Squealing brakes, with a twist
My fiancée has a 2006 Commander, 2WD, that has developed squeaking brakes. Initially it did it only when rolling out of the driveway on cold mornings, not it does it any time the brakes are applied and it seems to be coming from all four wheels, although not all four at once. Beyond that it seems rather random, not all wheels do it, cornering makes no difference in volume or intensity. There is no difference in "Feel" through the pedal when it squeaks. This Commander pulled a trailer loaded to about 6,500 pounds from Kentucky to Montana in August 2011. At no point did the brakes get overheated, in spite of the load, to the point of fading or acting strange. In June of 2012 it pulled the same trailer, loaded to 4500 pounds from Montana to Oregon. The rotors and pads were replaced by a shop in Kentucky weeks prior to leaving, and the vehicle has less than 6,000 miles (Including the two moves) since replacement. I have no idea what parts were used.
Now for the odd part. I removed both front tires and pulled the calipers and rotors. The pads seemed pretty glazed so I scuffed them up with sandpaper. The rotors seem good, no odd wear patterns, no grooves or ridges. I found no debris, other than brake dust anywhere. When I pulled the brakes apart I cleaned the thoroughly with spray brake cleaner and a wire brush, I lubed the bearing points on the pads and applied CRC Disc Brake Quiet to the backside of the pads. Upon reassembling the brakes and test driving the squeal is markedly worse. The brakes still seem to work properly, but my fiancée is still pretty worried and I am at a loss. The noise sounds for all the world like wear indicators dragging on the rotors when braking, but these pads have no wear indicators.
Does anyone have some wisdom beyond just replacing parts that appear to be otherwise serviceable?
