Check that brake hoses are
correctly routed to avoid chafing or
kinking.
Inspect unions and brake calipers
for signs of fluid leaks.
Inspect rigid lines for corrosion,
dents, or other damage.
Inspect flexible hoses for cracking.
Replace faulty hoses or lines, see
340 Brakes.
WARNING!
Incorrect installation or
overtightening hoses, lines, and
unions may cause chafing or
leakage. This can lead to partial or
complete brake system failure.

Parking brake, checking

The parking brake system is
independent of the main braking
system and may require periodic
adjustment depending on use. Adjust
the parking brake if the brake lever can
be pulled up more than 8 clicks. Check
that the cable moves freely. A
description of the parking brake and
parking brake adjustment can be found
in 340 Brakes.
Note:
The parking brake may lose some of its
effectiveness if it is not used frequently.
This is due to corrosion build-up on the
parking brake drum. To remove
corrosion, apply the parking brake just
until it begins to grip, then pull the lever
