To install the new composite bushing (H) on the
floating bearing side, push the bushing into place
as far as it will go. Ensure correct alignment in the
brake calliper aperture,
or excessive forces are required for this fitting
process. Nor should they be used! If used they
may cause damage! If the bushing is not aligned
correctly, the guide pin and protective cap may not
fit!
Caution!
Once inserted, the guide pin bellows must seat cor-
rectly, i.e. as far as it will go in the intended groove.

Inserting the guide pins
7.
By hand, insert the fixed bearing guide bolt (C) into
the bearing bushing and the floating bearing guide
bolt (D) into the composite bushing,
. The longer guide pin (C) is inserted into the
fixed bearing side. Note that one end of the guide
pins has a machined groove. This side should be
inserted first. No grease is required.
8.
Check that the bellows location ring is fitted
correctly and in one piece. By hand, locate the bel-
lows onto the end of the guide pin. Ensure that the
bellows and the bellows location ring are seated
correctly on the guide pins. Failure to do so may
compromise the slide function of the brake.

rier, the brake calliper and the thrust plate. A wire
brush can be used. Take care not to damage any
of the bellows. Do not grind!
Caution!
Never refit used bolts!
