My 68 GTO has all drum, power brakes. Everything new, great feel at the pedal, everything properly installed.

I was wondering what the typical break-in time is for the shoes. Driving nothing but late model vehicles for the last 45 years I was a bit surprised at the lack of braking power when first moving the car around. Brakes "work", pedal is hard, booster seems to be working.

I built drum brakes for vintage racing motorcycles for years, arc'ing the shoes on a lathe for the fastest possible bed-in for the shoes, rebonding new aggressive compounds on old shoes, tuning the linkage etc. But I'm not an expert on the behavior of OEM type street brakes.

The car has only moved maybe a couple hundred yards, up and down my drive a few times, across the street and up and down that drive ... and they have gotten better.

Can I expect them to improve with actual on the road time an braking from more than 15 mph?

Thanks
