Hi Jack, thank you for your response. I just measured the length of screw threads currently showing including the ones covered by the JAMNUT. There are currently 7/16" of an inch of screw threads showing including the ones the JAMNUT are riding on. If I understand what you said in your response, after loosening the JAMNUT, the number of visible screw threads should be increasing when I turn the ADJUSTER the correct way (clockwise?) away from the JAMNUT. From what I am experiencing, I guess the ADJUSTER mechanism has not completely loosened up because the number of screw threads are remaining the same with the entire ADJUSTER mechanism turning. Ahead of the JAMNUT and below the ADJUSTER, there are silver metal round spacers that are each approx. 1/2" inch long that turn independent of the ADJUSTER. I am thinking that when I turn the ADJUSTER, these 1/2" inch long spacers are also turning which does not allow the ADJUSTER to turn independently increasing the number of visible screw threads. In turn, I am thinking I am going to have hold one of these spacers with a pair of pliers while turning the ADJUSTER which should then prevent the entire ADJUSTER/SPACERS mechanism from turning. Then, when I turn the ADJUSTER, it should be the only thing turning which should increase number of the screw threads properly adjusting the Parking Brake mechanism. Please let me know if aforementioned makes sense. Thanks, Allen.
