REMOVING THE REAR
BRAKE CALIPERS
Carefully read p. 44 (MAINTENANCE).
WARNING
A dirty disc soils the pads, with consequent
reduction of the braking efficiency. Dirty
pads must be replaced, while dirty discs
must be cleaned with a high-quality
degreaser.
The use of the vehicle with damaged rims
is dangerous for the rider, other people
and the vehicle itself. Check the conditions
of the rim and have it changed if it is
damaged.
