Rear brake caliper bracket torque

Anybody know the correct torque for these bolts...I've done it up to 75nm as that what autodoc online were suggesting. But now it seems from other places it may be 30nm and 30degrees...Andbody got a definitive answer on this.
Am hoping that 75nm is tight enough because car is in use. They didn't take much force to crack so they can't be super tight.

you mean about those m10 allen bolts? or the normal m8 13 mm ones?

The rear caliper carrier bolts are 30nm +30°, and the caliper to carrier bolts (13mm) are 35nm.
You'll need a thin 15mm to counter hold the slider pin when torquing the caliper to carrier bolts as the flat spots on the slider pin aren't very wide.

It's the 8mm Allen bolts that hold the caliper carrier to the hub.
Autodoc was showing as 75nm so I did it to that and then came across 30nm + 30degrees and wandered which was correct....saying that 30nm + 30 is not very tight at all...
Not sure what to do now as it's all back together...argh..

I've been "here" before when working on an equivalent SEAT, where SEAT just recommend a torque without an extra angle, but VW for exactly the same parts, recommend a much lower torque and an additional angle.
Not very good for a motoring group that shares lots of bits!
At a guess, I'd think that the final torque in each case is near enough the same - but that is just a guess.

Id just say hammer the bit on before turning or they like to strip. Been there done that
And if you were to replace with non oem bolt look for fine thred/ fine pitch one.

Yes its pretty annoying...I've found on other forums now for the 8mm hex that people are saying 75nm so yes I'm guessing must be similar

Cheers mate, yes I gave it a knock in with the hammer
