Yes, it should.   However, there are locking rings which (probably) prevent 
the pistons from coming all the way out of the bores.

The caliper overhaul procedure (for the front calipers) is on page 12-10-02 
of the factory shop manual.   Please tell me you have a factory shop manual?   
For the rear brakes it's absolutely critical as they are very strange, and the 
procedure to overhaul them is complicated.

For the front calipers (which is what I presume you're talking about), you 
remove the calipers, remove the pads, use a plastic pick to remove the retaining 
rings and rubber boots from the pistons, then put a thin wood block between 
the opposing pistons and use compressed air to force the pistons out of their 
respective bores.

If you've removed the boots and retaining rings and the pistons won't come 
out all the way, they are hung up in there, and then you will have to use 
finesse and/or brutality to force/pull them out.

Oh, and the shop manual and all the associated goodies are available from the 
POCA store (www.panteraclub.com), either in dead-trees or CD-ROM format.

Good luck!

Mike
