This is kinda one of those " to each his own " type things. You know, personal preference. The band brake gets a lot of unnecessary crap (like Birdfinatic ) ..... It does its job, as intended. I can stomp on my brake, and from 40+ mph, I have NO problems stopping. AND my band really needs to be replaced. So I know, first hand, that they are quite effective at scrubbing off speed and stopping.
The mechanical disk brakes is a good cheap option too, so don't get me wrong. They are very good at stopping bigger karts, and will lock up the rear tires on a smaller kart.
Are you not stopping like you want? Can you post a pic or 2 of your set up? Maybe you just need some tweaking to get the stopping power back.....
