Wow, I'm surprised it was that late. Can you imagine Martinsville or North Wilkes in a 73 Charger with drum brakes? Talk about nerves

Brake wear-out was a major problem in those days and probably accountable for at least a third of on track and pit road accidents.

Those early disc brake calipres caused a lot of drag ( by nature of their function ) , which is why 99% of race cars ( Stock Car , 1/4 mile , etc. ) had drums until the early-mid seventies .

Very true John. Even the Petty team tended to shun them except on the smaller tracks. IIRC, they only used disks on the front end, and only onshorter tracks during most of the seventies. On restrictor plate races they continued using drums all the way round.
