How do you dismantle the Shimano roller brake?

It doesn't brake as well as it used to, I wondered whether the brake
shoes are worn.

Does it need to be re-greased?

I know this may sound odd, but it does help.

If you remove it from the hub you can prise off the cover. The whole
works comes apart without tools. Not much point in this excercise though
(no spares available, you replace the whole unit), but you will find
there are no brakeshoes. There is a greaseport in the cover though,
closed with a rubber cap. Use Nexus brakegrease.

Last time I had mine done, the LBS used a their standard grease that was
in the gun. I have not had any problems. I suspect that the requirement
to use Shimano's Nexus specific grease is overrated.

I have tried greasing them, though I used the grease that was in the
gun. Sheldon Brown says to put a conventional brake on the front, but
that means replacing a wheel which hasn't died yet.

No shoes? But the website says...

If it moves, take it apart to find out how it works!

Why would the wheel have to be replaced? Isn't the rim suitable for a rim
brake?

The roller brake could be removed or left on the hub.

there are three solid steel segments which are pressed against a drum,
not the usual brakeshoes with a liner to wear

Mrs B has roller brakes on her Ridgeback. I had a spin on it the other
day and noticed one brake (the rear) was particularly poor. Solution was
to take some slack out of the cable - this could be done on the
adjusters but ours had ran out of adjustment so I had to loosen off the
cable clamp and pass a bit more through, while moving the brake
actuating arm round a bit. It writes harder than it was ;-)

Perhaps I should put some grease in as well..

ps a new brake unit is about thirty quid from St John St

No, it's the kind without a brake track. So I can't fit either a rim or
disc brake without replacing the wheel.

Can I have a disc brake on a dyno hub?

Yes, though it would would seem simpler to use the drum/dynamo from SA.
At least that way you don't need to get a disk brake and fork.

this is probably not going to improve the braking over the current setup.
Sram I-brake is another possibility
