S-type rear disc removal
Discussion
Decided to replace pads and discs all round on the old girl as she is going to be billeted in France from the 25th for a couple of years until they iron out any teething problems on the XF.
Front discs were a piece of p
s to change - they fell off the hubs after I had removed the pads, caliper and caliper anchor assembly. My all-new front brakes now look pretty and work extremely well.
But
(There's always a "but"
The rears were a complete pig and refused to move off the hubs at all, despite a little gentle persuasion with a nylon-faced mallet. As I was a bit pressed for time and garage space I didnt want to damage the old discs so I aborted the job and put everything back as it was.
The last time I came across recalcitrant brake discs like this was on a Transit van. I had to take the front hubs off and grind away a 15 degree slice of disc (like a pie slice) so I could open up the tatty remains with a cold chisel (like splitting a very thin log) and break the corrosion which was holding old disc to hub. I am prepared to do this on the S-Type but would like to know if anyone else out there has done this job and successfully overcome the problem described without resorting to such extremes! The fact that the rear hub nut has to be tightened to 410 Nm means it will be a sod to remove...

Scrub the hub center with a wire brush, hit it with some penetrating oil, let soak for 5 minutes. Screw a lug nut on partially and beat the livin' bejesus out of the backside of the rotor with a 4 lb. deadblow.
Before installing the new rotor do some more scrubbing with the wire brush and give a light coating of anti-seize to the hub face and center so next time you don't have to go through this....
