For disc refinishing the manufacturer recommends getting a brake on vehicle lathe, but it is not required; service that seems to require the repair facility to have got specialized tool and the vehicle. First, it is advised to turn the wheel lug nut slightly anticlockwise, lift the car and then place it on the jackstands before detaching the wheel. After that, liberate the brake caliper, but do not detach the brake hose; instead, use wire to suspend the hose away from the wheel so no stress is placed on the hose. To be fitted back into position, the lug nuts must be installed with their threads facing down so as to press the disc onto the hub conventionally, spacer washers may be used to make up the required gap. Look at the disc surface to the extent of score marks, crackline and other damages, check that minute scratch marks are nothing out of the normal or usual while deep score mark or crack line may require refinishing or even change of disc. In checking the disc runout, place a dial indicator 1/2 inch away from the outer edge of the disc; if the reading is more that 0.003 of an inch, you should look for pulsation that may mean refinishing, replacement or some distortion in the disc. See that the disc is not machined below the specified minimum refinish thickness and this can be done with a micrometer. For removal, on non-SRT models, unbolt the caliper mounting bracket, align a mark on the disc for reassembly and unbolt the disc, though in the process ensuring that any part that got locked is "released". Before fitting the brake disc use a clean cloth to clean the hub flange and the inner side of the brake disc. Insert back the caliper mounting bracket and fasten the applying bolts for the caliper mount; turn the brake pads back and reposition the caliper. Last, fit the wheel, drop the vehicle and torque the lug nuts before stepping on the brake pedal which will bring the pads to knock the disc gently, check the brake operation before the regular use.
