Sounds like you just made that up, or you were using the most rusted out piece of junk in the universe that you shouldn't have been riding on anyway. I ride around on a 1971 UO-8 with extremely rusted out parts, and can still slide hills no problem. To not know what broke on your bike after a HUGE mechanical failure such as the one described, you probably shouldn't be riding in the first place!
