Yes,this is true of my 70 Dart.It came equipped with 318/904 and 8 3/4. The brakes were manual drum and are 10" all the way around.It actually stopped O.K! It did not like braking down a 10 degree slope with a trailer on the back.The brakes were smoking when we finally got it to stop...
Drums never warped though. The shoes did crack however.
