I finally figured out the trick to getting that small quadrant off. Crawl under there with a long flat tip screwdriver, and you'll see where there is a metal clip that clips around the steel arm on the pedal assembly itself. stick the screw driver under it, and pry it away from the assembly, essentially unlatching the quadrant from the pedal assembly. next, reach up with your finger, and push the other end of clip through the quadrant as far as it can go. Rotate the quadrant counterclockwise, and depress the pedal as far to the floor as it'll go.. the small quadrant will slide right off.
