How to Replace Brake Rotor on 1997 Chevy Lumina

The brake rotors on the Chevy Lumina are made of cast iron. When your brake pads wear too thin, the rivets will begin to cut grooves into the surface of the rotor. The rotor is also subject to cracking, and can warp if it gets very hot and then gets wet. In any case, when damage occurs to the brake rotor, you need to replace it. This is a project you can take care of in your garage or driveway.

Instructions

1

Park your Chevy Lumina on a level surface and turn off the key. Open the hood and drain two-thirds of the brake fluid using the turkey baster. Place the fluid in the drain pan for recycling.

2

Set the wheel chocks behind the rear tires of your Chevy Lumina. Raise the car with the automobile jack on the side that you will be starting with. Place a jack stand under the Lumina near the jacking point and raise it to the frame. Remove the lug nuts with the lug wrench and take the wheel off the car.

3

Remove the brake caliper by loosening the retaining bolts with a socket and ratchet. Push the caliper piston back into the housing by placing the jaws of the C-clamp over the back of the caliper and the back brake pad. Twist it closed until the piston is fully within the housing. Secure the caliper to the strut using a wire tie. Do not allow it to hang or you will damage the brake line.

4

Remove the rotor from the wheel assembly by pulling it off. Thoroughly clean the wheel assembly with a wire brush. This is necessary, because dirt and debris will keep the rotor from sitting flush and it will cause the rotor to wear unevenly.

5

Place the new rotor on the wheel assembly. Cut the wire tie securing the caliper to the strut using the pliers. Place the caliper onto the mounting bracket. Tighten the retaining bolts with the socket and ratchet. Do not over-tighten the bolts or you will strip the threads.

6

Place the wheel on the Lumina and tighten the lug nuts with the lug wrench. Remove the jack stand from under the car. Lower the vehicle to the ground. Repeat the process on the other wheel.
