Bonekrosha Posted February 27, 2013 Share Posted February 27, 2013 What year did they begin using disc brakes on NASCAR Plymouths/Dodges ? Quote Link to comment Share on other sites More sharing options...

bbowser Posted February 28, 2013 Share Posted February 28, 2013 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 Quote Link to comment Share on other sites More sharing options...
MAGNUM4342 Posted February 28, 2013 Share Posted February 28, 2013 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. Quote Link to comment Share on other sites More sharing options...
1972coronet Posted March 2, 2013 Share Posted March 2, 2013 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 .

MAGNUM4342 Posted March 2, 2013 Share Posted March 2, 2013 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.

Glued_FIngers Posted April 4 Share Posted April 4 Does anyone know who made the drum brakes they used before 75? They were GIANT 4" brakes weren't they? I saw them on a old cup car in a field that had been turned into a dirttrack car. Who made them? I know Hurst Airheart made the big 4 piston brakes they used for a long time into the 80s and early 90s. But I am trying to find a set of those drums for a vintage road race build Quote Link to comment Share on other sites More sharing options...
