turning in rear caliper piston

["Linus D. Toy" <linust@interramp.com>]

gonna start my brake project (pads & rotors, x 4 corners) this evening...

the rear calipers on the '91 200q is a bit different from the earlier cars.
in addition to being larger (43mm diameter), it doesn't have the large
hex-head socket into which I would put an allen-key wrench.  instead, there
are two notches near the perimeter of the piston.  

other than the careful use of a vise-grip or channel-lock pliers (someone
really suggested this), has anyone another idea on getting these turned back
in?  i'd hate to take this to a dealer over this small issue, but...

thanks,
linus
