Z4 Pad/Rotor dealer replacement ??

2007 Z4 3.0i coming up on last free maintenance/service interval next month or two. I read about this here but can't find it now. What is the wear percentage of pads and or rotors that is enough for dealer replacement?? I think I read that pads had to be certain percentage gone and rotors also had to be below xx measurement to qualify for replacement of both. I want to measure my rotors and see where I'm at. What is the rotor minimum thickness - anyone have the specs? If I'm not close enough I'll likely go with aftermarket rotors and low dust pads. Thanks very much for any guidance.

The important part to realize here is the 30-05 has two brake sensors ( drivers front and passenger rear ) the 06-08 has only one sensor ( drivers front)

Here is BMW NA's latest clarification (disclaimer) regarding their lame 4yr/50,000 mile Maintenance Program.
BMW Maint Prog Disclaimer.pdf
No free rotors unless the pads are worn down to minimum thickness (3mm) or less.

The free rotors was the selling point for the Finance guy when I had the 04 3.0i but 2nd go around and with 2 years regular warranty left on the M car I passed getting it this time. While some things got taken care of under the extended maintenance contract, for the most part it really did not pay for itself over the course of the 2 year extension.

Best regards

Both of my 07's had the two sensors - maybe yours is just missing the rear one?

This prompted me to go check my rear brake replacement job. The sensor was not missing , it was taped up in the finder well and was missing the retainer clip. That has now been replaced and the person telling me that there was no sensor has been corrected as well. Thank you for pulling my head out, and correcting me or I would have been running around without a proper install. All I knew was I did not have one connected when I did the brake job. The issues you find when you buy a used car.

Got my front brakes done for free.. didn't qualify for a free rotor.. i figure if i took the rotor off, get it machined for 5 bucks,get it replaced for free

Front brake outter pad 3mm, inner pad 2.8mm

Front rotor @ 20.5, 20.4 is min specs.
