Hi. Please see procedure below:
Remove the old Brake Pads
1 Park your car on a level surface. If you have a stick shift car make sure the car is in gear. Place blocks in front of the front tires so the car does not move while you are working on it.
2 Open the hood of your car and locate the master cylinder. If necessary, remove brake fluid until the level in the container is less than half full. A turkey baster is a good tool for this. Put the brake fluid in the plastic container and dispose of it the way you dispose of motor oil.
3 Raise the rear end of your car with your car jack. Remove the rear tire or wheel assembly.
4 Remove the parking brake cable from the back of the caliper. Use the pliers to remove the cable clip (restraining clip). This step is done only for Grand Prix RPO Z7Us.
5 Hand-tighten two lug nuts to the studs to hold the disc rotor in place while you work on the caliper. Remove the bolt and washer holding the cable support bracket to the caliper. The cable support has the parking brake cable and brake hose attached to it. This step is not done for Grand Prix RPO Z7Us.
6 Use the socket wrench to remove the caliper guide pin bolts. Slide the caliper off of the disc rotor and hang it in the wheel well with a small bungee cord or wire hanger; Don't let the caliper hang from the brake hose.
7 Remove the brake pads and shims from the caliper. Throw away the shims.
Install the new Brake Pads
1 Use the spanner tool to rotate the piston clockwise all the way into the caliper. Make sure the notches on the piston are at the 6 and 12 o'clock positions. There is a boot (rubber seal) around the piston bore. Lift the seal's inner edge and press out any trapped air. Insert the brake pad clips into the caliper support.
2 Apply a thin coat of lubricant to the parts of the inner pad that come in contact with the caliper piston and mounting areas. As you install the brake pads in the caliper support, make sure the wear sensors are downward and at the leading edge of the rotor when the tire rotates. Push the brake pads into the support, holding the metal shoe edge against the spring end of the pad clips. This slightly bends the spring ends and lets the notches engage with the support. This step does not apply for the Grand Prix RPO Z7U.
3 Swing the caliper back into place over the brake pads and replace the mounting bolt. Reconnect the cable support bracket and tighten the bolt to 32-ft.lb. (43 Nm). Remove the lug nuts holding the rotor in place. For the Grand Prix RPO Z7U, Slide the caliper back into place on the disc rotor. Reconnect the parking brake cable. Insert and tighten the caliper mounting bolts to 44 foot lb. (60 Nm).
4 Replace the tire wheel assembly. Lower the car to the ground.
5 Pump the brake pedal a few times to seat the brake pads. Do this before trying to move your car.
6 Add fluid to the master cylinder container to replace any you removed before you removed the old brake pads.
7 Season the brake pads by making only gentle stops when you are driving for the first week
Thanks!

the best thing you can do is go to an autoparts store and purchase a haynes repair manual for your car. cost about $18, but will show you everything you need to know, with pictures.

I'm not sure about your vehicle but some models must be turned as they go back.

Hello, this do it yourself project is very manageable if it is brake pads that you are replacing on your car; if they are disc shoes it may be a little bit harder. In essence a brake job can be done straight out of a auto manual for your car and is not to diffucult as long as you follow good safety procedures while jacking up your vehicle and removing your wheels. First, I would park your car and setting your parking break will make your rear brakes impossible to get off so do not set it. I would however keep this in mind and be very careful working on your car then. I would chaulk your front wheel with a chaulk block or a brick. I would loosen your lug nuts just to break the intial torque I would then jack up the rear of your vehicle and set jack stands under your car in the proper locations. Then systematically, remover your wheel and then the two bolts holding your caliper to the spindle. Carefully, remove the caliper and do not let it hang becuase you will bend your brake line. Remove old shoes, then compress the caliper with a caliper compression tool from your local auto parts store or a c-clamp and a small block of wood. Inspect the rotor for deep gouges, a blue tint, or if you know you have gotten them really hot before I would replace the rotor. Next, install the new brake pads, put rotor back onto spindle and insert bolts back into caliper housing. Repeat for the next side and put the wheel back on and remember to torque your lug nuts to the proper specification. I hope this fixes your problem for you!

Raise the rear of the vehicle and make sure it is securely supported. Remove the rear wheel
Remove the brake hose (A) from the suspension arm by removing the brake hose clip (B).Thoroughly clean the outside of the caliper to prevent dust and dirt from entering inside.Support the caliper with a piece of wire so that it does not hang from the brake se.
Remove the two guide rods (C) and caliper (D) from the bracket.
Remove the pad shim (A) and brake pads (B).
Remove the pad retainers.
Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
Check the brake disc for damage and cracks.
Install the pad retainers.
Check the foreign material at the pad shim (A) and the back of the pads (B).
Contaminated brake discs or pads reduce stopping ability. Keep grease off the discs and pads.
Install the brake pads (B) and pad shim (A) on the caliper bracket. Install the inner pad with its wear indicator (C) facing down ward.
If you are reusing the pads, always reinstall the brake pads in their original positions to prevent a momentary loss of braking efficiency.
Rotate the caliper piston (A) clockwise into the cylinder, the align the cutout (B) in the piston with the tab (C) on the inner pad by turning the piston back. Lubricate the boot with rubber grease to avoid twisting the piston boot. If the piston boot is twisted, back it out so it is positioned properly.
Install the brake caliper (D).
Install and torque the guide rods (E) to proper specification.
Install the brake hose (F) onto the suspension arm with the brake hose clip (G).
After installation, check for leaks at hose and line joints and connections, and retighten if necessary.
Depress the brake pedal several times to make sure the brakes work, then test-drive.
Engagement of the brake may require a greater pedal stroke immediately after the brake pads have been replaced as a set. Several applications of the brake pedal will restore the normal pedal stroke.
