Re: Handbrake and MOT's
I would concur. The duff reading is more likely weak calipers than a badly adjusted handbrake.
Normally with the self-adjusting handbrake mechanisms the technique is to wind the pistons back just enough so that the new pads fit over the disk (they're thicker than the old ones). Then pump the brakes, then adjust the handbrake.
If that doesn't sort it, then you're looking at a caliper strip-down.
If your calipers are weak your rear disks will be slightly grubby, or the outer 1cm will be darker than the rest of the disk (especially the inside face). Compare them to the front ones, which are probably gleaming all over, both sides.
