My parking brake handles is rattling really bad. Could be the Flowmasters but its got to go. It used to rattle before the flowmaster though usually under heavy load. But now it pretty constant. SO I need to come up with a way to eliminate it.

Anybody else have this problem? Any Ideas?

 

I had it on my V6. Drove me insane. I almost bought the leather cover for it, when I realized that it simply goes on top of the brake handle and does not fix the problem. Well, at that point I simply carefully pried off the top side of the parking brake and put it back. Rattle went away. It appears that in my particular case the top cover simply wasn't fully/correctly snapped in place at the factory. Could be the same in your case.
