Rear brake questions

[m3brad]

I've looked long and hard and my questions remain mostly unanswered. They are the following:
Is a vadcom only necessary to replace the rear brake pads or is it also necessary to replace rotors, brake lines and/or brake fluid? If a vadcom is NOT necessary for the last three items, is it better to have the parking brake engaged, disengaged or does it not matter?

Thanks in advance for your time.

I haven't performed this on my S3 or my wife's Allroad, but I do know the best way to service the back brakes is with VAGCOM in order to put the electric ebrake in service position. I think it is pretty safe to say you can't really do anything to the rear brakes except maybe change out the rear brake lines without putting the rear brakes in the service position. There is a thread on maybe the A4 forums where somebody hooked a battery directly to the brakes somehow and put them in service mode you may want to search the forums for that.

You can change the rotors without putting in service position as the calliper remains attached to the carrier. To change pad or remove calliper the service position is required.

That's the answer I was expecting and looking for.

That's the answer I was expecting and looking for. I'm going BBK from Exelerate Performance and some matching rotors in the rear!!
