I think mine failed on the same issue, (now resolved). I did not replace the valve though, IIRC it's quite an expensive part. Instead I replaced the rear discs and pads, and had the calipers reconditioned -a worn or leaking caliper would also cause an imbalance. I'd also suggest replacing the two rear (half) hand brake cables -they are quite cheap and should improve the hand brake berformance, which is notoriously bad on the FTO.
