I feel like I'm posting too much on here, but I couldn't find my answer through search. The previous owner on my car said he never used the parking brake, and it wasn't working. I checked all the lines and the internals on the lever, and it seems to all be there, and it does seem to kinda work if I pull really hard on it... but it only goes a couple clicks. I can feel some resistance if I turn the wheel by hand, but not enough to hold it. I searched on here and found a couple posts about cleaning/regreasing where the lever attaches to the lines so I did that. No difference. When the lever was unattached it moved through all the clicks, so I know that's not the problem.
I do remember the previous owner talking about just needing a clip to make it work but I didn't ask him more about it and don't know what that is. I seem to have all the same parts that the service manual has shown though. Any suggestions? Am I actually missing something here?
