I would start looking for an obstruction in the low pressure return lines from rear of the car - to have so many leaks suggests that fluid is not able to return readily to its reservoir.
The oil back harness as Citroën call it, is becoming very fragile - especially on cars that have been "flushed" with 25% diesel in the fluid. Be careful with the connectors around your reservoir - the hoses have been touched up as evidenced by extra clamps here and there.
It would probably help to join the CCCNSW, if only so you can see Bruce in Hornsby and get the spheres tested free (it's relative, and they need to be off the car).
Sphere code ?
