If the pistons have a cross in them .. Try a large screw driver and turn them while you push down
tired turning the piston

It sounds like you have air in your brake lines. It sounds like you have air in your brake lines.
I assume you mean the brake "calipers." There is a special tool available for this purpose, but you can either use a C clamp to compress the piston back into the caliper after you remove the pads, or you can insert a flat blade screwdriver between the pad and rotor and pry outward to force the piston back in. Apply a steady force and give the piston time to retract. You are forcing the brake fluid back up into the master cylinder, so it takes some time. Be careful not to damage the rotor or the piston seal while prying.
Having this problem with changing rear brake pads on new Beetle. Could not get piston to return to a position that would accomodate the new pads. VW dealer was fat lot of use - said I should loosen the cap on master cylinder reservoir. Have now discovered that there is a special tool - because the piston must be pushed in AND rotated at the same time. Saw pic of tool on dieselgeek.com/golf_iv_main.php - it cost $49, and seems to be usable on most VW and Audi calipers. There is a special nut with two spigots which engage in the slots on the piston surface allowing rotation to be enforced. Looks like you would rotate the piston first and then compress it to required position. Have not bought tool. The Dev
Usually it's low brake fluid or a problem with the abs. Check the brake fluid reservoir. Often the brake fluid will go down as the brake pads wear and the calipers has to travel further.
# Preparation For Brake Pad Replacement # Remove the Wheel # Unbolt the Caliper # Remove the Old Brake Pads # Compress the Brake Piston # Re-Install the Brake Caliper
Remove wheels Re-install 2 lug nuts to hold rotor in place Remove 2 caliper mounting bolts Slide caliper off rotor A special tool (not expensive) may be required to retract pistons in to caliper body available at Sears or auto parts These piston may be threaded to accomodate parking brake
worn pads, calipers sticking or disks warped, more than likely pads though
They either need to be adjusted or they were not properly reassembled. See the related article for adjusting and changing this brake.
i had a similar prob but it was related to the brake booster. it is a cylendrical device that creates brake pressure and when deffective causes the brakes to be engadged and causes brake wear and slow gas mileage and warpping of brake drums and excessive wear of brake pads..... often over-looked.
The rear brakes on a 2001 Monte Carlo are replaced by removing the rear wheels, unbolting the calipers, and taking out the old brake pads. The new pads can then be installed and the brakes reassembled.
