Squeaking while in motion
This squeaking on my 81 is really starting to get to me and I have NO idea what it oculd possibly be.
- It only happens while in motion and starts around 20mph
- Gets progressively faster as I increase speed
- It can't be a belt or anything because they run all the time and there is no noise while I'm idling.
- It sounds like its coming from the foward left side of my hood but that's as good as a guess.
- It kind of sounds like a bird chirping.
Has anyone had this happen before? I'm out of troubleshooting ideas.

The rotor problem is possible, because as I brake it slowly lets up. How would I adjust this to find out for sure if this is it?
(Side note: My brake light on my dash went on about two weeks ago and I thought this light was only hand brake oriented, but since my hand brake was in working condition i assumed that there was a short in the computer causing the lgith to go on. I later realized that this is for the entire braking system and when I opened my master cylinder my back chamber was almost bone dry. I refilled it, but I noticed that when I was running on low brake fluid there was no squeaking, but as soon as I refilled it came back)

i don't think it has anything to do with the brake light... ok heres a simple test.... on a straight deserted road when the noise happens turn off the engine and listen to see if its making the noise.... if it is we know it has nothing to do with the engine.... then apply the brakes and see it it goes away.... if it does you know you have isolated the problem... be sure you don't turn the key and have the steering wheel lock... not sure on your model how your steering wheel locks. either corvette central or ecklers sells a product to eliminate this squeal i'll see if i can find and get you a part number.
