Does anyone know anything about double terrain mountain buggys...I have bought a second hand one off ebay, it didnt say anything about not having brakes but it clearly doesnt have any and Im pretty sure it should! Is that the kind of thing that I can buy a spare part for and fit it myself does anyone know? Or did the old models never have brakes, in which case I will at least feel slightly less 'had'...It has taken a long time to get to me since buying it by way of various friends moving it a bit at a time so basically returning it is not an option. I am really quire disappointed by this!
