-
Preliminary work: Bleed brakes as usual.
-
To bleed the ABD circuit, the bleeding device remains connected (switched on). Bleeding pressure is approx. 1.5 to 2.0 bar.
-
Connect the Porsche System Tester 2 to the diagnostic socket. The diagnostic socket is located in the driver's footwell (left-hand drive vehicles) or
passenger's footwell (right-hand drive vehicles) near the fuse box. Switch on ignition. In the ABS/TC system, select the "Bleed" menu.
-
Open the rear right bleeder valve (use collecting bottle).
-
Press the Start button on the System Tester. This initiates certain functions in the hydraulic control unit (return pump, switch-off and switch-over
valves are actuated). Bleed until clear, bubble-free brake fluid emerges. In addition (throughout bleeding operation) fully depress (pump) brake
pedal as far as the stop at least ten times. Please note: Double the number of pumping cycles for vehicles with extremely high mileage or for very
old vehicles, and use only half of the master brake cylinder stroke (damage could be caused to the master brake cylinder/primary boots).
-
Close the right rear bleeder valve. Then immediately press Stop button on the System Tester.
-
Switch ignition off and disconnect System Tester.
-
Switch off and disconnect the bleeding device. Correct the brake fluid level if necessary.
