A5 Rear Break Caliper Hanger Bolts - Type?

[DannyBox]

Hi all

I'm looking to replace the front and rear discs and pads for my 2015 Audi A5 with a mechanic friend however I want to be sure we have the correct bits to do the job. He is used to older Audi/VW and has asked what the size and type of the bolt is for the rear caliper hanger bolt. I understand from other threads I'm reading that its ridiculously torqued up.

If anyone can offer assistance it is very much appreciated.

Thanks

Performed this job over the weekend, thought I would let people know how I went on:
Front - hanger bolts are normal hex bolts x2 and the caliper bolts are usual VW/Audi allan key style x2
Rear - hanger bolts are normal hex bolts x2 and so are the caliper bolts all be it a smaller size x2
We did not struggle with the bolts, nothing a mallet and some penetration spray couldn't sort out.
NOTE - For rears you need VCDS to put the rear calipers into maintenance mode.
Hope this helps someone in future
