Here's what I would do: lubricate the sliding parts of the disk brake assembly. This means remove the front wheel, remove the pads. Scrap off any rust or corrosion where the pads contact the caliper. Very lightly grease the edges where they contact, then reassemble. That will probably remove the squeal.

look for stones stuck between calipers and discs??

i'll throw ya a more detailed description ... this is a very light squeal that comes and goes as it feels. this doesnt feel like bearing noise.

standard setup or a swaped in setup ie stanza?. there is also a thing called pad rattle where the pads are loose in the caliper, which causes a harsh vibration which we pickup as a loud squeal that could cause it. its not a wheel bearing noise? (sorry to ask)
also could be a stuck proportioning valve. that is it isnt letting all the fliud return to the master cylinder thus leaving the brakes slightly on

well the squeal is only there when i'm not applying the brakes and goes away with the slightest touch on the pedal. the pads have some fair meat left on them still

what is the condition of the pads? some have a wear indicator, ie squeal when they get low. or could be metal on metal

yea its a disk front end ... no replaced pads recently

have you recently put in new pads? if so did you machine the rotors when you did. also there are vibration dampeners on some pads that look like shims, did you put them back in or throw them out? that could cause it. also if the pads are in crooked

disks? if so try cleaning the disks themselves.

whats some main causes of brake squel when the brakes aren't being applied? im running a non booster master and have bled the lines recently but it didnt change anything
