Did my wife's 2006 TD4 a few weeks ago and it was no problem whatsoever. All bolts came out ok, I just made sure that I used plenty of copperslip on reassembly.
The handbrake had been playing up for a while and I was a little suspect about it being the cables at fault but with the new cables fitted the difference was immediate and noticeable.
Used Pagid cables, apparently there are some really nasty cheap ones out there without the nylon / teflon coating on the inner (which can increase drag) but the Pagid ones are OE spec and not at all expensive.
You will need a set of ramps to give sufficient access, when doing this type of job I drive the front wheels onto ramps and lift the rear and support on axle-stands. Plenty of room then for my bulk.
