Locate the disc brake assembly on the transaxle. Tighten the centre boly about half a turn. Test. Repeat if necessary. Count turns as you go. If there is insufficient adjustment available, return to starting position, unbolt entire caliper (2 long THIN bolts - use plenty of WD40 and let it soak in overnight. If they break off you have a major strip down to fix it) and replace pads.
