Inserting the thrust plate
8. Hold the thrust plate in position by hand against
the adjustment screw. Insert the Torx 55 socket
into the reset shaft and rotate carefully anti-clock-
wise. Carefully engage the thrust plate thread into
the thread of the adjustment screw. Ensure that
the thread does not become damaged when rotat-
ing. If the thread becomes tight or locks, rotate the
reset shaft clockwise to release the thrust plate,
then try again. A clicking sound will be heard and
felt when rotating the reset shaft anti-clockwise,
9. Once the threads are engaged, ensure that the
thrust plate guide pins correctly locate in the brake
calliper apertures.
10. Continue to retract the thrust plate until the dis-
tance between the thrust plate inner pad face and
the brake calliper outer pad face is smaller than
70 mm,

11. Assemble SAF special tools P/N 4 434 3887 00
and P/N 4 434 3888 00 and insert them into the
brake calliper end of the adjustment screw bel-
12. Firmly press on the special tool with equal and
parallel force so that the adjustment screw bellows
is pressed into position within the brake calliper.
13. The special tool can be removed, rotated and then
reapplied to aid the equal and parallel seating.

Thrust plate bellows seated correctly/incorrectly
14. Remove the special tool. Check that the bellows
are correctly seated in the brake calliper,
. Double check that the bellows are cor-
rectly positioned on the thrust plate,
Failure to seat the bellows correctly will compro-
mise the service life of the brake!
15. Retract the thrust plate fully to its inner position by
manually rotating the reset shaft anti-clockwise.
A clicking sound must be heard and felt when
retracting. The inner thrust plate position must be
distinct. The tightening torque must not exceed
20 Nm.
Danger!
The de-adjust position must not be maintained. In
the de-adjust position, the adjustment function is
overridden.
