i have an 2001 6spd with disk brakes all around. the brakes were squealing in the back so i replaced pads, rotors and caliper on the rear drivers side. i still have the squealing only when i back up after having used the parking break. i think its because the parking brake isn't fully disengaging. I took apart the breaks and everything looks good with the parking brake and the cable. any suggestions what could be making my truck squeal so bad. also u joints are good so i know its not those... thanks

Did you check the rear brake shoes? Hold on, yes, it does have shoes, inside the rotor, used only for the parking brake. You mentioned everything else, which is why I ask. If you pull the rotor off you will see them.

yea forgot to mention i did that and it all looks good... shoes are good and the rotor is brand new...

typically its a siezing cable, easily checked, remove disc, apply park brakes, release park brakes and verify that they released fully

I agree with Nick. That would be something I'd look at in the course of troubleshooting. A quick way to do this would be to engage the parking brake, then release it and look along the frame, where the cables go into the conduit, and see if one or both are not going back to "rest" position. You should be able tell be the dirt line on the exposed cable.
Then you have to disconnect the cable at both ends and see if it moves freely. Lube may be possible, but I doubt it's likely to help since the cables are plastic coated from the factory to prevent corrosion and allow them to slide more easily. Cables are usually difficult to lube without a special tool, and even then sometimes it won't work.
If the cable moves freely you need to operate the actual brake shoes to see if they are binding for some reason. This can be complicated, as they may not bind with the rotor off of the truck, which may point to a problem with the rotor surface and how the shoes mate to it.
