Ruby Mk1 brake shaft removal
To answer the original question.

The only removable part in the assembly pictured is the outer lever. Obviously by removing the cotter and sliding the lever off.

The inner and outer shaft are fixed in the centre by a pin, which is fixed so as not to be removed at factory. I've never felt the need to remove one, but they are either welded or rivetted in. The pin from memory is visible by peering down the inside of the shaft and is located (again from memory) in the bearing surface of the centre bearing.

If you really want to remove, be prepared to do.a lot of remedials to the shafts when you have accomplished your task.

The way the shaft works is you stand on the pedal, via a rod it pulls the inner lever in your picture forward. The outer shaft transfers the torque to the 'centre' of the combined shaft, where it is the  transfered via the inner shaft to the outer levers, and thence by the cables to the rear brake. 

The 'centre' of the combined shaft actuates the fronts.  

The theory is you get equal twist in the inner shaft so the rear brakes come on evenly. It was certainly an improvement over the previous shaft which was simply a cross tube. 

Its a very regular question on here. But simply answered. 

To remove the shaft from the bearings, you will need to remove the lever from the nearside of the shaft. And dissasemble the centre levers and rocking shaft. And take out the spring peg. The whole lot can then be pulled out towards the offside.

You will find wear in both the zinc bushes and the sherical bearings. I fit bespoke bushinge in bronze or nylon. And the sperical bearings can be refurbed by splitting the pressings that hold it, and by deforming the flanges so that the sphere is just nipped when the two halves are tight together. Obviously all needs rekoving from the chassis to do this. Refit with tight fitting HT bolts. When assembled the shaft needs to turn easily, so easily that the spring returns it unaided
Oops for taking so long to respond.
End July 2019 I found myself in ambulance on way to hospital, with Twos & Blues going, the journey normally takes 35-40min, but this time about 20.
Blocked main artery to heart needing a balloon inserted pdq to clear it.
One ‘slight’ problem though, my heart stopped during said procedure, needed cpr and a couple of injections to bring me back.
I will remember the second this happened forever.
When in Recovery Room the specialist who did the procedure told me quite nonchalantly “You died, but it’s quite normal for this procedure’ ?
The bruising left from the cpr meant I couldn’t lie horizontal for nearly 4weeks, sleeping quite happily in my armchair set around 40°.

When I went to see the specialist 2 months later, he showed me the recording of the blockage during the procedure and I asked him “You caught me just in time”
“Yes!” was his reply.

I think the whole episode had a psychological effect on me of some sort as I lost interest in just about everything mechanical, but did turn a section of the back garden into a wildflower meadow beginning 2020.

Only now getting ‘mechanical’ enthusiasm back.
One good thing though is that I am now back to walking nearly 4miles with ease, something I haven’t been able to do for years.
Back on the Ruby this year I hope as last year’s humidity didn’t play well with me?

Geoff - My list of things to do has grown somewhat, so ‘Finger out’ is called for??
Ah that explains the silence and glad to hear you are on the mend Geoff.
I welded a nut on the end of lever and then
Removed lever with.a bolt screwed into
The nut cut nut off when done !
My problem I ask questions that other people don't like?
Like have you got that for an investment or for fun?
