  Q: How to remove and reassemble the Brake Disc and Wheel Hub?

  A: Remove the caliper and anchor plate assembly. If the caliper and anchor plate are not needing attention, there is no need to disconnect the flexible brake hose from the caliper. Suspend the assembly with string or wire from the upper suspension arm. Carefully remove the grease cap from the wheel spindle using pliers. Withdraw the cotter pin and nut lock from the wheel bearing adjusting nut. Undo and remove the wheel bearing adjusting nut from the spindle. Grip the hub and disc assembly and pull it outwards to loosen the washer and outer wheel bearing. Push the hub and disc back onto the spindle and remove the washer and outer wheel bearing from the spindle. Grip the hub and disc assembly and pull it from the wheel spindle. Carefully pry out the grease seal and lift away the inner tapered bearing from the back of the hub assembly. Clean out the hub and wash the bearings with solvent, ensuring no grease or oil gets onto the brake disc. Clean any grease from the rotor with denatured alcohol or brake cleaner. Thoroughly clean the disc and inspect for deep scoring or excessive corrosion. If necessary, reground the disc, but ensure the minimum thickness is not less than specified. Ideally, install a new disc and clean it to remove the protective coating. To reassemble, grease the bearings and fully pack the bearing cages and rollers. Fit the inner bearing and tap the grease seal back into the hub, ensuring the lip faces inward. Replace the hub and disc assembly onto the spindle, keeping it centered to avoid damage. Place the outer wheel bearing and flat washer on the spindle. Screw the wheel bearing adjusting nut onto the spindle as instructed. Detach the caliper from the upper suspension arm and guide the assembly towards the disc, being careful not to stretch or twist the brake flexible hose. Start by sliding the caliper assembly onto the disc at the lower part and continue installing the assembly.
