Alright i just replaced all the brake parts on the rear of my truck, even new pads. Since about 4 months ago my brakes squeal like a city bus. Im pretty sure its all of them, and the pads are all basically new. SOmetimes they dont squeal and sometimes they do. And it does it if i press hard enough on the pedal, then if i press harder it stops... Not sure what route to go here any suggestions is helpful. I also just bleed and replaced the fluid.
