Caliper Guide Pin Seals
5.5.1 The guide pins (4 and 5) are sealed with inner boots

(see section 6.1).
If necessary, repair caliper with suitable service kit (see
Section 1.2 and Section 8).
5.5.3 The rubber boots on the tappets (13) must not have
any cuts/tears or show any other signs of damage (see Fig.).

Note:
The penetration of dirt and moisture into the brake will
lead to corrosion and impair the function of the clamping
mechanism and wear adjuster.
If necessary replace tappet and boot assemblies (see Section 7).
The tappets must not be extended more than
30 mm
,
otherwise synchronisation is lost and the caliper must
be replaced.
