Brake chamber aperture
10. Check through the aperture in the brake chamber
attachment flange for moisture/corrosion,
. It is essential to look inside the aper-
ture and not just on the surface. In the event of
corrosion, further inspection is necessary. In the
event that water has ingressed causing internal
corrosion/damages to the mechanism, replace the
brake calliper to avoid malfunction. For requisite
measures, see "Replacing the brake calliper".

Internal view of the brake chamber
11. On the brake chamber, there must be an internal
bellows (A) on the piston rod,
12. Check that the bellows are complete and not dam-
aged by inspecting around and down the piston
rod shaft. Check for signs of water or corrosion.
These may be a sign that the bellows are dam-
aged.
13.
Check that the external seal flange (B) is correctly
seated, intact and undamaged.
14. Once the inspection is completed satisfactorily,
conclude by reading and following chapter
4.3.9 Checking the guide pin 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.
