Checking brake pads
d Warning:
Have the brake pads replaced
before they wear to the mini-
mum permissible thickness:
have the work performed
by a specialist workshop,
preferably an authorised
BMW motorcycle dealer. Brake pad wear depends on
your personal style of riding.
To ensure reliable operation of
the brakes: do not allow the
pads to wear past the minimum
specified thickness (b Mainte-
nance Instructions, Chapter 2)

Checking brake fluid levelGradual wear of the brake pads
causes the brake fluid level in
the reservoir to drop.
d Warning:
If brake fluid level in the fluid
reservoirs for the front or rear
brakes has dropped below
the MIN mark (
b 33, 34) have
the brake system checked
without delay by a specialist
workshop, preferably an au-
thorised BMW motorcycle
dealer.
Changing the brake fluid
d Warning:
Brake fluid is exposed to
severe thermal loads, and
absorbs moisture from the
atmosphere.
Consequently, the brake fluid
must be changed regularly
by a specialist workshop,
preferably an authorised
BMW motorcycle dealer.

Never permit the brake fluid
level to drop below the mini-
mum level (MIN mark).
 Prop the motorcycle on its side stand
– Make sure the ground is level and firm.  Move the handlebars to the
straight-ahead position
 Check the brake fluid level in

Running in
Running in new brake
pads
d Warning:
New brake pads must “bed
down” and therefore do not
achieve their optimum friction
levels during the first 500 km
(300 miles).
This slight initial reduction in
braking efficiency can be
compensated for by exerting
greater pressure on the lever.
Try to avoid all unnecessary
hard braking during this initial
period.
Tyres: running in
d Warning:
New tyres have a smooth sur-
face. This must be roughened
by riding in a restrained man-
ner at various heel angles
until the tyres are run in.
This running in procedure is
essential if the tyres are to
achieve maximum grip.

Braking
Wet bra kesAfter the motorcycle has been
washed, ridden through water
or ridden in the rain, the brake
discs and pads may be wet (or
iced-over in winter), and may
not take effect immediately.
d Warning:
The brakes have to dry before
they start to bite.
Salt on brakesThe brakes may fail to take
effect immediately if the motor-
cycle was ridden on salt-cov-
ered roads and the brakes were
not applied for some time.
d Warning:
The layer of salt on the brake
discs and pads has to be
worn off before the brakes
start to bite.

Braking
Dirt or mud on brakesWhen riding on muddy roads,
the brakes may fail to take
effect immediately because of
dirt or moisture on the discs or
brake pads.
d Warning:
The brakes must first be
applied until the discs and
pads are clean.
Dirt on the brakes increases
the rate of pad wear.
Oil and grease on brakes
d Warning:
Brake discs and pads must be
free from oil and grease.
d Warning:
If the brake lever can be moved
right to the limit of its travel, this
indicates a mechanical or hy-
draulic fault. The brake system is
defective.
Immediately consult a specialist
workshop, preferably an author-
ised BMW motorcycle dealer.
