The Chevrolet Uplander comes standard with four wheel disc brakes composed of iron, and you will know that they need to be replaced if your Uplander tends to steer any time you apply the brakes. You will want to purchase rear disc brake rotors that are vented with an 11.69-inch diameter. In addition, be sure to replace the rear disc brake rotors on both sides. Still, replacing the rear disc brakes of your Uplander is an easy task if you plan ahead and have all the necessary tools required for a proper installation.
Disc Brake Removal
Loosen the lug nuts on the wheel with a torque wrench. After loosening the lug nuts, raise the Uplander with a jack and secure it on jack stands.
Remove the wheel first; underneath the wheel you will find the caliper. Remove the caliper's mounting bolts first then remove the caliper from the steering knuckle.
Pull out the brake pads and any shims.
Inspect and clean the caliper with brake cleaning spray. Check it for wear and tear. If it is damaged, replace it. Add caliper lube to the bolts and sliders inserted into the caliper. This will prevent future damage.
Remove the rotor by detaching the grease cap, cotter pin, nut, washer and outer bearing from the spindle. You should be able to slide the rotor right off of the spindle. The grease cap covers the cotter pin; so once it is removed, all you need to do is pull up on the cotter pin to release it. The nut, washer and outer bearing will slide right off. Be careful with the spindle. You should be able to run your fingernail across its surface without the nail catching on anything. In fact, the spindle should be completely smooth. If it is not, then you will need to replace it. After you remove the rotor, be sure to repack the bearings with fresh grease. This can be done with either a "bearing buddy" tool or by hand.
Slide the disc brake rotors back onto the spindle, being careful not to damage the spindle. Reinsert the outer bearing cone, washer and nut. Push the cotter pin back into its proper place and cover it with the grease cap.
Reinstall any shims you may have removed.
Spray brake quiet lubricant onto the backside of the brake pads then install the brake pads onto the caliper.
Apply anti-seize grease to the bolt threads of the caliper before reinstalling the caliper in its original position.
Lower the Uplander onto the ground with the jack and insert the lug nuts, tightening them snugly with the torque wrench.
