After the Audi 80 handbrake, but where?

Hello all, I have an old Audi 80 2.0E B3 with 113 hp. It also has rear disc brakes and they are relatively new. In the search I have seen that almost all have exactly the opposite problem with the hand brake, but it is like this: The hand brake starts after 2 steps and that so strong that the wheels stand! May be quite cool in winter, but the problem is that they do not solve 100%, especially when the brakes are warm, probably because the hand brake In my Audi book it says that there is a mechanism where the linkage of the hand brake lever and the two ropes converge. That’s exactly what I’m looking for! And find’s net. Some cars can be set at the hand brake lever, but not here, or did I miss something? Is the mechanism perhaps under the heat shields from the exhaust? Because whether they still go off reasonably, screws are completely rotted. Thanks for your help. Manu
