Important: After replacing the brake pad friction linings, you should press the brake pedal firmly several times with the vehicle stationary to ensure that the friction linings are in their working position. Brake line union nuts should always be tightened to 14 Nm. Before removing the disc brake caliper or disconnecting the brake line from the brake caliper, lock the brake pedal with a tool (spacer bar) to hold the brake pedal. Brake fluid that has already been used cannot be reused. Tightening torque of wheel mounting bolts: 120 Nm.
