Like Stubby sez, I don't have forward controls... As far as the linkage, do you have drum or disk on the back.?. I've seen them done with an adjustable rod type linkage or with a cable.... the rod type can be set up to pull or push the brake lever depending on where it is hookd up on the forwards...The cable type is pretty much a pull type setup....

And if I don't belong...Who would have guessed it
