Maybe your return spring for the self-adjuster in rear drums is broken. I
had a similar situation happened to me back in my college day, about 10
years ago when I had a 83' Mazda 626, I know it's not an Audi but what you
describe is similar to what I had experience. I don't think you have ABS
since I notice on your signature you say you have a 84' 4000s. You
probably want to get those drums of on the back and check them. There are
usually 3 to 4 springs in each of the drum assembly. In the 85' 5000s
that I used to have which has drums on the rear, there is a small springs
that runs vertically down the middle of the drum assembly, this is the
spring that is connected to the self-adjuster which is a wedge key that go
between the brake shoe assembly. Every time when you press on the brakes
the wedge key would came down between the two shoes and jack them out
further so keep the distance of travel between the drum surface
relatively the same as your shoes wear down. I would reset the adjusters and
replace both of them if one of them is really broken which caused the
problem. The self-adjuster if re-adjust the brakes after you press the
brake pedal the first time after you re-adjust them.
