Hi Alan,
I just sent a group of photos to Martin of different rotors and caps (I
horde) hoping he can compile them and post on his web site.
The more I look at #3 the more it makes sense that it would fail and
short-out. The little metal tab underneath must be really close to the
rivet internally to this rotor. I concur that these rotors are the weak
ones. During the after-tour from Nelson I handed a new #3 loaner to a
friend when his #3 failed and after 100 miles it too failed. I remember it
well because Bill Bolton got ticked-off and chucked it as far as he could.
In short (pun) shy away from them tiny rotors with the round top rivet and
the little metal tab. If they disintegrate it is obvious but they do crack
and short internally and can still look serviceable stumping even the most
seasoned of Healey tinkerers.
Happy trails,
Tracy

Martin -
I have found that the original Lucas rotors to be quite good and long
lasting, however they tend to wear a bit where they fit on the shaft,
getting a bit wobbly over time... but it works without fail. These are good
rotors if you can find them.
#2 on your list is my favorite rotor and a brown version of this was sold by
Bosch for many many years. This is a good rotor and will probably never
fail you.
#3 and #4 are both pieces of crap and should be tossed in the garbage.
Maybe you can keep them as spares in your tool box, but I wouldn't even want
to keep them as spares, because they can fail within minutes of
installation. Yes #3 is the one with the bad rivet.
