E-brake Does Not Work

Hey I have an issue with my e-brake, in the fact the when pulled nothing happens. The car rolls on the smallest inclines ( I have played with the adjustment nut and no difference). I tried to replacing the drums and shoes (pads) and nothing worked. I have also I took it to a shop to see what was up; they said they saw nothing was wrong. And now I have a clicking sound from warped drums. :o

Help; thanks:
