I fully  expect the bores to be totally corroded, so of course I'll 
have to split  the calipers to clean them up. The manual says don't do 
it, but I don  think I'll have a choice


"DO NOT PART THE TWO HALVES OF THE CALIPER"
Yeah you can split them but it's best to do it at night in a closed locked  
garage so the caliper police don't catch you doing it... It's kinda like  
removing mattress tags... under penalty of law...:-)
 
Actually it's hard to clean the bore WITHOUT splitting them, especially the  
top side of the groove where you can't see. There's usually a corrosion build 
up  in there, I use a little bent scraper to clean it out. It can get to the 
point  of effectively making the groove narrower & the seal wont fit  properly. 
Pegasus sells the square-section o-ring as well.
The difference in the pistons is the style of dust seal... & price. I  don't 
use the dust seals so that's a moot point.
There's no torque spec, I use 40ish on the 3/8 & 60-65 on the 7/16  bolts.
Like Steve said, there are different pads to suit big & small pins,  & the 
pads differ in profile of friction material as well, tapered &  straight-sided. 
I like the tapered because the straight sided pads will usually  wear uneven 
from top to bottom,  more towards the OD of the disc, where the  speed is 
greater.
