Thank you for your comments and advice, Chris. I am aware that there is a small amount of ‘rock’ in all of the cam bushes, and I have already made sure that the pivots are nice and tight. I also put a smear of copper slip onto the pivots and the faces of the cams. The drums look to be in reasonable condition, but as they are the earlier type, which I believe were spun, I am not sure if they are still square and true. I have been told that spun drums tend to try and revert back to being a flat plate over time. Indeed, I am given to understand that this problem afflicted the brakes on early 3 litre Bentleys.
