Brake system - with BMW Integral ABS
RESIDUAL BRAKING
FUNCTION
If the BMW Integral ABS develops
a fault, a RESIDUAL BRAKING
FUNCTION only is available in the
brake circuits in question.
The RESIDUAL BRAKING FUNC-
TION is the braking efficiency
without the hydraulic servo assist-
ance of the BMW Integral ABS.
Under these circumstances,
therefore, you must apply CON-
SIDERABLY higher pressure to
the brake levers in question in
order to apply the brakes, and
lever travel is longer.
When the RESIDUAL BRAKING
FUNCTION is active, the ABS
function is unavailable in the
brake system in question.
When the RESIDUAL BRAKING
FUNCTION is active, the integral
braking function is partially or
entirely unavailable.
 Warning:
When the RESIDUAL BRAKING
FUNCTION is active, maintain a
defensive riding style and pro-
ceed immediately to the near-
est specialist workshop,
preferably an authorised BMW
motorcycle dealer.

Note:
When the RESIDUAL BRAKING
FUNCTION for the front brake is
active, it is advisable to set ad-
juster A (

35) of the handbrake
lever to position 4.
The RESIDUAL BRAKING
FUNCTION is active under the
following circumstances:
– Ignition off
– Before and during self- diagnosis (

78)
– Fault in the BMW Integral ABS (

81)

Note:
When the RESIDUAL BRAKING
FUNCTION is active for both
brake circuits, the noise of the
pump is no longer audible when
you operate the brake levers.

Self-diagnosis with pull-
away test
The BMW Integral ABS performs
self-diagnosis and a pull-away
test to ensure its operability.
Self-diagnosis is performed auto-
matically when you switch on the
ignition.
 Warning:
Self-diagnosis is not performed
unless both brake levers are in
their fully released positions.
Only the RESIDUAL BRAKING
FUNCTION is available until
self-diagnosis is completed
(
77).
*n depending on national-market
specification
• Release the brake levers, if necessary
• Switch on the ignition
Initially:
