Brake-pad wear limit,
rear
1.0 mm (Friction pad only,
without backing plate. Make
sure that the brake disc is
not visible through the bore
in the inboard brake block.)
If the brake disc is visible:
Brake pads worn past the
minimum permissible thick-
ness can cause a reduction in
braking efficiency and under
certain circumstances they can
cause damage to the brake sys-
tem.
In order to ensure the dependab-
ility of the brake system, do not
permit the brake pads to wear
past the minimum permissible
thickness.
Have the brake pads replaced
by a specialist workshop,
preferably an authorised BMW
Motorrad dealer.
