CALIPER REPLACEMENT
8.2.1 - Note identification label, remove adhesive tape
8.2.6 - Check inner boot and ring
Only use original Knorr-Bremse replacement calipers!
8.2.1 The correct choice of caliper must be ensured by
checking the part number on the identification label (arrow

)
(see also Section 1.2).
Note:
The replacement caliper includes seals and guide pins
as well as bolts and bushes for fitting the caliper to the carrier.
Brake pads and wear sensors are not included.
If the replacement caliper is equipped with a potentiometer,
then the connection must be made using the appropriate
mating plug - refer to vehicle manufacturer’s recommenda-
tions.
The caliper guide sleeves should be overhauled with the
respective guide and seal kit (see Section 9 and 10), or the
caliper replaced with the compatible rationalised caliper.
8.2 Fitting Caliper to Carrier -
(Carrier assembled on vehicle)
The guide pins (4) and (5) as well as the caliper bolts (39)
and (40) are highly stressed items. They must be replaced
whenever the caliper (1) is removed from the carrier (2).
8.2.2 Lightly grease guide pins (4 and 5)
8.2.3 Insert the guide pin (4) from inside the caliper to the
outside of the floating bearing.
8.2.4 Insert the guide pin (5) from outside the caliper to the
inside for both fixed and floating bearings (see Section 9.6).
8.2.5 For bearing variant (68f) the guide sleeve is already
pre-installed as part of the Double Roll Bearing.
8.2.6 Check that the inner boot (9) and ring (58) sit correctly
on the guide pin (5) (see Fig.), (see also Section 9.7).
Never hold the caliper with your fingers between caliper
and carrier - there is a risk of injury! Do not fasten any
lifting device to the pad retainer (11), since this could be
damaged.
