As far as I know you can't replace the rotors without loosening the tensioning springs on the EPB. Which requires a flat head screw driver to spin the adjuster with. There is an in depth "brake bible" online for the LR3 which also applies to the LR4. You also have to pull a fuse and put the EPB into service mode. Fairly easy steps. Atlantic British also has a video guide on YouTube. I'd knock it out myself if I had a lift. For now I'd rather pay a shop to save the hassle.
