1968 Chevrolet Chevelle Brake Upgrade - Whoa, Chevy! Photo Gallery
Slide the new 13-inch rotor over the wheel studs, and hold the rotor in place with a few lug nuts. This will properly position the rotor for the installation of the brake caliper. Note that the rotors are marked "L" and "R" for left and right. Double-check that you're putting the right rotor on the right wheel.
