03 Sedan Automatic. The parking brake has stopped clicking and does not engage, it just pops back up. It was working intermittently, but I think its stopped working completely now. Is there something I can adjust?

Anyone else have a problem like this? I didn't use the parking brake that often before so I don't see how the brakes could be worn.

 

You have to push it alll the way down. Or you're looking at a parking brake replacement

 

When the parking brake was working, I did not have to push it all the way down before it started clicking. What all would a parking brake replacement entail? Anybody have this issue?
