How do you repair the emergency brake on a 1985 VW Jetta?

first thing to do is disconnect the cable between the seats--there are two 10mm nuts on each cable---then climb under the car and disconnect from the rear brakes if drum brakes take off the drumm and you will see the cable--pull back on the sping on the cable,,i lock it with a small pair of vice grips--undo it from the armature and pull it through the backing plate--then pull the cable out of the boby of the car install in reverse---put the cable on the brakes before adjusting the tension in the car good luck
