Calipers are shipped from the factory with the piston fully depressed. If yours was not, either someone did not do that or someone else bought and returned it that way.
Providing that the piston has not popped out of its bore, you should be able to retract it using a large "C" clamp. It's best to place an old brake pad on the piston to protect it from damage while doing that. If you have it connected to the rubber brake line and it will not retract, open the bleeder valve on the caliper. If it then retracts, likely the rubber hose has an internal problem and needs to be replaced.
If your original problem before you replaced the caliper was premature wear on that brake, I'd suspect that hose is at fault.
Always bleed the system after replacing any caliper, line, or other hydraulic component.

Have you tried opening the bleeder screw? Is it on the car?
It's unlikely that the caliper is bad if it is new. So, it might be a restriction in the hydraulic line leading to the new caliper.

How to put rear brakes on


Remove the caliper mounting bolts and remove the caliper. Replace brake pads as necessary. Special tool is required to retract caliper piston to fit over new pads. (see picture below)
Retract piston in caliper using special tool to rotate clockwise and make sure the notch in the piston is aligned properly so the tab on the inner pad will fit in properly.
Reinstall caliper assembly and caliper mounting bolts.

How can I change the rotors and brakes on a 2006 Cadillac?


Front brake
Step 1: Identify Front Disc Brake Components
brake_pads_rotor.jpg
Front Wheel Drive Brake Assembly
Most front disc brake components include: brake rotor, brake pads, brake caliper, caliper mount and brake flex hose. Brake service usual occurs between 20,000 and 40,000 miles depending on driver habits, road conditions and brake pad/ rotor materials used.
Step 2: Remove Brake Caliper to Replace Pads
brake_pad_set.jpg
Removing Brake Caliper Mounting Bolts
Locate primary caliper mounting bolts; apply wrench pressure counter-clockwise (When looking at the head of the bolt) to remove the bolts, upper and lower. Make sure the bolt threads are in good shape and replace if necessary.
Step 3: Remove Front Brake Caliper
remove_brake_caliper.jpg
Remove Front Brake Caliper
After removing the primary caliper mounting bolts lift the brake caliper off of the rotor and then tie or secure to the side, being careful not to bend or kink the brake caliper flex hose. Thoroughly inspect brake caliper and brake hoses for leakage, cracks or chaffing and replace as needed. Next remove the brake pads (If not mounted in the caliper) and secondary caliper mounting bolts. Notice how great protective gloves work, most technicians use them on the job today.
Step 4: Remove Brake Pads
remove_brake_pads.jpg
Remove Front Brake Pads
Once the brake pads have been removed, make sure if there is anti rattle hardware to transfer to the new brake pads. Some brake pad manufacturers will include the proper lube (Caliper slides) and anti-rattle hardware to ensure proper performance of their product.
Step 5: Remove Caliper Mount
remove_brake_pads_holder.jpg
Remove Caliper Mount Bracket
Finish removing secondary caliper mount bolts and remove caliper mount. Note: clean and lube caliper slides and pad friction surfaces of all foreign material or build-up.
Step 6: Remove Brake Rotor
brake_rotor.jpg
Remove Brake Rotor
With the caliper mount out of the way you can now remove the brake rotor. Sometimes it can get stuck so you may need to tap it with a hammer or use penetrating oil to free it up. Some manufacturers use small screws to hold the rotor on as well. Clean and inspect wheel studs, replace if any are damaged. Also clean bearing hub rotor mount surface to ensure the proper mounting of the new brake rotor. Inspect the ABS sensor wheel for cracks or damage and replace as needed.
Step 7: Depressing the Brake Caliper
compress_caliper.jpg
Resetting Brake Caliper
To install the new brake pads you must retract the brake caliper piston. Remove the master cylinder lid or open the brake caliper bleeder screw to allow excess brake fluid to be released if necessary. Install C clamp tool and gently tighten clamp until caliper piston is fully depressed. Note: use old brake pad to protect the caliper piston. Close the bleeders once the piston is retracted completely
Step 8: Installing New Brake Rotor
new_brake_rotor.jpg
Install Brake Rotor
Install new brake rotor, the new rotor is manufactured with a protective film over the rotor to keep it from rusting, remove protective film with brake cleaner before installing; also after the brake job is complete you may experience a small amount of smoke from the rotor when first used. This is normal and will go away after the first couple of uses.
Step 9: Installing New Front Brake Pads
new_brake_pads.jpg
Installing New Brake Pads
Reinstall the front brake caliper mount, and then install front brake pads. Make sure the pads are seated properly in the caliper mount; it must be a close fit to work properly..
Step 10: Reinstall Front Brake Caliper
front_brake_rotor_pads.jpg
Re-Install front Bake Caliper
Reinstall front brake caliper and reinstall caliper-mounting bolts, recheck all mounts and mounting bolts. Check the caliper slides to be sure there is no bind and that the caliper moves freely back and forth on the caliper slides. Bleed brake system per manufacturer's specifications to relieve any air trapped in the system. Before driving the vehicle, push the brake pedal down and let it up slowly, repeat until normal brake pedal operation resumes, this operation is forcing the brake pads to travel to the brake rotors.

Put new brake pads on, now brakes were smoking. Sticking caliper?


They are rather easy to replace, disconnect the brake hose, and remove the caliper as you did replacing the pads. You'll need to then bleed the caliper until clear fluid, with no air bubbles come from the bleeder screw. Check that you don't have a collapsed brake hose, not letting the fluid return to the master cylinder.

Just put new brake caliper on front driver side


Gravity bleed caliper, just open valve and have a coffee break and close it. Did you buy a loaded caliper with new pads on it? Check the rear wheel cylinders they may be the cause of your mushy pedal. They are cheap too.

Compressing calipers to put on new brake pads on 1988 volvo 740


There is a tool available from most auto parts supply outlets, it is a plate that has a compression bolt through it, you slide the plate into the caliper, and tighten the bolt against the piston, then keep turning until the piston is all the way in. These are relatively inexpensive and good to have for next time.

hope this helps.
