Im between a rock and a hard place .. Basically the guy at the MOT station ( riverside in Melks) say's the handbrake system need's "re-engineering" But the guy i bought the Trike from say's the bloke that built the trike about 7yrs ago knows what he's doing and up until last Aug 2010 it's worked fine .. i tried to repair the cable ( re-solder t he nipple ) but it keeps snapping ?!?!? "HELP"
