| Brake plate in 4 jaw chuck |
Being a fan of fully floating rear brakes ,that are a usual feature of my project bikes, I set about doing just that.

| Boring out the brakeplate |
Starting with a turned up spacer and an embiggerated hole in the brake plate all I then needed was a suitable linkage/torquearm and mountage bracket.
Using 2x m12 rod ends,or heim joints as some people call them, and a length of m12 threaded rod covered with a stainless steel tube I soon discovered that it intersected with the swingarm brace.Thus running it under the swingarm was a no go. So i played around a bit only to run it up & over the swingarm instead.Fabbed up a nice pivot from an angle iron offcut then electric glued it to the frame. The arm was going to be powder coated the same color as the frame but as the old hotrodder axiom goes of "if you cant hide it make a feature of it" it's now polished up bright & shiny,loud and proud.

| Rear brake linkage |
The idea is to form a parallelogram which will serve to negate rise or dive under brakes ie separate the braking action from loading up the suspension & thus no skidding or wheel hop when hard on the anchors.
