The Good: Easy to bleed and change pads, OK when new.
The Bad: Don't last long, lever design worst I've seen, for 3 finger? Mediocre power and modulation.
These brakes worked quite well for about six months, but no better than good mechanical disk brakes like Avid BB7. After that I stripped out the 4mm lever housing bolts and the rear master cylinder developed hideous play. The brakes never had good modulation on 160mm rotors and were very on/off on 180mm, and the power was similar to Shimano M445 at best, but only when new.
