I've looked carefully at the rear suspension on my TR6 with an eye toward
designing a disc brake conversion, but I reached the conclusion that it
just ain't possible. I think the only way, MAYBE, is if you set it up to
run the rotors "inboard" like an E-type... but I just don't see how you
could attach a caliper to the semi-trailing arm, nor can I envision a way
to secure any kind of rotor to the hub housing. Even if you designed an
inboard disc brake set-up, you MIGHT have to design and machine new drive
flanges... flanges that would accept a rotor off of, say, a Spitfire or
something... (just thinking out loud here, folks!) and then the caliper
would have to mount onto the differential somehow, because the diff moves
around a bit and the caliper and brake rotor would have to move with it.
Maybe design a new inner axle shaft seal housing that would also serve as
the mounting bracket for the caliper?
But then you've got the issue of heat generated by the diff and then
conducted to the caliper, and that might blow the whole concept out of the
water. But then, they must've had to deal with this problem on E-type
Jags, right?
