2. Use the Torx 55 socket to manually rotate the
reset shaft clockwise in order to release the thrust
plate (A). Continue extracting until the thrust plate
unscrews fully and becomes detached from the
adjustment screw, see ► Fig. 49 . The point at
which the thrust plate becomes detached is when
the gap between the thrust plate inner pad face
and the brake calliper outer pad face becomes
smaller than 52 mm. Be careful when removing
the thrust plate not to damage its internal thread or
the external thread of the adjustment screw.
3. Once the thrust plate becomes detached from the
adjustment screw, pull off the adjustment screw
bellows from the thrust plate and brake calliper by
hand. Do not use any tools for this removal be-
cause damaging the mating surfaces could cause
water penetration leakage or seal corrosion upon
re-assembly!
5.4.3 Cleaning
Caution!
● Use a vacuum cleaner to clean the surfaces. Do
not use compressed-air.
● Take care when using chemicals and/or cleaning
tools (e.g. knives, brushes, etc.). This to avoid
damage or displacement of hoses, seals and
other components.
● Ensure that dirt and impurities do not enter the
opening for the adjustment screw!
Fig. 50 - Clamping device for the thrust plate
Clean the thrust plate, the adjustment screw and
the adjustment screw bellows mating surfaces in the
brake calliper. Ensure that the components are free
from dirt, dust, debris, moisture and corrosion.
1. Fasten the thrust plate securely in a vice with soft
jaws, see ► Fig. 50 . Do not over tighten or dam-
age the thrust plate whilst clamping!
2. Clean the internal threaded surfaces of the thrust
plate.
3. Ensure that the contact surfaces between the
thrust plate and the bellows are clean and free
from dirt, moisture and corrosion.
Caution!
Where indicated, use SAF special tools only!

4. Using SAF special tool P/N 4 434 3886 0 (C),
press the adjustment screw bellows (A) into posi -
tion on the thrust plate (B), see ► Fig. 51 . Check
that the bellows are correctly seated in position on
the thrust plate.
5. Clean the external threaded surfaces of the adjust-
ment screw. Ensure that the components are free
from dirt, dust, debris, moisture and corrosion.
6. Apply the grease supplied with the spare parts kit
to the internal thread off the thrust plate and the
external thread of the adjustment screw.
7. Remove the thrust plate from the vice.
Caution!
Do not damage the thread of the thrust plate or
adjustment screw!
