we didnt chamfer the leading edges an they where "snatchy" for a bit ,that settled down after a bit i think , juddering ,as vespaco says often is looseness ,rim/hubs etc , did you check the main engine bolt for tightness aswell stevie , if alls tight after all its either a brake drum going oval or main mounts giving up the ghost , drums can be skimmed but for the cost a new ones not much more , mounts arent expensive just a pain to do as youve got to drop front of engine to get to them , an also just to look an see , if ya can get a mate to hold front wheel down on centre stand try an wiggle rear of engine sideways ,to see if mounts are sloppy ,
before we get into changing mounts an drums we should have a look inside the drum an see if theres odd wear marks/stiffness ,an chamfer the shoes ,even tho they should of bedded in by now ,
ive judder on my front brake ,but thats from a damaged outer i havent bothered to replace ,it allows cable to flex on the curve giving judder ,doubt if its anything similar on yours but can have a gaze at cable whilst checking the drum out too, H

Well, judders are created by vibration and if the rear brake drum is a bit worn out of round (slightly oval) then non chamfered shoes will 'dig in' and create the judder.
I suspect if you remove the hub you might find one shoe has more contact patch/wear than the other too. Get 'em chamfered and it'll help lots.
