Had a similar problem with my s1, but not as pad, just to much travel in the predal before it started to brake, was told a master cylinder with a bigger core was needed.
Firstly, the bleed nipples on the front callipers point directly up 12 o'clock position, not with the rears however as this was totally impossible due to how far the handbrake cable will stretch and the limitation of the brackets only allow 2 different mounting positions. The calipers as you look at the wheel are between the 10/11 o'clock position, meaning the bleed nipples point out towards the rear of the car at a 3 o'clock position.
The nut on the master cylinder makes sense, but im sure however that it feels like air as the pedal has no hardness in it at all, but wouldn't go a miss, i've got nothing to lose by trying it
Is that however what the nut is intended for, or a bit of cheat if you get me?
As for the master cylinder as matts1 suggested, ive changed it for a mk4 90 spec cylinder, the mk3, and mk4 pre 90 specs have a 22mm master cylinder, mk4 90 specs have a 23mm, which is what ive fitted, and also changed aswell for one i know was definately 100%.
Just out of interest what was the solution to yours then, did you change the master cylinder, and if so what for?
Any other suggestions? I'm still yet to try re-bleeding the rear calipers dropped down, i was in some doubt when i bled them as there was still a couple of tiny tiny air bubbles. thanks for your suggestions however and i'll definately bear them in mind
