Yeah, they are adequate for 256X13 on front - I have such set of brakes on my B3

Why this poor brake set was factory installed on B2 GTE ["sport"] and mk2 GTI 8v [weak one

] - because for light and realtively weak engine it's enough

My poor brake set brakes stronger than neigbhbours B3's 256X22MM in front and 245X10MM on rear - because mines are in better condition than he's

And, don't forget, B2 GTE's uk name "sport" is just name, there isn't anything "sporty", just nice engine
About seizure - do u have circle fingers?

In latvia's biggest audi forum there is a couple of topics how to refurbish calipers, and, refurbishment also is good chance to colour them

Of course, there isn't anything complicated, where is the fckin problem?
About master cylinder i didn't know anything, it's a good thing to investigate
