Carl,
I replaced my OEM pistons with stainless last year. No problems with
fit or function. I got the pistons from TRF, they were about $20 each,
I could have got chromed steel for about $12. Thirty two bucks was
small enough price not to worry about corroding brake parts.
BTW, you don't have to separate the calipers to replace the pistons.
Whether you should separate them at all, well, I don't want to start
that again. But if you do separate them, the torque numbers I got
from TRF are 75 ft-lbs for the large bolts, 45 ft-lbs for the small ones.
