Mike, I noticed something tonight working on a 73 TR6 that the
on the top of the brake resovor the cap says, "use only clean DOT 3
fluid ", strange that I always thougt this would rot the seals too.
I have always used LMA fluid but have never found any evidence that
DOT 3 does anything other then work. Just to be on the safe side I would
use LMA. Any comments from the TR people, please ck your caps and give
us a line.
