Beware tinkering! Also if something is wrong with your brakes, stop and sort it out right away.
Having fitted overall longer and longer travel shocks, it changes the interaction between the movement of the swingarm and the brake rod. If you have them adjusted too tightly, at extreme compression, it will tend to apply the brake. I was aware of this happening but had decided I'd wait until I got home to sort it out. Being so pleased about it passing its MOT, I was getting a little over-exuberant and jumped it off a fairly high kerb with a heavy-ish landing. This fully compressed the suspension and applied the rear brake.
It turns out the grip on heidenau trials tyres at 5mph under full compression is greater than both the tensile strength of a 7/16" brake pivot bolt and the swingarm sideplates!
New pivot ordered. New brake rod being fabricated, swingarm hammered flat again with a smiths hammer and a heavy steel block.
