Scroll thru that and you'll eventually come to a drawing of the brake set up.
CAUTION****DO NOT CLICK ON GUZZI GIRLS**** or you will be distracted for a minimum of a half hour. Especially do not click on Valentina!!!
As far as adjusting the brakes, there've been instructions posted, possibly here or maybe it was on the MG National Owners Club (MGNOC) website. I'll see if I can dig them up if you can't find them.
