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
