They all squeak and badly...I have tried cleaning and filing the pads, backing off the e-brake, lubing the pins and applying red anti squeal goop to the back of the pads all to no avail...seems some guys are putting a chamfer on the edges of the pads and that seems to help but it seems the only fix (and probably my next step as well) is to go to EBC pads which are a bit softer and seems to stop that retched squealing
