Screw the piston puck in clockwise. There is a tool for this (KN or KY) that is a box with little dowel pins to fit the slots in the caliper piston. What you are actually doing is resetting the parking brake. As the pads wear and you set the parking brake, each actuation of the parking brake foot lever ratchets the piston outward to componsate for pad wear.
there is a special tool that can be purchased at any auto parts store made specifically for compressing brake caliper pistons. I personally use a 4 inch c-clamp. works every time.

with a c clamp. put a block of wood or your old pad over the piston and tighten with clamp.

with a tool that looks like a cube and you attach to a ratchet
Take a compression test Could be a bad head gasket Bad plugs? Bad wires?
You don't remove the piston, you just compress it. Loosen the cap on the master cylinder and then compress the piston all the way in. You can then remove the old pad and install a new one.
Buy the Hayes Repair manual and it details the procedure
caliper piston does not retract with moderate C-clamp pressure - not willing to force it
Pontiac Grand Am was created in 1973.
Make sure the cap is off of the brake master cylinder. You can use a tool designed to move the caliper or a c-clamp. If the piston is too far out it may not go back into the caliper.
Bad plug? Bad wire? Bad piston or valve (do a compression test)
