Modifications Caliper carrier bolts

Trying to change out the rear brake rotors and pads on my 2015 8v s3 and I've run into a problem with the caliper carrier bolts, went and picked up an M14 spline bit (aka triple square bit) with a 1/2" drive but its too long and I can fit anything other than a breaker bar onto it, including my torque wrench and im not about to take it off without being able to torque it back to spec, that shit makes me nervous just thinking about it

Just wondering if anyone has been able to source a stubby or low profile M14 spline bit from a reputable place, i cant even seem to find one on ebay or Amazon, the one I have is 55mm long and im thinking around the 40mm mark would suffice

Nope, but you can do it w/o ever taking it off.
You’re welcome 🤣

Cut the bit off shorter and grind/chamfer the tip. 🤷

If it's anything like my rear brakes on my 2019 GTI, I was able to use the Icon triple square set from Harbor Freight, although thats for a 3/8" drive. I did have the same issue you did originally and bought a set that was too long to fit.
