last week I fitted new rear brake drums to the 4A and noticed when adjusting the nearside drum that there was a high spot - drum binding at one point.
On my tour of the Yorkshire dales I noticed that when the brakes were applied there was a pulsing from the nearside rear.
This calmed down a little during the week.
Yesterday I took it apart and found one of the small CS screws that hold the drum in place had its head almost sheared off !!
On the lathe - using the large centre hole to hold it in the chuck - I found that the brake surface was a good 0.016" out of round/offset.
The old Alfins I took off were a lot better at apprx 0.004" off.
Should I expect the drum centre hole to be concentric with the brake surface?
