RP Rear brake cables

[Roger]

Tony,
The old lever is badly grooved and the ball oval although it does not show in the photo.
I have spent most of this afternoon with a file and carefully reprofiled the lever, it looks promising.
I hope to have a result sometime tomorrow it is a slow job.
The old one was 0.100” wider at the ball end I have removed the shoulder as well witch is a great improvement.

Oavality of the ball is not a great worry, but necking is bad. I would look for a good second hand set of levers.

Tony,
I have spent today filing the levers to an acceptable profile.    
The result is as below.
On full lock the cable is more or less straight now, just as I expected it to be.
There is still a slight bend showing but that is left over from the previous stress on the cable.
Most of the available levers are identical to mine, I wonder why other people have not had the same problem.
