5 Maintenance
5.2 Maintenance of the brake / replacement of single parts
Oils and greases containing molybdenum disulphite or zinc sulphite additives must not be
!
used.
Illustration 15: Assembly of gasket and scraper
Inspect the surfaces of the brake piston and the hole of the housing to make sure that they
!
are neither scratched nor damaged, since the surfaces are either ground or polished. Such
kind of damages may cause earlier wear on the gaskets and scrapers and generate leaka-
ges.
• Insert the brake piston (component 1.2) into the housing and press it against a stop.
• Shift the set of disk springs (component 1.6) into the brake piston (component 1.2). Make sure that the disks
are located on top.

Grease the disk springs properly with Molykote MoS
Please make sure that the set of disk springs is mounted in the same arrangement as it was
supplied.
If a new set of disk springs is used, the condition of supply needs to be observed in detail.
• Screw the setting nut (component 1.7) into the housing and set it to the right dimension (see illustration 12).
• Put the opening pressure (see table 2) onto the hydraulic system.
• Hand-tighten the screw with the disk (assembly lock, see illustration 11) into the setting nut (component 1.7).
• Release the pressure from the hydraulic system.
• Insert a new O-ring (component 1.9) between the housing and the setting nut.
• Repeat chapters 4.2 to 4.8.
