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.
•
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.
•
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.
