This is a fun question!
I don’t know if this could be considered idiotic, but years ago I went to look at a ‘64 Avanti that was for sale locally… The car needed work, however I had definitely seen worse…
What I found strange was the entire disc brake system & the 11” rear drums had been replaced with a complete V8 Hawk/Lark drum brake system…
I drove the car (the original Avanti brake booster was still in place)
Funny thing is, that Avanti stopped BEAUTIFULLY, with very light pedal pressure!!
