Managed to remove the nearside hub nut by the brakes on and long breaker bar method. The offside one was extremely difficult, breaker bar and scaffolding pole and sledge hammer.

I never managed to loosen that FOS hub nut so haven’t yet accessed those brake back plate securing screws. However, although it was a few years ago, I’m reasonably sure that those screws on the FNS back plate were round head with hex socket.
I’m preparing to have a go at the FOS again when I give the front brakes calipers/pads their annual clean & lubricate. To this end I took the car to my friendly local tyre fitter who has a powerful impact wrench to ask him to loosen that FT hub nut. His “Makita” made short work of that nut. It took him longer to stop what he was doing and walk to my car than it did to loosen the nut, which I torqued up again to drive home. I haven’t got the hub off yet, but a close examination of the back plate securing bolts on that side seems to confirm that they are normal hex head flange screws. I hope to start the job tomorrow, weather permitting.
Just for the record, I completely agree with Dave’s suggestions re cleaning out the ABS sensor hole and lubricating it. When I had to replace the defective FOS sensor I had to destroy it to get it out. I did as Dave has suggested when fitting the replacement.
