Yes guys and gals that is what I would like to know. When did Disc brakes first appear on mass produced cars and when did they start being used on the early hot rods?? Some people question whether disc brakes are traditoinal on cars been build to say a 60's style of car? I like the look of the hidden discs in the finned drum brake look. I have smallish solid rotors with chrome calipers on the front of the Bucket from a Mk3 Zephyr (English Ford from the mid 60's) and wonder if I have it wrong trying to accomplish that 60's look.
