Where is the hand brake adjustment on a citroen dispatch?

My Handbrake adjuster is situated on the left hand side (left hand drive van) just underneath van, where the handbrake is on floor. Jack up rear of vehicle, support both sides on axle stands. Apply handbrake 5 clicks, wheels should be locked at this point. If not, adjust nut on adjuster until wheels are both locking. Release brake, wheels should turn freely, no binding. Hope this helps.
