Loose the lug nuts of the wheels, lift the car and hold it in place on jackstands. Take the wheel off and attach the lug nuts so that the disc can be clamped to the hub flange, in case the lug nuts do not make contact with the disc after screwing them all the way, place the washers under the lug nuts. Take off the caliper of the brake, but leave the

Removal of caliper mounting bracket-to-knuckle bolts and removal of the mounting bracket is required of front brakes or rear brakes on 2013 and later models. Check visually the disc surface, score marks and other damage; shallow scratches and light grooves are normal, but when there is deep scoring, the disc must be removed and refinished using an automotive machine shop. Look at either side of the disc, extreme wear can require replacement. When pulsating during a brake application, the possibility of disc runout suspect. To verify runout, position a dial indicator at approximately 1/2-inch out of the outer disc edge, position the dial indicator to zero, and turn the disc, the value must not be above the allowable runout limit, and in case it is, the disc must be refinished. Dials indicator notwithstanding, discs must be resurfaced to give a smooth finish and clean up to give a perfectly smooth surface and no brake pedal doubting effect. Unless reproved, wipe off the surface of the glaze with emery cloth or sandpaper in a swirling action. Do not machine the disc to a thickness that is less than the required minimum thickness that has been cast or stamped into the inside of the disc and verify the thickness by use of a micrometer. Unscrew the lug nuts that were used to hold in the disc and remove the disc off the hub. Install the caliper mounting bracket and caliper and place the new disc in place and over the threaded studs. Installing a wheel, lowering the vehicle to the ground and screwing the lug nuts to stipulated level. Squeeze on the brake pedal several times to ensure that the brake pads are in contact with the disc and ensure that the brakes are working well and then test-drive the vehicle.
