Help! Stuck parking brake


What I had happen is that a spring in the parking brake pedal assembly gradually failed. The initial symptom was that when I pulled on the release handle the parking brake "reluctantly" released. The problem was worse in cold weather and once the car interior warmed up, it would release correctly. This made it very hard for the dealer to diagnose since the mechanic never saw the car when it was cold. Eventually it failed completely.
If that is your problem and the car is out of warranty, your best bet is to find a used pedal assembly from a wrecked GLK as the assembly is about $400~500 from MB.
Good luck!
