so yesterday, was sick of the foot position of the rear brake pedal with my foot angled outward at 45deg. changing the height of the pedal is pretty easy.
remove 2 bolts/nuts holding the whole pedal assembly to the frame.
loosen lock nut on the pedal rod.
remove lower spring.
remove cotter pin and pivot pin for the pedal rod.
spin forward half of adjustment section of pedal rod to raise or lower pedal height.
make sure new pedal rod length doesn't pull the spring to activate the brake light switch in its new position.
reinstall is putting it back in reverse.
now my foot rests comfortably straight on the foot peg and the pedal pad just barely below my toes. much better!
