I can't speak for this particular vehicle, but most 4x4's like these have disc brakes on the back that are operated by the footbrake, and the handbrake has its own small pair of shoes, with adjusters, incorporated in a drum just behind the disc...so to reveal the drum and shoes, the disc has to be removed. Its worth checking these out first, unless you can see that the handbrake cable has snapped. Cheers John
