ok ok
this is the way i've done it...
Fitted up new URAS brake shoes which fit straight in.
unwound the handbrake level completely
put disc on hub (over shoes)
adjusted the little cog at the bottom both sides until wheels wouldnt turn, and then wound a little off
put wheels back on
lowered down
adjusted (tightened with 10mm) at handbrake lever (and again...and again)
still not 100% happy with my result - is this how everyone else has done it?
thanks
