| The SBC system must be deactivated on a mandatory basis using STAR DIAGNOSIS before working on the operating unit or hydraulic unit. Brake pad exchange and brake fluid change must not be carried out simultaneously. Before working on the SBC brake system the sequence of the SBC self-test must be prevented as this leads to the brake pistons being pushed out automatically. When working on the SBC brake system the brake pedal must not be pressed under any circumstances as this leads to the brake pistons moving out automatically. Inadvertent operation of the brake pedal must be prevented reliably by suitable measures. No persons or animals may stay in the vehicle when working on the SBC brake system |
