And, as I learned on a '39 Olds in '54, the drum can split, leaving you
with no brakes. I was 16 yo when I bought the Olds for $50. My Dad
insisted that we get the brakes & steering up to par before I drove it.
That included having the drums turned at the local machine shop. Almost
the first stop sign my teenage self and best buddy came to, doing probably
'way more than the speed limit, I had to do the teen-stop for the sign and
the city bus on the cross street. When I got on the brakes, nothing
happened before the pedal hit the floorboard. I managed to swerve around
the corner and miss the bus. The curb finally stopped us. The shop had
over-turned the drums, allowing one of them to split all the way around the
circumference and across the freed band.
Needless to say, I've been very careful about turned drums for the past 66+
years!
