Ouch - I barely mentioned the CD Manuals [even acknowledged it's frowned upon by moderators] and it got the chop!
Anyway,
Front - only trick to the front apart from TLC for sensor removal, is that 15mm M/bolt us used [many metric socket & spanner sets don't include 12mm & 15mm].
Rear - same story for sensor - a little TLC and you've saved yourself 10/15GBP. However a 5 Degree flat 13mm ratchet ring spanner would be handy as its a bit congested with metal on and around the rear callipers. Just, put the handbrake when releasing the one torx screw retaining the Disc/Rotor. then drop it to remove it - a bang with a rubber mallet might be needed to break and cold oxidation weld between the Hub & Disc. Callipers may need rocking to open them up to get the pads over the lip that forms on the outer edge - shove a bit of timber between the pads to keep them apart.
I regularly drop the back discs off to empty the dust that tends to build up in the drum.
NB: I've seen some posts that call for the rear discs to be replaced when they're at 19mm - the discs I have has a min of 16.4 stamped on them, but they are ventilated so maybe the solids are different.
