After I drive the truck for >30 minutes and get the brakes nice and warm, I experience a grinding noise coming from my right rear at idle speeds w/o pressing on the brake pedal. If I just ever so slightly put my foot on the pedal, the noise goes away. The noise doesn't appear until after I've driven for sometime so the dealer is unable to replicate it but it drives me crazy. I have replaced the entire brake rotor/drum and had new pads installed. I think it might be parking brake related because I can push down on the PB while slowly driving at idle in a parking lot to make the noise go away. Could the cable tension on the PB be a culprit? Any help would be greatly appreciated.
