That doesn't sound good at all.
You get used to it, and get in the habit of applying the brake ever so slightly frequently to keep the drum warm and dry.

The drum on the B44 is a massive lump of cast iron, and the wheel weighs more than the single disk G/S front, although I suppose the weight of the caliper must come in to the calculations somewhere.
Works better than the disks on any of my Beemers, but it doesnt have a lot to slow down - the Victor is less than 300lbs with a full tank.

That's amazing since it sounds like the front wheel is 100. :lol:

I think it dates back to around 1938, which makes it almost 73.

They were old stock fitted to the B44 around 15 years after their last appearance on one of the heavyweight twins, and are really overkill on the B44.

Back in 1962 I fitted one to my Sunbeam S8 in place of the puny thing that BSA fitted, and even then it came from a bike to old to be worth repairing.

But those were the days when a worn out Vincent could be bought from a junk yard for less than $20-

If they are set up wrong they are worse than the single disk on the /7, set up right they are the hand of god.

And if you need more, the back brake plate from the rear Morris Mini fits right in , and then you have a hydraulic full floating twin leading shoe monster- Mead and Tomkinson fitted one on their successful B50 endurance racer.

That would certainly make for effective, but it sounds even heavier.
