Can anyone point me in the direction of website/info that would tell me how to strip down and renovate the rear hub brake fitted to the axel of a tricycle?
Many thanks, Antuny
You said the brake is fitted to the axle. That suggests a band brake. Is it on the axle, itself? A photo of it would be useful. [Update] Okay, I found your photo. That's a band brake. To replace the whole thing, the axle has to be pulled.
I had cause to repair a friend's trike on which the freewheel had failed. It meant removing a wheel and pulling the axle after I had slackened the freewheel and other bits. While I was at it I adjusted the band brake. The reason I did the repair was because two bike shops said they can't do it. I'd never worked on one, before, so I was delving into something that might have gone wrong. I told the friend that if I break it, I won't be responsible for it, and she agreed. So after buying a new freewheel at a LBS, I had it back together in under two hours.
And, of course, I may be completely wrong in my assessment of what you want, but in case I'm not, here's a video of how to repair a hub-mounted band brake, but it's on a bike, not a trike. Same kind of device, though. You may have to remove the axle to remove the band brake. Perhaps I should have made a video of the freewheel and band brake job, because I couldn't find one on how to replace the band brake on a trike axle. I hope you have better luck than I in finding a bike shop that will work on a trike band brake and freewheel if you can't do the job yourself.
