Question about 2003 Pontiac Sunfire
Remove wheel, remove capaliers, remove pads, purchase anti seizing compound and high temp grease. Use a 6 inch c-clamp and a piece of wood push the frount of the capaliers flush so the pads will fit. Before pushing the mechanism back into the capalier remove some break fluid from the unit so it will not overflow, remember to replace the fluid when pads are installed.

first, break the lugnuts loose on the front wheels, but don't take them all the way off. Then raise the front of the vehicle with a jack, and support with with blocks or jack stands. Turn the wheels to one side so you can see better. Check your brake fluid level, and remove some from the reservoir if it's full. If you don't do this, it WILL overflow. Start with whichever side you turned it to, grab the caliper, and pull it towards you with a good strong, even pull. It should move slowly, and then stop when you feel it bottom. If it doesn't want to move, you can use a flat screwdriver and pry it towards you by inserting the head of the screwdriver between the brake pad and rotor on the side closest to you. You can also use a c-clamp to compress it if available. Look on the back side of the caliper. You should see two bolts that have round heads, and take an allen wrench. You will need to loosen these bolts, and remove them. be cautious, you don't want to break the rubber bellows that they go into, and you also don't want to get dirt on them. These bolts hold the caliper on, and also allow it to "float," in essence letting it move with the rotor. once these bolts are out, the entire caliper will lift off. Pull the brake pads out, and put the new ones on; coating the BACK of the pad with the anti-squeal grease before installing. Next, put it all back together just like you took it apart. Turn the steering wheel the other direction, and repeat on the other side. When you're finished, make sure the brake reservior is full, start the car, and push the brake pedal in. It will probably almost go to the floor, but this is normal; the calipers are just adjusting. press the pedal again, and they should feel normal. Have fun, and enjoy the savings from doing brakes yourself. This is a perfect starter job.

When you changed the pads did you notice if one side was worn more than the other? The most common cause of pulling when you apply the brakes is a seized caliper. It won't work and the other does all the braking. Your left caliper is likely seized and needs to be replaced. Hope this helps.
