pimpdriver can u tell me why calipers seize in uk?

Here, in latvia, are bad roads and salt on roads in winters so I presume if calipers on 20 years old audi have some problems, it's ok, it needs to be fixed and that's all. Can u tell me why I can't find "high performance drum brakes - replacement for disc brakes"?

And how do u think, why VAG only paired drums on rear with weakest of all discs on front?

Maybe because VAG used only some weak drums? I have seen drums that can put on brake tester braking force as big as 276mm discs or even more - but this was chevy astrovan with HUGE drums

And there is also visual aspect as well.
