Make sure the rear bias valve is held open, otherwise the rears won't bleed. I used an eezibleed pressureised kit, super easy but had to keep pumping up the spare tyre, ha ha! I didn't drain it but used the pressure to push out the old fluid, go round the car starting with rear passenger and work towards the front driver (furthest first, closest last), opening each nipple and waiting for new fluid and no bubbles. Keep a close eye on the reservoir while bleeding, DO NOT LET IT GET LOW, you'll put air in the system and at best you'll have to do it again, at worst you'll have no brakes when you want them.
