Question about GMC Sierra
If you look on the backside of the rear wheels you will see a rod coming out. This is what applys the hydraulic parking break. Try putting some lube on it and move it back and forth a few times to free it up. I found it easier to remove the wheel and rotor to get in and check everything out.

SOURCE: my parking brake is sticking
Either the switch on the lever is not adjusted or is going bad, or the return spring is weak. You could try spraying the cables where they enter the outer coverings with wd 40 or other spray lube and making sure that the cables are not hanging up as well. (good to do once in a while anyhow as maintenance)
