    Replacement: brake discs – AUDI A8 (4D2, 4D8). Tip from AUTODOC experts:
    Tie the caliper to the suspension or to the body with a wire without disconnecting from the brake hose to prevent depressurization of the brake system.Make sure that the brake caliper is not hanging on the brake hose.Don't press the brake pedal after the brake caliper has been removed.

Check the brake caliper bracket, brake caliper guide pins and boots. Clean them. Replace, if necessary.
