I'm told it is how the parking brake adjusts itself when the pads get 
worn.  The parking brake lever pulls a cable which actuates the rear 
brake calipers.  Discovered the special tool after battling the rear 
brakes on my wife's Jetta.  I borrowed the special tool from the local 
O'Reilly or Pep Boys.

If I remember correctly, I had to use the brakes a couple times before 
the parking brake worked again.
