Andy I asked a similar question back in 2002 and others continued the
discussion. I'll paste the relevant reply here in /italic/ and then
comment at the end.
/I had a few folks ask me to get back with them if I found anything on
the rotors, therefore I'll post the answer. Below is a definitive
response from Dan. My new favorite parts store, owned by two brothers
who are not on computer and still have all sorts of catalogs for parts
going back to the 60s looked up the rotors and told me the very
technical answer, "book says throw out at .310". I have not researched
the drums yet... actually, I still haven't got them to let go of the
hubs, but I'm in no rush. Matt -----Original Message----- From: Dan &

Subject: Re: Brake rotor min. thickness Matt, The new rotors are .500
inch and the minimum is .375 inch. The data came from a factory service
bulletin. Hope this helps. Dan /
Today's (5-2-22) comment: I took my rotors to Pep Boys back in 2002 and
the guy there (a Triumph owner) turned them for me. I can't remember if
they were already in the .440-.450 range or that is what they were
turned to. At the time the list said the .375 size (much less the .310
size) stated in the email from Matt was said to be way too thin (I would
agree). And, I'm not sure where the person named Dan got this factory
service bulletin from? As a general rule .040-.060 under original size
is a common number. Anyway, I had a second set of rotors and I dashed
them over to PB the same day thinking this might be the only chance that
someone will turn them. Others had indicated that without a modern spec
available many places refused to turn them. I don't know the
availability of new rotors. This is a "do at your own (and others) risk"
thing but measure your rotors then find a rotor that is similar in the
size you measure. Tell them they are rotors for that similar sized
vehicle. It may be the only way you get them turned because they likely
lack data on the Tiger and might say No! Just remember that this is a
compromised means that limits the braking capability but if no other
rotors are available it seems better than nothing.
