Looking at the brakes on my Vincent I noticed some differences. Just one of the 4 backing plates has 4 equi-distant holes around the outer edge. Also I seem to recall mention that there should be/ is desirable for water drainage holes in the brake drums themselves.
So - when did these drain holes come into being at the works - frame or engine number?
And if they are not there today, should they be added? If yes where and what size?
