Probably bad ABS sensors - which are surprisingly pricey - over $100 for each of the front wheels. I have an clever way of eliminating this cost, by pulling the ABS control unit and ABS warning light - but I live in Phoenix, where I could drive a hundred years and never need ABS. On Long Island you probably need to make the investment. You might also try cleaning them first. BTW - I agree with all said about PBR Deluxe - can't understand why anyone would use anything else. But the paste on the back will probably solve your problem. The MB paste works well - comes in little ketchup packets for about $3.00.
