i am having trouble with the rear brakes on my seicento. i have fitted the complete uno turbo gear (all new, discs, pads, calipers) but i cannot get the pedal to go hard, front all works fine as it has the punto GT discs and calipers, but the rear for some reason will not go hard, i have now removed the lengthened flexi and fitted a copper pipe but still to no avail, i also cannot get the ratchet to work in the calipers, is there any other ideas?
