I have what I think is a rather unique brake noise to deal with. Everytime the speed of my car (an '84 Plymouth Horizon) drops down to around 5mph or less, I get a fairly quiet high-pitched squeaking sound from the left front wheel, sounding pretty much like air leaking slowly from a balloon. What's interesting is that the noise is exactly the same whether or not the brakes are being applied at the time. I followed the factory shop manual's instructions for similar squeaks, which was to clean and grease the caliper adaptor guide rails (what the pads slide on) and re-glue the noise suppression gaskets (which were still sticking fine) behind each pad. This got rid of the noise for about 1 mile, then it returned, sounding exactly the same as before. Rotating the wheel in question produces a very slight dragging noise from the disk, but no more so than for the other front wheel (which doesn't squeak). Also, the caliper remains cool to the touch after a long freeway run, and there's no sign of excessive pad wear or overheating, so I don't think it's dragging very much. It's only been doing this for a few days, but I'm something of a fanatic about unidentified noises from my car and this one's driving me crazy. Does anyone out there know what this is or how to determine it? Will it likely go away on it's own after a while? I hate taking the car to the dealer, but I'm just about ready to try it. Any suggestions, by net or E-mail would be much appreciated. P.S. Further relevant info: Car has 28,000 mi, gets almost all freeway driving (brakes are hardly worn), and the brakes function perfectly otherwise.
