Hey my passengers side caliper carrier thread is stripped both top and bottom. Does anyone know what size helicoil I could use to drill this out!? Thanks for the replies in advance, I've been looking everywhere but can't find it.

A4 1.8t quattro,

 

I wouldn't feel safe helicoiling a caliper carrier. Find a used one, they're a dime a dozen.
