(bleeding the pressure accumulator).
-
Make sure that the electrical connector has been pulled off at the pressurizing pump (pump unit).
-
Fill reservoir with fresh brake fluid up to the upper edge immediately after fitting the components.
Connect bleeder device to reservoir.
Block overflow hose (vent) with hose clamp. Switch on bleeder device.
Bleeding pressure approx. 1.5 bar.
Note
While the bleeder device is connected, the brake pedal must not be depressed as the return line may otherwise be pushed out of the rubber plug
of the brake booster.

Continue by bleeding the pressure accumulator.
Bleeding the Pressure Accumulator: 2nd Step
-
If step 1 has not been carried out, release any residual accumulator pressure as follows: Pull off the electrical connector from the
pressurizing pump (pump unit) and open bleeder valve at the pressure accumulator slowly with the recipient bottle remaining connected.
Make sure bleeder hose remains in place.
Caution:
A pressure of up to 180 bar is present at the bleeder valve of the pressure accumulator. Open bleeder valve very carefully. Make sure the
bleeder hose is safely in place!
Wear goggles and protective gloves!
-
Unless this has already been done (if the system was already depressurized), connect recipient bottle to pressure accumulator bleeder
valve and open valve.
-
Set ignition key to position 1 (required to start pump operation).
Connect electrical connector to pump. As soon as no bubbles are visible anymore at the transparent bleeder hose of the recipient bottle,
disconnect electrical connector and close bleeder valve.
Note
If the filler and bleeder device has not yet been connected, check fluid level of reservoir between the individual bleeding operations and top up
with new brake fluid if required.
-
Fill pressure accumulator completely (bleeder valve closed). Connect electrical connector. As soon as the pump has switched off
audibly, pull off electrical connector and release pressure completely at bleeder valve of pressure accumulator. Open bleeder valve slowly
