How to Replace the Brake Rotor on a 1993 Buick LeSabre


Brake rotors are the steel discs that the brake pads grab onto when you push on the brake pedal. The brake rotors on a 1993 Buick LeSabre are replaced in much the same way as any other brake rotors, using the same tools and principles. Replacement rotors are available at any automotive-parts and supply store and, since a rotor is only found on disc brake assemblies, only the front wheels on a 1993 Buick LeSabre will have rotors.

Tools Used: Tools, Car jack, Jack stand, Lug wrench, Caliper wrench, Brake cleaning fluid, Clean rags, New rotors

Replace Brake Rotors

Jack up the car as you would if changing a flat tire. When jacked high enough so that the tire clears the ground, place a jack stand beneath the frame for added safety. Remove the lug nuts from the tire, the same as if you were changing a tire. Once the lug nuts are removed, pull the tire off and away from the wheel. Use a caliper wrench to remove the caliper. A caliper wrench looks much like a large Allen wrench; they are available at auto-parts and hardware stores. Calipers are what hold the brake pads onto the rotors, so the caliper mounting bolts must be removed. There are two bolts, one each found near the top and bottom on the rear of the caliper.

Remove the caliper assembly off the rotor and set it aside. Then pull the rotor straight off the lug studs. Spray the new rotor with brake cleaning spray to remove any oil from when it was packaged. Once sprayed, wipe the rotor thoroughly with a clean rag. Push the rotor onto the lug studs, then replace the caliper onto the rotor. Tighten the caliper bolts with the caliper wrench, put the tire back on and replace the lug nuts. After tightening the lug nuts down, pull the jack stand out and jack down the Buick. Repeat these steps for the rotor on the other wheel.
