David,
I'm not attacking you personally. I'm giving you feedback about your consistent online behavior to NOT accept a contrary opinion, despite what you said above. You keep repeating wrong information when you are challenged. Tell me, is that because you are afraid to say you were mistaken, because you feel you don't have to due to your self appointed moniker, or some other reason?
I'm glad you agree that we are all here to help each other out. That being the case, I'm sure that it isn't your intention to spread incorrect information. So, it's what you choose to do or not do with the feedback that is important.
Finally, please don't tell me to do my research on brake pads, or to accept the self correcting nature of the forum. What audacity! I don't need your advice on these parts and I didn't ask for it. I challenged YOUR incorrect advice, remember? Like you said, this is what makes the forum better. Please listen to your own advice. That is the bottom line.
If you want to discuss it further, send me a PM.
