Just installed mine yesterday. 2 bolts to take off the foot board, 1 nut to take off the lever, and 3 bolts to take off the entire bracket the master cylinder is mounted to.
Had more trouble removing the rubber brake lever pad. Wound up using hot soapy water and 2 slim blade screw drivers slipped down each side. The pad has raised portions along the slide that slip tight into position. I used just water to reinstall but I've read window cleaner slicks it up just enough to let it slide back on.
