I am thinking of going to calipers on my trike. I know hydraulic is the way to go..but... I am thinking if I caught a line and it broke in the middle of a race that it would be easier to fix a cable than a hydraulic line... I am curious how well a mechanical set up using a hand brake would work... Lots of turns so I need it to stop the wheel on either side of th differential so I can turn/pivot. Anyone use one?
