My rear brake pedal is too low, I have to rotate my foot forward more than I like. Has anyone adjusted or modified the rear brake pedal? Looking at the hardware, there appears to be a second hole in the bracket that attaches the pedal to the shaft, I wonder if this can be used to change the pedal position. I do see the adjustment for the pedal, but there is no room to get a wrench on the hardware. The backing nut looks doable, but the actual adjustable part only has two flat surfaces, making it very difficult to get a tool on.
