Could someone measure the outside diameter of the R11 Cardan brake drum? My mechanic added an extra outside sleeve and he made it too big...it only contacts the brake pads on the very outside of the pads-no contact in the middle. I'll need to turn it down so it works.

on my R16 I get about 118 mm but it is hard to measure in situ on the bike.I will take it apart if you can not get a more definitive answer

From one Barry to another,

From one Barry to another, thanks for taking the measurement for me.
So far I've gotten answers ranging from 119-121mm. and yours looks like it might be 118mm. I'll probably just pick a mid-measurement and match the drum to the new brake pads-they only last about six months anyway...
