The brake rotors on the 2003 Chevrolet Impala are the main component in stopping the car when the brakes are applied. The brake pads slide against the brake rotor until the car comes to a stop. Once the brake pads wear down, they will start to leave grooves on the facing of the brake rotor. When the brake rotors become grooved, they will need to be replaced.

Park the 2003 Chevrolet Impala on a level surface and set the emergency brake.
2Jack the front of the Impala up and place jack stands under the frame rail behind each front tire. Lower the Impala onto the jack stands.
3Remove the driver's side tire with a lug wrench. Turn the lug nuts counterclockwise to loosen and remove the lugs.
4Slide the wheel off of the hub. Remove the upper and lower caliper mounting bolts on the back side of the caliper with a 3/8-inch drive ratchet and a 9/16-inch socket. Turn the mounting bolts counterclockwise to loosen and remove.
5Slide a flat head screwdriver between the brake pads and the caliper piston. Pry the brake pads toward the caliper piston until the piston is fully compressed.
6Slide the brake caliper off of the top of the brake rotor. Hang the brake rotor up on the strut or the frame with a clothes hanger so that it is not hanging from the brake line.
7Slide the rotor straight off of the wheel hub. The brake rotor on the 2003 Chevrolet Impala can be pulled straight off of the lugs.
8Slide the new brake rotor over the lugs and onto the wheel hub.
9Unhang the brake caliper and slide it over the top of the new brake rotor. Screw the upper and lower mounting bolts back in and tighten them down with the ratchet and 9/16-inch socket.
10Slide the wheel back onto the hub assembly and screw the lug nuts back on. Turn the lug nuts clockwise to tighten.
11Jack the Impala up and remove the jack stands from under the car. Crank the Impala and pump the brakes to seat and adjust the brake pads to the new brake rotor.
