MAINTENANCE WORK ON CHASSIS AND ENGINE
»
Replacing the front brake pads *
Remove the front wheel (see front wheel chapter).
Press brake shoes apart with a suitable screwdriver to put the brake pistons
in their basic position.
Mount the left brake shoe and fix with screw. Mount the right brake shoe and
tighten the screw to 6 Nm. Mount the lock washer. Align brake shoes, mount
front wheel (see chapter: Mounting the front wheel).
– It is very important to keep the brake disk free from oil and fatty matters.
Otherwise, the braking effect would be strongly reduced.
– After assembly, check if circlips have been fitted correctly.
– Having performed any work on the braking system, one must always actu-
ate the hand brake lever or foot brake lever, respectively so as to ensure
that the brake pads will lie against the brake disk and the pressure point
is established.
– Do not unscrew any other screws on the brake caliper or you will have to
bleed the brake system.
Changing basic position of the brake pedal *
The basic setting of the foot brake pedal can be changed by turning the end
stop roller [3]. Using the push rod [4], the free play on the foot brake pedal
must be set.
Measured on the outside, the foot brake pedal must have 3-5 mm of free play
before the push rod can move the piston in the brake cylinder (to be recog-
nised from the resistance on the foot brake pedal).
If this clearance is missing, pressure accumulates in the braking system and
the brake pads begin to rub. The braking system overheats and can fail com-
pletely in extreme cases.
3-5 mm
Remove the lock washer [1] from the screw as well as fixing screw [2] and
take the brake shoes out of the brake caliper. Clean brake caliper thoroughly
with compressed air.
