Unless you have a hydraulic press, don't attempt this in your basic garage or driveway.

Did you machine the rotors?

New pads only go on with new or machined rotors

Did you remove ALL rust on hub face,both sides of
rotors & back of wheel,caliper & pad abutements & use
anti-seize on all sliding surfaces?

Did you dial indicator the new wheel hub after installing
for turning true?

Removal & Installation


NOTE Using a brake pedal holding tool, depress the brake pedal past its first inch of travel and hold it in this position. This will isolate the master cylinder from the hydraulic brake system and will not allow brake fluid to drain out of the reservoir while the brake lines are open.

1. Before servicing the vehicle, refer to the Precautions section.
2. Remove or disconnect the following:
   
   Negative battery cable Rear wheels Banjo bolt retaining the brake hose to the caliper. Be sure to plug the end of the brake hose or cover it with a plastic bag to prevent contamination from entering the hydraulic system. Caliper guide pin bolts Caliper assembly from the brake adapter by rotating the bottom of the caliper away from the rotor, then lift the caliper with the pads away from the adapter abutment Brake pads by pushing (outboard) or pulling (inboard) from the caliper fingers and piston

Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

REMEMBER TO REPLACE THE PADS AS WELL, NO USED PADS ON NEW ROTORS.

Raise the vehicle and support on jack stands. Remove the wheels. Place the drip pan under the caliper. Loosen the 10 mm bleeder screw on the top of the caliper.

Step 2 Spread the brake pads apart with the common screwdriver. Place the screwdriver in the slot in the center of the caliper where the pads can be seen. With the nose of the screwdriver, pry between the rotor and the pad and pull the caliper outward toward you. The piston is being depressed into its housing as the caliper is pulled out. When the caliper comes to its limit outward, push the caliper back away from you and insert the screwdriver into the inside pad between the pad and the rotor. Once again pull the screwdriver toward you until the caliper piston is compressed into its bore.

Step 3 Tighten the 10 mm bleeder screw. Remove the caliper and support it where it is not hanging on the brake hose. Letting the caliper hang on the brake hose will damage the hose and cause brake failure.

Step 4 Remove the caliper support if it interferes with the removal of the rotor. Some vehicles don't require the removal of the support. Remove the rotor by pulling it off. If it is stuck, hit it with a hammer a few times between the studs.

Step 5 Install the caliper support and caliper in the reverse order they were taken off. Install the wheels and let the vehicle down. Check the brake fluid and fill as necessary to the proper level.

Step 6 Start the vehicle and pump the brakes very slowly until you have a high pedal. Remember that by expanding the calipers they have to re-adjust. You will not have any braking when you first start the car. Do not try to move the car until you have pumped the brake pedal sufficiently to feel a firm pedal.
Rear-Wheel-Drive Vehicles

Step 1 Raise the vehicle and support on jack stands. Remove the wheels. Place the drip pan under the caliper. Loosen the 10 mm bleeder screw on the top of the caliper.

Step 2 Spread the brake pads apart with the common screwdriver. Place the screwdriver in the slot in the center of the caliper where the pads can be seen. With the nose of the screwdriver, pry between the rotor and the pad and pull the caliper outward toward you. The piston is being depressed into its housing as the caliper is pulled out. When the caliper comes to its limit outward, push the caliper back away from you and insert the screwdriver into the inside pad between the pad and the rotor. Once again, pull the screwdriver toward you until the caliper piston is compressed into its bore.

Step 3 Tighten the 10 mm bleeder screw. Remove the caliper and support it where it is not hanging on the brake hose. Letting the caliper hang on the brake hose will damage the hose and cause brake failure.

Step 4 Remove the bearing cap in the center of the rotor. Remove the cotter pin. Remove the large nut that retains the bearings and rotor. Wobble the rotor with your hands and the front bearing will come out.

Step 5 Reinstall the spindle nut with just a few threads. Grabbing the rotor with both hands, pull the rotor off with slight down pressure and with a quick ****. The spindle nut will grab the rear bearing and seal as you pull the rotor off and come out at the same time.

Step 6 Install the bearings into the new rotor. Grease the bearings first and install the rear large bearing then install the grease seal with the hammer. Install the rotor on the spindle and insert the front small bearing followed by the large washer and the retaining nut.

Step 7 Tighten the retaining nut just until there is no longer any freeplay then tighten an additional 90 degrees. Do not over tighten the retaining nut as it will not allow the bearings to expand and they will wear out rapidly. Install the cotter pin.

Step 8 Install the caliper support and caliper in the reverse order they were taken off. Install the wheels and let the vehicle down. Check the brake fluid and fill as necessary to the proper level.

Step 9 Start the vehicle and pump the brakes very slowly until you have a high pedal. Remember that by expanding the calipers they have to re-adjust. You will not have any braking when you first start the car. Do not try to move the car until you have pumped the brake pedal sufficiently to feel a firm pedal

The problem might have already been there,the steel wheels are making it noticeable,because they don`t cool down as quick.Most likely is the calipers sticking,or you have a set of high dollar brake pads on the vehicle,and they are heating the rotors up.The high dollar pads are a very hard composite pad witch produce a lot of friction,and heat as a sort of side affect.
