Rear caliper question - Need quick answer!

[Per Lindgren]

Quattrophiles,

A few days ago, somebody posted the procedure on how to disassemble the
rear caliper to free up the handbrake actuator. I did that today, and
cleaned up a lot of rust and old goo. Now comes the big question.

How the hell do I compress the spring inside the caliper to get the
circlip back on? The spring is almost as hard as a valve spring, and
there's no way I can compress it with the circlip pliers. This wasnt
mentioned in the short writeup either...

I could use the answer pretty quickly as I'd like to try to get at least
one caliper finished tonight (it's 9:30 pm right now)
