i did a TON of searching for brake cables longer than 60" for my snowco trike and came up empty handed. I finally went to a bicycle shop and had them order "tandem length" brake cables with an end for mountain bike levers. i also picked up a set of mtn bike levers while i was there (nicer than any of the mini bike stuff i could find). the brand on the cables was "Bontrager" any shop dealing in Trek, or Garry Fischer bikes should be able to get them. also any good bike shop should be able to cut cable housing to any length you need
