rotors are pretty easy, remove the caliper, the rotors are floating so they should pull off, if not there is a couple of small threaded holes on the hat of the rotor, put in a metric bolt to size, pretty sure they're a 10mm headed bolt. Wind the bolt in and it will pop the rotor off if its seized on. Just make sure the mounting surface is clean before you put your new rotor on, or you could have pulsations under braking. Dont forget to spray your rotors with some brake cleaner and wipe them to remove the film they use to protect the rotors from rusting in the box. The slotted rotors are directional too, so check you have them on the right way.
hoses are pretty easy, there will be a U shaped clip holding the line to the strut assembly which you just pull out, then use the correct tool to undo the fittings off the caliper for the hose and off the car. You need a pipe spanner like this.
using this tool will greatly reduce the chance of rounding those soft fittings, unfortunately it happens a lot because people smash on crappy open enders.
Just do them up as tight as you pulled them off and move the steering side to side to make sure its not stressing/twisting the new hose.
Then bleed the system starting from the LHR wheel, then RHR, LHF then the RHF. You Start from the furtherest wheel from the master cyl and work your way to the drivers wheel.
