I'm due for new brake pads on the wife's 2011 V6 (T3). I usually use ecstuning, but they show different size rotors for same year and model. I believe one option is 350MM and then another is 330MMx32MM. First question is; which size does mine use or how do I find out for certain. Also I've seen some brake pad kits include wear sensors, do they have to be replaced as well? Last question is, should I just buy OEM VW/AUDI pads or are there better options? The brakes have the common squeaking issue when backing up in the mornings, and I was hoping new pads would correct this, wondering if that was really the case for anyone else who had similar issues. Thanks in advance for help!
