Default Brake Pad Questions - 6mm left??

Audi Dealership had a Service special day with free inspection. So took my car there and they checked everything including the codes and everything came clean. (I was happy!!)

They marked the brakes at 6mm left.. What does that mean?? I know my front brakes were changed at about 35K and the rear were changed at 43K.
So how long the OEM brakes are supposed to last??
Any Experiences ??? I am currently at 82K miles.

Default Squeal like a pig!!! Oink Oink :) Or grind .... Is Min spec 5 mm? >

My indicator light came on at about 85 K miles and i am thinking they were the originals ... still had alot of pad left but i changed them anyway ..... but since i am NOT a fat wallet guy .... more like a sqweeky tight wallet ... i did not replace with the high dollar pads ... i used the el cheepo aftermarket indicatorless ... didn't even replace the rears yet as they looked good.

Default Squeal, grind, both good descriptors. Unless deaf, you'll know when the pad's backing plate...

contacts the unworn annular rings of the rotor! IMO, the active wear sensors are inadequate and just a nuisance. I always cut them off and short out the wires at the pad connector at first opportunity . These active wear sensors only sense wear on 2 of 8 pads, whereas the passive sensors announce a wear limit for any one of all 8 pads. Another reason why worn rotors are superior to new!

Pads only or Rotors too??? I have heard that I have to change Rotors everytime I change pads...???
What pads did you use and where did you buy from???

Default Normally I'd agree that one would be deaf to not hear the grind; however, my recent experience

that led to this level of pad wear-out tells me that's not always the case - I never heard nor felt anything (and I'm pretty aware of these things). In tis case I was into the backing plate a bit definitely got my money's worth out of those pads.
