How to Repair the Brake Rotors on a 1985 Chevrolet S10

Chevrolet S10 brake rotors are steel discs. A caliper fits over the rotor with a brake pad on each side. When you press the brake pedal, the caliper squeezes the pads on each side of the rotory and the truck stops. If these rotors are damaged, the will use up the brake pads very quickly. That's why it's important to check the surface of the rotor for damage each time you replace the brake pads. If there is any scoring, nicks or groove in the surface, you will need to have the rotor resurfaced. It's not a good idea to resurface the rotors more than once or they will get too thin.

Tools Used: Automobile jack, Wheel chocks, Jack stands, Lug wrench, Socket set, Wrench set, Wheel grease, Wire tires, Screwdriver, Pliers, Rubber mallet

Repair the Brake Rotors

Place the wheel chocks behind the rear tires. Jack the truck up with the automobile jack. Place a jack stand under the truck near the jacking point and raise it up to the frame.

Remove the wheel from the truck using the lug wrench. Remove the brake caliper using a socket and ratchet to loosen the retaining pins, and secure it to the strut with a wire tie. Do not let the caliper hang loose or you will damage the brake line by stretching it.

Remove the rotor from the wheel assembly by pulling it off. If it does not come off easily, hit it several times with the rubber mallet to loosen it up.

Place the new rotor on the wheel. Attach the brake caliper to the wheel and tighten the retaining pins with the socket and ratchet. Put the wheel back on the truck and tighten the lug nuts with the lug wrench.

Remove the jack stand from under the truck and lower the vehicle back to the ground. Repeat the process on the other wheel.

Tips & Warnings

The wheel bearings are easy to remove when the rotor is off. Consider cleaning and repacking them if they have been on the truck for a long time.

Older brake pad linings may contain asbestos fibers. Handle them with care and never sand or grind the linings.
