I've been having a problem with my parking brake pedal releasing on its own lately. Thankfully, only once was it a problem and I had to jump back into the truck to keep it from rolling away. But anywhere from 30 seconds to several minutes (or more) after setting the brake it will pop back off randomly. I can go for weeks without a problem.

Any adjustments I should look at? Or is it a matter of things wearing and a part needs to be replaced?
