R 1200 CL
Brake Components and Integral ABS
The BMW fully integral ABS enables the
braking efficiency to be distributed via electronic
control ensuring optimal braking
power is always available on each wheel. At
the same time, influencing factors such as
dynamic wheel load distribution, load and
temperature of the brakes are taken into
account. In addition, the system includes
the antilock function so that a reliable braking
function is available on the motorcycle.
The system’s integrated brake booster
keeps the operating force of the brake lever
low for the rider. With the fully integral variant,
the front and rear control circuits are
connected by integral pistons in the pressure
modulator that the front and rear wheel
brakes are activated automatically when the
hand lever or rear pedal are operated.

The fully integral pressure modulator of the
R 1200 CL is installed beneath the tank.The
brake fluid reservoirs for the front and rear
wheel circuit are located in the pressure
modulator as on all R series bikes. The
brake fluid reservoir for the front control circuit
is located in the hand lever master
cylinder. The rear control circuit reservoir is
connected to the brake pedal master cylinder
via a feed line (green line in illustration).
As with all versions of the Integral ABS, the
modulator control valves are designed to
provide the residual braking function, which
connects the control circuits and wheel circuits
via piston movement (hydraulic over
hydraulic control). This safety feature
ensures adequate brake function if the ignition
is turned off or if the Integral ABS is
defective.
