Raleigh/Carlton Grand Prix: Adapting rear brake for Jagwire stainless cables/outers.

I adapted the nylon ferrules in the top of the brake levers to fit the Jagwire ones in the same way as the front brakes, by boring out the centre-hole. This is better explained in this post: https://panabloga.blogspot.com/2018/04/raleighcarlton-grand-prix-adapting.html

The bracket on the rear forks that holds the outer and steel-ferrule has a tiny 4mm hole in it, which I carefully bored out to 4.5mm, 5mm and finally 5.8mm. This doesn't leave a lot of metal either side, maybe 1.5mm, but at least it is steel.

I caked the bracket in black paint, particularly in the freshly drilled hole. The 5.5mm diameter alloy Jagwire ferrule was slightly loose in the bracket, but tension from the outer cable holds it in place. I put a blob of black paint on the ferrule and slotted it into place before it had all dried, hopefully giving it an extra fix and minimising the alloy reacting with the steel.

The gold braided stainless-steel Jagwire outers look well retro on the '79 Grand Prix and won't bleed rust from the ends.
