Audi 100 Rear Brake Carrier Question

[Jules]

Hi,

Doing an R&R on my Audi 100's (not quatro) rear brakes. Can someone
let me know what size Torx bit I need to remove the brake carrier? The
caliper is off and pads out, just need to remove the carrier for a
good cleanup and in order to replace the brake rotor.

Thanks in advance for any help

peace
