C5 Rear Axle/spindle Nut Socket Size?

[Guest C5Newbie]

Hello, I am getting ready to replace my rear brake disc and I was wondering if anyone could tell me what socket size is required to remove the axle/spindle nut? 39 or 40mm?

There's no need to remove the central nut to change the discs. Only remove the caliper bolts and the two torx screws.

Thank you for the reply John. I removed the caliper bolts and the torx screws, but the disc will not come off. I will try a few taps with a hammer tonight. Mark.

the disc will not come off.

 

They can be very stubborn - sometimes a bit more than a tap is required. Smear some copper grease on the new one.
