with a tool that looks like a cube and you attach to a ratchet
with a c clamp. put a block of wood or your old pad over the piston and tighten with clamp.
caliper piston does not retract with moderate C-clamp pressure - not willing to force it
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.

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.

Whoever replaced your pads may have neglected to apply anti squeal goop to the back of the new brake pads. Brake pads should have some greasy stuff smeared on their surfaces where they meet the caliper, the caliper piston, and at the ends where they fit into the caliper. The squeal is caused by high frequency vibration where the back of the pad presses against the caliper and caliper piston(s).
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.
Use a screwdriver between caliper and front of piston to squeeze piston back, remove caliper via two bolts on rear inside of caliper. Slide caliper away from rotor and support to ensure you don't damage the hyd. hose. Remove pads from caliper, fit new ones same way. re-fit caliper.
Remove wheel, remove the two bolts in the calipers, pull up calipers, remove pads compress caliper piston with a c-clamp, be sure to have the brake fluid cap off the reservoir under the hood. - replace pads and reverse the order.
Caliper front? Use a "C" Clamp Caliper rear? Threaded Need a special tool available at Sears or auto parts (Not expensive)
