Personally if you are going to get some rear brackets try and get some that mount the caliper at 12 o'clock, not only will you have an easier job bleeding them, but it wont be such a tight stretch on the handbrake cable either.

Also, my brackets are counter sunk, so you dont have to drill the hubs and change the bolt through the shock:





Also note the tight stretch on the handbrake cable with them in the current position.
