Rear Caliper Mounting Spline Bit?

[paulomarto]

Hi everyone I am going to be replacing the mother-in-laws rear disks, however I was wondering what size spline bit I would need to remove the rear caliper mounting bracket as my local parts shop will have to order it in for me and do not want to be ordering one of each size. I know it is somewhere between M14 and M18 but would rather order the one bit so need the right size.

Any help would be appreciated!!!:confused:

You don't need to remove the caliper mount bracket/carrier to change the discs see this thread http://www.vwaudiforum.co.uk/forum/showthread.php?120039-A3-1.6-Rear-Discs-Possible-To-Remove-Without-Removing-Caliper
