Re: brakes

Hi, I'm just posting this under the same header re. ABS. I just bought my 86
5kcdtq recently, and when the ABS engages it sounds like a metallic grind. I
don't think this is normal, and I'm going to have it checked, but I would
appreciate some second opinions. What does the ABS on the quattro should
feel/sound like. We just had a lot of snow dumped on, and I would like to use
ABS, but I don't want to damage it.
