I have a 2010 Sportwagen tdi 6MT my parking brake was very tight and only working on one side. I live on a steep hill so I need to use the parking brake to hold the car. The other day I wanted warm up he car, I pulled the parking brake up and pressed the clutch did not hold pulled more, boom handle came all the way up and now I have no parking brake. I have a 110v outlet behind center console so access from the ash tray won’t work. What do I need to do to access the cables to repair.
