How to inspect and replace the Brake Disc?

To start inspecting the brakes, loosen the wheel lug nuts and raise the vehicle with jackstands. Next, remove the wheel and then brake caliper making sure not to disengage it from brake hose. Look on disc's surface for any score mark or damage, if deep score marks above 0.015 inches exist disk needs to be removed and refinished. It is also important to check using a dial indicator for disc run-out; ensure that this does not exceed the stipulated limit. Using a micrometer measure disc thickness; make sure it is not less than specified minimum refinish thickness. For removal, on 2003 and later models, remove the caliper mounting bracket and slide off the disc from hub. On 2002 and earlier models, install the disc and hub assembly then adjust your wheel bearings . On 2003 onwards place disc onto hub followed by installation of calipers mounting bracket first then brake pads.
