What can I do to solve a squeal that occurs from my front brakes as I am driving. The brakes were put on in the fall, so they are in good shape. The noise goes away as soon as I tap my brakes but reoccurs soon after. The truck is a 1990 F250 4X4.
From what I hear, the squeal is caused by vibration of the brake pad. Repair shops recommend putting on brake shims that you can buy from your local parts place. I've had good luck with an adhesive they also sell. Both of these items keep the pad from vibrating and stop the squeal.
Besides the normal shims or adhesives that belong on the brakes pads, I like to apply silicone or synthetic brake grease to the areas where the caliper slides in the knuckle as well as where the inboard pad rides in the knuckle, in other words where ever there is metal to metal contact of some form.And don't forget the anti-rattle clip on the bottom of the inboard pad,it may be broken or missing!

I too have the very same brake noise as I am driving. I have a 96 F-150, 300 w/auto. I have had two different Ford garages look at it and they both have told me that it is normal metalic brake shoe noises. If anyone has found a remedy for this please let us know. I probably isn't doing any damage, but it is very annoying.
I will have to check into shims, and/or lubes, the rattle clips are in place. I also wonder if the quality of the pads make a difference. I enjoy seeing people catch a glimpse of my truck, but not when its squels so bad.
Concerning the quality of the pads, yes it does make a difference! I recommend the EIS brand,in the "QMX" line.They have painted backings,chamfered leading & trailing edges,come with a lifetime wear warranty, and are also garrantied to be QUIET.

The squeal on brakes is caused by the allumin piston rubbing on the metal backing of the inner pad, noise is not plesant to hear and can be fixed by using a good quality pad, Eis and Wagner make good pads, but they also make a generic pad. Good pads will cost you around $50.00 or more. They normally come painted, and have the shims with them, though not all pads have the shims, installing them and adding anti squeal cream, this will stop the noise. If you current pads are very good still, just install the shims till you need to replace. Good luck
My 1995 Ford Bronco 4X4 has a loud chirping noise coming from the front wheel area when my vehicle is moving. The chirping is annoying. Just had my radial arm bushings replaced and my hubs lubricated and repacked. Could this noise be my brake wear warning indicators --- or could it be something more serious like a wheel bearing, universal joint etc. My ABS light is on which leads me to believe that I need a front brake job. Please advise?

Was your ABS light on before the front-end work? They may have knocked a sensor loose if it has 4 wheel antilock. I would look at the pads to see how much pad is left, usually if there is less than 1/8 inch left, it is time to replace. One way to chack to see if it is brake related is to apply slight pressure to the brake pedal as you are driving to see if there is any difference. Usually the ABS light doesn't come on unless there is a problem with the ABS system, so worn pads shouldn't turn it on. I'm not sure if low fluid would though. Check it, and if it is low and you have no leaks, you may need that brake job, you have worn pads.
I also read somewhere in these pages about the rear sensor getting a few metal shavings from inside the rearend getting on the tip, since it is magnetic, and causing and ABS light to come on. Just unbolt it and pull it out of the housing to check it. Your best bet though to avoid guesswork would be to use a scanner to actually read the trouble code setting it on.
