Girling brake question...
#4
With the Seven systems there is little scope for self servo effect because when one shoe self activates the cam rotation is restricted by the other so the cam cannot fully follow up and reinforce the full self action. Some other makes had two leading shoe mechanical brakes but the linkage was complex.
With a floating adjuster the whole retardation would then be resisted by the cam; a bit much for as already often bent. And probably problems with grabbing.
I gather some have modified the adj end of shoes so these are free to slide instead of being contained by the the anchor pin or round ended adjuster pistons. Moderns are like this and curiously do not drag, but the normal operation is by piston and straright line. With low power Sevens anything likley to drag has to be avoided.
