Hello guys.
Trying to help a friend save some $.
His 07 Q7 just cam up with the brake pad warning.
Did a little bit of research here at the forum, and the brakes on the Q7 looks very similar to the ones one my Porsche boxster. In fact, I found a tread in one of the forums, saying the brakes on the Q7 are identical to the ones on the Porsche cayenne.
So since I already have all the tools, I will help him out and do the brake job for him.
Before I start, I will appreciate if you could help me with some details, or direct me to a source.

So first, I know the rotors can not be machined. I need to decide if to replace brake pads only, or the rotors as well. so I need to know what is the specs for the front and the rear rotors thickness.
Second, I need to know what are the toque values for the caliper bolts.
Also, is it recommended to replace the caliper bolts (as in the Porsche )? or I can reuse the old ones, if in good shape?

Thanks in advance.

Meir.
