Also to be considered when installing B007 - B680 brakes on ZBA, ZBE and ZBP motors:
1) Fit O-ring (14)
2) Fit brake disc (3)

1) Fit O-ring (14) onto the carrier.
2) Fit brake disc (3).
3) Push brake disc (3) into position.
Noticeable resistance has to be overcome to push O-ring (14) out of the
retaining groove. This point of resistance clearly indicates that O-ring (14) is
correctly fitted in the recess of brake disc (3).
Brake disc (3) may only be moved in the direction of the brake-side end cap
(see "Direction of assembly"). If brake disc (3) is pulled back by more than
1,4 mm, O-ring (14) will roll out of the recess in brake disc (3) (repeat the
process if the disc is pulled back by more than 1,4 mm).
In this case, the damping effect will then no longer be ensured.
