I was once told by a gm engineer that most brake squeek come from vibrations or movements. Threw alil testing of my own on about 100 customer cars I have found that making sure all contact point that the pads touch pad backing, caliper, slides, or retainers to be properly lubricated. I have found that with a light coat of gm anti seize (making sure not to get on friction or rotor surface) I have never had a vehicle squeak or return to me with a squeak. I have even redone other's brake jobs that squeaked the same way and BBC fixed their problem. Maybe give it a try and see if it helps. GL with ur repairsbhope it helps.
