Rollo, I think that just a little more information is required:-
1. Has the noise and vibration just started?
2. What linings are you using?
I ask this as my own car, (a 1933RP like yours) began to make a serious graunching noise on braking (which I referred to as 'railway brakes' as the noise reminded me of the noise from truck brakes in shunting yards). It first appeared when the brakes had got wet and then were drying out. It then got to be there more often, not all the time, but especially when stopping the car in reverse. Checking the brakes revealed nothing amiss, so I lived with it.
Very recently, I decided to reline the brakes as the rears were beginning to get a bit thin. The material fitted when I had the car was the old type rope linings. I replaced them with more modern linings from one of our cherished suppliers and, Lo and Behold, I now have nice, smooth, progressive brakes and no funny noises.
I did check the entire braking system whilst the shoes were off and made sure that:
a) The fulcrum pins were tight in the backplates
b) The cams and their attendant bushes were in good order
as I know from previous experience that defects in these especially can cause all sorts of horrid problems.
As I said at the beginning of this little diatribe, a bit more information would help to diagnose the problem, but I hope my comments help a bit.
