[200q20v] Fading Brakes when wet What are the Options

[Fred Munro]

Hi Grant;

I've noticed over the past few years that initial brake response is very
poor after driving in winter salty, slushy conditions if I haven't used the
brakes for an hour or so. After leaving the car sit all day after a salty
drive, there is no brake response for 5 seconds after application - it feels
like the pads are greased. Returning response is exponential as the mystery
substance wears off. I suspect whatever it is they are using instead of salt
on the highways - I've only noticed this phenomena in the last 3 years or so
on both my 200q and my S4.
In my case, summer wet weather driving does not cause the response problems
winter salt slush driving does.
