The rear brakes on the NG900 and hatchback 9-3 are high wear items, especially if subjected to road salt and slush. Our '96 900 just had its THIRD rear brake caliper/rotor/pad replacement in 160K miles.
If it's already metal to metal, then rear brake function is pretty much minimal right now. If you're lucky, replacing pad/rotor should be enough. Ours needed caliper replacement too because they had seized due to the salt used in the upper midwest.
