Seems the cable adjustment would only help if your pulling your E-brake handle to it's limit and the brake won't hold. If you still have room to pull then no further adjustment is needed, just use two hands and PULL. I have to pull mine up good and tight and wait to see if the car rolls. My driveway is slopped and this is routine when pulling out of the garage to warm up and annoy the neighbors for a few minutes. I didn't know that it would hold better forward than back, but as RoknDad said keep it in gear as well.
