Front and Rear Brake Component Torque Specs for B8 A4

[AdrianLee]

I was wondering if anyone can give me the torque specs for the Carrier to hub bolts and the caliper to carrier bolts for both front and rear. Also, if you can find the 4 12 point spline bolts connecting the 2 halves of the caliper would be much appreciated, am going to get them powder coated. The only torques I have found on here are the carrier to hub bolts which are 140 ft/lbs but I wanted to verify. Please let me know what you can. Thanks

I finally got the dealership to give me the torque specs, so for anyone doing their brakes here are all the torque specs needed. Hope this helps everyone

These bolts aren't stretch bolts, right? Meaning it was fine to be reused?

[Allowencer]

Any bolt that states: 'x' torque setting + a degree of turn is a TTY (torque to yield) bolt. Those should not be reused. All others are bolted to a clamping load and that's it.

Yielding means to stretch the threads over spec to prevent them from backing out. By distorting the threads, once the clamping load is removed, they should not be reused as yielding them again will not supply the same amount of yield.
