Push the right pedal.
Make sure that :
-all the pistons are retracted on the brake units of the right main gear
-the pistons related to the Greenhydraulic system on the brake unitsof the left main gear extend slowly.on the panel 400VU :
-make sure that the brake Yellowpressure triple indicator 60GG showsno pressure value on RH and LH side.
Make sure that the pistons slowly retract on the two brakes of the left main gear.
