Connect container
(No. 34 1 581) to the front wheel-circuit reservoir with
threaded adapter
(No. 34 1 582) and sight glass
(No. 34 1 583). |
|
|
|
Slowly fill the container with fresh brake fluid until it is
approximately 1/2 full. |

Connect the brake bleeding device to the bleed screw of the right
brake caliper, but do not switch on. |
|
|
|
Use a cable tie to secure the hose of the brake bleeding device to
the bleed screw. |
|
|
|
Switch on the ignition. |
|
|
Attention |
|
The front brake lever also applies the rear brakes (integral
brakes). Once the brake calipers and brake pads have been removed,
operating a brake lever could result in the pistons being pushed
out. |
|
Install the brake caliper with brake pads or insert the piston
resetting device. |
|
|
|
|
Very gently pull the handbrake lever until the pump just starts up.
|
|
|
|
Open the bleed screw, while topping up the container with new
brake fluid if necessary. |

Warning |
|
Air can be drawn into the system through the fluid replenishing
hole if the fluid level in the wheel-circuit reservoir is too low;
the system has to be bled again if this happens. |
|
The brake fluid must always be visible in the container, because
the piston in the wheel-circuit reservoir must always be covered
by the fluid. |
|
|
|
|
Pump out the brake fluid with virtually no pressure to begin with,
then vary the brake pressure. |
|
|
|
Note |
|
The higher the brake pressure the faster the fluid is pumped through
the system, which means that the level in the wheel-circuit reservoir
drops all the more rapidly.
|
|
|
Continue pumping off brake fluid until it emerges clear and free
from air bubbles. |
|
|
|
Close the bleed screw. |

|
|
Connect the brake bleeding device to the bleed screw of the left
brake caliper, but do not switch on. |
|
|
|
If necessary, use a cable tie to secure the hose of the brake
bleeding device to the bleed screw. |
|
|
|
The procedure for changing the brake fluid in the left brake
caliper is the same as that for the right caliper. |
|
|
|
When the fluid exits clear and free of bubbles, continue pumping
until the fluid in the container just disappears from view. |
