To access front and rear disc brake assemblies, remove the wheel lug nuts, then raise then support the car on jackstands and subsequently remove the wheel. Further on, to release the disc for access lift off the brake caliper without disconnecting the brake hose and secure this part provising the hose in loop wire, do not twist this hose. Looking the disc surface for score marks and damage; minor grooves are normally present but deep score marks that are in excess of 0.015 inch will require disc removal and refinishing by an automotive machine shop. Check the top and bottom of the disc and if pulsating occur during this braking assume disc runout. For runout control, on a disc, fix a dial indicator about half an inch of from the outer edge and rotate it, the zero pistol should not exceed the allowable limit of runout; if it does, refinish the disc. If can want a smooth flat disc to avoid brake pedal pulsations then it is recommended to resurface brake discs and if not then de-glaze the surfaces by rubbing with emery cloth or sandpaper in circular or swirling fashion. Make sure that the disc has not been machined below the minimum refinish thickness that is embossed on the inside of the disc and is measured with a micrometer at three or four positions one half inch from the edge. If it is tight to remove the disc from the hub then place a wooden block on the rotor and give light blow through the hammer so that the disc become free from the stickiness. For installation the steps are to reverse the removal process and fix the caliper, followed by the wheel with the nuts tightened. Bring the vehicle down to the ground then apply handbrakes, further tighten the lugs nuts to the required torque then pedal the brake several time so that the
Brake Pads make contact with the disc. Bleeding is only needed if the brake hose was disconnected from the caliper; to make sure the brakes are working properly before returning to normal use.
