installing a rear drum brake
 

Even though I have 3 tandems none have a rear drum brake. I would like to install one on my '72 paramount tandem it has a campy 36 hole freewheel hub. I thought it prudent to ask the experts here before I spend the cash for a brake that may not be compatible or may not be able to be used at all. Thanks for your input in advance. I do live in the CO mountains and need more brakes than the calipers on the bike.

That tells me that I don't have the correct hub to add a drum brake or a disk either. so I guess that I will continue tuning the cantilevers for max effort.

We don't have a drag brake either. I've wondered about strapping one of these on my Stoker on hilly rides. We'd need two new commands: 'deploy (drogue)' and 'stow (drogue)'.

Some nice new Campy freewheel tandem hubs on the auction site. Threaded for drag brake. Some of the tandem vendors have new ones also.

Some new compressionless brake housing and some well adjusted fresh salmon brake pads can add a surprising amount of stopping power on clean rims. 409 and a Scotchbrite pad takes off lots of glaze.

If the hub isn’t threaded on the off-drive side, you do not have the requisite hub to thread on a rear drum brake. Years back, the brake used would often be an Arai, they were readily available, were pretty cheap, and are pretty easy to set up but you do need that threaded hub to mount. If your frame doesn’t have a tab for the brake arm, you will have to use a band to go around chain stay (think coaster brake).

...threaded hubs aren’t too hard to find, here are a Phil Wood and a Specialized from a couple of my tandems...note I don’t use a drum, never found a need even when loaded touring in mountains.

This could have been in C&V but since it was tandem specific I asked it here. When this was the built the cantilevers on it were the best of the best. I guess I will pass for now and see if I get the desire to spend more than the bike is worth for a hub and brake. Not much income for these old retired folks.
