torque.

After tightening, using an appropriate tool, notch and bend
the ring nut as shown in the figure so it cannot be unscrewed.
The arrow shows the direction of unscrewing the ring nut.

Lock rotation of the wheel hub (3) with the tool 99370317
(4) and tighten the screws (2) fixing the brake disc (1) to the
wheel hub to the required torque.

Position the brake calliper (1) on the flange (3) and tighten
