Guys the GQ has three flexible hoses on each axle.
One in the middle, which goes into a t-piece mounted on the axle. From there there is a metal pipe to just inboard of the hubs, and another flex hose on each end, from there to the brake caliper.
There is no point in making the end brake hoses longer, but if the end hoses are in poor condition, it may well be a good idea to replace the center tube at the same time. This is the one which can be made longer if more flex is required.
As everyone has said, any good hydraulics shop can make these up, but quality does vary. I have so far been very happy with Flex-a-hose.
