I've replaced the brakes that weren't in that bad of shape anyways and even replaced one of the rotors as it was under federal regulations. I've even put the brake squeak goop on the back of the pads and it keeps squeaking and squeaking and ahhhhhhhhhhhhhhhh it's driving me insane. Am i missing something here? I don't here any other super duty's squeaking on the road. Please help me figure out this annoying defect.

 

Check these things: Do the calipers move freely on the slide pins? Are the caliper pistons retracting when the braks pedal is released? Jack it up apply the brake have a helper try to rotate the tire/wheel right after you release the pedal. If it doesnt release and allow rotation you have a bad caliper and or a bad flex line to the caliper. lastly you could have junk pads. Did you degrease the rotors before you installed them? Grease will glaze the pads. If so degrease and sand off the glazing on the pads. Knock off the sharp edges on the outer circumference of the pads, round them off but just a little. The sharp edges will cause squeal.
