Thanks Barry, Andy, and Brad.
I think it is the rear because I don't feel the pulsation in the steering
wheel, but I DO feel it when I pull up on the handbrake. When just
cruisin', brakes not applied, the car is as smooth as silk (well for a
Spit anyway!).
I have checked for bent wheels by jacking the rear of the car and spinning
them by hand. They seem true visually. (Haven't done it with the car
running Barry..)
If I had a bent wheel, drum, or hub flange, wouldn't the shakin' alway be
there, braking or not?
One thing I maybe should have mentioned: the DPO had run one side without
the two countersunk brake drum screws. The hub center on that side is
galled a bit as a result.
Here is a point-blank question: Has anyone ever had brake drums turned
improperly...off-center?
