The earlier cars had different rear calipers from the later (2004-) cars.
The trouble with these earlier calipers is the hand brake mechanisim can stick/seize and you've guessed it, cause squeaking, hot wheels and the usual brake binding problems.
There's no real, 100% sure fire way of sorting long term, as new calipers will go the same way eventually.
You can fit the later calipers and pads, pick some up used of fleabay, I think many have writen they are just a swap over, so hangers and cables are the same, but it's worth checking.
You can have a go at cleaning/lubing the handbrake ratchet on the inside/rear of each caliper.
There maybe some help on the forum somewhere in the past, so worth a search.
