e Attention:

The brake fluid must always be visible in the contain-

er, because the piston in the base of the wheel-cir-

cuit reservoir must always be covered by the fluid.

The procedure must be repeated if the fluid drops

below the “min” level.

•

Very gently press the footbrake lever until the

pump just starts up.

•

Open the bleed screw, while topping up the con-

tainer with new brake fluid if necessary.

•

Pump out the brake fluid with virtually no pres-

sure to begin with, then vary the brake pressure.

L 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.

•

When the brake fluid is clear and free of bubbles,

continue pumping until the fluid in the container

just disappears from view.

•

Close the bleed screw.

•

Release the brake and switch off the ignition.

•

Disconnect the brake bleeding device from the

bleed screw.

•

Disconnect the container from the wheel-circuit

reservoir.

e Attention:

After changing and/or bleeding the brakes, always

top up the fluid in the wheel-circuit reservoir to the

correct level in accordance with the instructions.
