I was having problems with my back brake grabbing enough. I would push HARD on the pedal, and wouldn't get much stopping power. I lubed the pivot bolt on the foot pedal...... now it works 100% better.
I think I'll try that first. Take it apart and clean/lube. See how it behaves. I was thinking of rebuilding my spare one, and swapping, and see how it behaves.
Adjusting the push rod will bring up the pedal a bit. But not much, so I purchased a chrome pedal cover from show chrome I believe. This addition has it just right and I removed the entire arm and added a bit more of a bend in it to bring the pedal out further. The pivot should be lubed every year as well.
I still have my GW floorboards heel/toe shifter, which has an addition for the brake peddle. I'll look at trying that 2nd.
It's not that it doesn't move, or make the bike stop. Was just thinking of stopping in an emergency, wanting more force on that rear tire.
