4.3.10 Checking the thrust plate bellows
Danger!
Wear respiratory protection in order to avoid inhaling
particles which can be hazardous to health! Brake
pad wear produces dust which can cause lung dam-
age!
Caution!
●
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.
●
Use a vacuum cleaner to clean the surfaces. Do
not use compressed-air.
●
Never use an impact wrench or similar to rotate
the reset shaft. This may damage the disc brake
mechanism! The maximum torque is 20 Nm.
Note:
Do not over adjust/extend the thrust plate whilst car-
rying out the inspection. Over adjustment/extension
may cause the thrust plate to disengage from the
adjustment screw and if done unintentionally may
cause damage to the thrust plate bellows! The min.
distance between the brake calliper and thrust plate
is 60 mm.
