As discussed during our recent phone conversation, ve have reviewed the contents
of our current service
for mention of cautions regarding brake repair.
Ve are not currently providing a procedure for removal of dust from the brake
drums or brake n "g area.
I have noted on the attached copies of our shop manual, the locations that should include a caution regarding asbestos particles.
If you will provide same suggested copy for a caution, ve will insert it in the
next printing. Ve will also incorporate this caution in all future texts, such
as training mmnala mil video tapes, that pertain to the areas where asbestos
dust may be considered harmful.
