Here's the set-up I originally made for my TR3. However, Randall correctly pointed out that if I used the same size cylinders as original, that my braking forces at the wheels would be less and that I'd have to go to smaller bore masters. I calculated that about two 9/16" cylinders would provide the same force as one 3/4" cylinder. They don't seem to make them in that size, 5/8" is the closest. I abandoned the project for now, but would like to return to it one day.
I wonder what size cylinders Revington is using?? Probably 5/8". Since the TR3 has a pretty heavy pedal as it is, I don't know if I want to go to that size.
Edit: BTW, the Revington setup for the TR3 has you widening the opening in the firewall to accept their set-up. I managed to squeeze it all in without doing that, however, I would then need another remote reservoir. Not a problem, however, the other problem would be brake bias. I don't have a lot of room between the two brake master on the bias rod, so it would be tricky to get that just right. A lot of trial and error, but it could be done. ANy one know where to get 9/16" or even 1/2" cylinders???
