I had a similar problem with a Sony open reel deck. In that case is was a stainless steel band with the composite which had decayed. I replaced the composite with a strip of leather, in my case taken from a worn out wallet. Works great. I glued the leather to the steel with contact cement.

I tried some silicone rubber sleeving thinking that the hollow structure would give squashiness and the rubber for the friction but it was too thick and grabbing-on/stalling, rather than braking in the forwards rotation sense. Leather sounds a reasonable structural equivalent, will give that a go.

What about felt and then wipe some silicon rubber sealer into the surface ?

I would try the material from a tension band.
