The best stuff I’ve ever used for brake jobs is the 3M Silicone Paste. I believe that is what GM uses on the assembly line, and what they provide you in little packets when you buy ACDelco replacement pads.
It is ridiculously expensive though. A jar of it will set you back a little over $20 at most retailers.
