Unbolt the entire caliper and hang it out of the way on an old bit of coat hanger wire, not putting any stress on the brake hose. Don't unbolt the lower control arm, just the two steering arm bolts.
Undo the three nuts holding the strut top, remove two of them and leave the outer most nut on by about two threads.
Stick a hydraulic jack handle, breaker bar or whatever between the lower control arm and castor rod and lever down the control arm using your foot.
The steering arm will come away leaving the strut assembly hanging by the nut at the top. Pull the strut clear of the steering arm, lift the strut slightly, undo the final two threads on the top nut and you are done.
Edit, read your lst thread.
Tap out the clip that retains the brakeline in the bracket on the strut. You then need to make a neat cut into the brakeline retaining bracket. Once you are through one side, tap the ends apart so you can slide the brakeline clear of the strut. Be careful not to cut the brakeline. better to use a hacksaw rather than an angle grinder :jamie:
