Vito 109 parking brake adjustment

[reggie]

I have been trying to find out how the heck I can adjust the parking brake on my Vito 109. I have had the rear wheels and disks off, looked under the pedal and just cant find out how.

Does any of our esteemed crowd have a notion?
Thanks
Reggie

The adjustment is made on the inboard shoes at the rear.

Getting the disks off is no problem but is the adjustment through a toothed wheel, or something else?
