That can be done by removing the wheel lug nuts, lifting the car and placing it on supporting jack stands before carrying out the removal of the wheel. Subsequently, first, take off the brake caliper, and the caliper mounting bracket if it is possible to do so without disconnecting the brake hose. As for the caliper bolts, they should be loosened and, after that, the caliper should be suspended with a piece of wire but no pressure on the hose should be applied. Light score marks are acceptable in a disc, moderate and deep score marks, those greater than 0.015-inch (0.38 mm) thickness require disc removal and refinishing. Look at the bottom and top of the disc, and sometimes the outer ring as the wear can be so bad that it can result to replacement. If pulsating is felt during braking, then the possibility of disc runout is equally high and it is recommended that the wheel bearings should be well set. For checking the disc runout, place a dial indicator around 1/2 inch from the outer edge of the disc, and the reading should not exceed the permissible limit; if it exceeds the limit the disc requires refinishing. Expert advise for the brake discs to perform at optimum, and where they have not been resurfaced, deglazing has to be done with sand paper or emery cloth in circular motion. The disc must not be machined below the minimum thickness for refinish as determined by micrometres. In the case of hub/disc removal, therefore, one loosens two lug nuts as a means of detaching the disc from the hub. Place the disc and hub assembly and set the wheel bearing if necessary then place the caliper and brake pad assembly on the disc placed on the steering knuckle; tightening the bolts of the caliper to the recommended torque. Last, the wheel is installed then lower the vehicle, apply the brake pedal several times to ensure that the brake pads make contact with the disc for inspecting the brake operation before putting the car back to use.
