Not too bad a job Dave,set aside half a day. You'll need a mate for bleeding and some amount of air will be in the lines after draining fluid. Subaru lines are handy to change but be careful not to touch any painted areas with fluid on your hands.
Piss easy job Dave if you wanted to give it a go. I'd talk you through it over the phone if needs be. Garage having a lift should do it in couple of hours.
