Thought I would resurrect this thread since I'm having similar problems but the repair doesn't look to be exactly the same...
On my 2003 S430, the parking brake release handle sticks out of the dash about 2"-3". It's clear that it doesn't connect to anything, and upon close inspection of the parking brake mechanism itself, there are related issues, I believe.
The detent (#25
) is clearly broken on my parking brake, which prevents it from latching should you push it down with your foot. If you attempt to do this, it just returns to the released position.
I have to believe that the release cable must connect to the detent somehow in order to release the parking brake when the release handle is pulled. That being said, there is no sign of the end of the release cable when I look at the parking brake assembly on my car. I can only suspect that it's up in there somewhere, despite no sign of it, even when I push the release handle in all the way.
I would add that I have confirmed that the release cable is properly connected to the handle, too.
What's troubling is that this detent appears to be a weak spot in the design, as it's clearly plastic and not terribly substantial from the looks of the remains of mine. That and the online EPCs suggest that the part is NLA (no longer available.)
I'll be checking with my dealer parts guy on Monday to find out if this is the case, and will report back here.
Meantime, if anyone has ventured into this area and had success with replacing the detent and connecting the release cable I would be most appreciative if you share your experience....
