a period of time, if the caliper lube inside the piston bores causes any problem. Keep us posted.
