What is the best way to remove the front brake caliper pistons from the calipers??? Thanks.

About halfway down on PMB's tutorial page.

Small block of wood with folded rag over it to catch piston, then compressed air in bleeder.
Keep every thing covered so NO brake fluid flies out.

I had one stuck badly. Try a C-clamp to push it in first. I reconnected it to the brake line and clamp the other piston. Insert a rag to cushion the piston pop. Use the pedal pressure to free it.

Thanks for all the replies. Compressed air, PB blaster and a block of wood did the trick.
