i can't. it's too hard. they only need turned a little (one by about 5 deg., 
the other maybe 20 deg.), but i can't find anything that will do it. last 
time i tried i screwdrivered my finger. i thought i recalled keith saying a 
year or so back that he had a tool designed to rotate the piston, so i asked 
a vw mechanic of 35 years i know if he had had such a thing and he hadn't 
heard of it.

thus the surface area of the pad is greater :-)
