I found the brake pedal a little too far of a reach for my normal foot position so I adjusted it where it sits back about an inch closer to me. Once you remove the plastic side cover you can see the U shaped bracket where the arrow is pointing that the large shiny threaded rod goes through with a cotter pin through it's end. Hold the nut closest to the master cylinder and turn the nut closet to the U shaped bracket. You might measure it first so you can see how much you are moving it. I can't remember which way is back or forward but you will figure it out. Test ride before putting plastic back on. It sure made it easier and more controllable to use the back brake.
