Greetings all. I have a 2003 LS with 154k miles. The parking brake currently works perfectly and due to its complex nature, I want to keep it that way for as long as possible. So my question to you all is what preventative maintenance efforts can a driveway mechanic perform in order to keep it working properly. Is there any cleaning, lubrication, etc. that I should be doing on a regular basis? I realize I don't have much control of the electrical modules, etc. but the mechanicals seems like something I can apply some effort to. Your thoughts?
