Hey Mike,
I believe that you are thinking of the bumper for the clutch pedal. The brake pedal lever does not take a bumper. I bumper on the brake pedal lever could very well cause the the master cylinder to malfunction. (I am sure that you already know this.

)
OOPS, you're right Carl, got my pedals confused, but I still say you can't adjust the brake pedal without the cab in place...
