How to Remove Rust on C5 Corvette Rotors

Created from metal alloys, the brake rotors on your C5 Corvette are prone to developing surface rust, especially if they are left exposed to the elements. Moisture that develops on the surface of the rotor can cause surface rust to develop as well. In most cases, removing rust is only a matter of driving your vehicle in a normal manner, since application of the brake pads can remove a large amount of surface rust. However, you will need to remove the rotors in order to remove rust formed along the edges of the rotor.

Instructions

1

Apply the C5 Corvette's brakes during normal driving. Two to three brake applications at normal speeds should help remove surface rust from the face of the rotor. However, this will not remove surface rust near the rotor hub or along the outer edges of the rotor. In order to remove rust from other areas, you will have to remove the rotor.

2

Park the C5 Corvette on a flat surface and loosen the lug nuts with a lug wrench. Raise the vehicle off the ground with a floor jack and support the vehicle with jack stands. Finish removing the lug nuts and pull the wheel off of the hub

3

Use a ratchet and socket to remove the four bolts holding both the caliper and caliper mount in place. Pull the rotor off of the hub and place it on a flat work surface.

4

Use a Dremel tool with a wire brush or sanding disc attachment to remove surface rust from the outer edges and inner surfaces of the rotor. Remove any remaining debris from the rotor with brake cleaner and a shop rag. If the rotor appears pitted with rust, consider having it replaced with a new rotor. Repeat this step for the other rotors on the C5 Corvette.

5

Slide the rotor back onto the hub. Reattach the caliper and caliper bracket onto the hub and remount the wheel. Place the lug nuts on the wheel and hand-tighten them. Remove the jack stands and lower the vehicle to the ground, and then tighten the lugs with the lug wrench.
