With reassembly of the brake piston basically new gaskets and scrapers have to be used,
since their operativeness is no longer ensured due to wear and damages.
•
Grease the gaskets and scrapers with hydraulic oil (see illustration 17).
!
Oils and greases containing molybdenum disulphite or zinc sulphite additives must not be
used.

!
Inspect the surfaces of the brake piston (component 1.7) and the hole of the sleeve in the
housing (component 1.1) 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 leakages.
•
Insert the brake piston (component 1.7) with the centering sleeve (component 1.11), the centering pin (com-
ponent 1.13) and the pressure cylinder (component 1.8) into the housing and press it against a stop.
A mounting device may be necessary; for that purpose please consult with KTR.
•
Push the set of disk springs (component 1.12) on the centering sleeve (component 1.11) up to the brake pis-
ton (component 1.9).
Lubricate the disk springs properly with Molykote MoS

.
Make sure that the set of disk springs is remounted 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.
•
Insert a new O-ring (component 1.14) between the housing cover (component 1.13) and the housing (compo-
nent 1.1).
•
Screw the screw plug (component 1.25) into all pressure connections.
•
Insert the brake pads (component 2) fully into the brake (subassembly 1).
If you want to insert brake pads after having assembled the brake, it is necessary to disas-
semble the pad retainers (component 1.25) for that purpose (chapter 5.1).
•
Push the washers (component 3.4) on the cap screw (component 3.1).
•
Set the pipe (component 3.2) and the pressure spring (component 3.3) on the pin.
•
Screw the pad retraction sets (component 3) into the housing (component 1.1) against a stop.
