[Healeys] Ford versus Ferrari

[John Rowe]

V8 Supercars in Australia have the rotor and caliper/linings assembly
complete for quick change. They are full of fluid, bled, have quick change
connection on the brake line and can be swapped out in 29 seconds per wheel.

Actually guys, isn't there anyone on the list who was involved in some
way? or has a fiend who was? So that we know what was done.

In the nicest possible way, if you do ask them and put us out of our misery!

All the best,

Peter

PS Yes, I did have a friend who worked on a couple of the GT40s in later
years and was part of the 567 record-breaker resurrection team at one
point, but he appears to have disappeared off the face of the earth!
