Audi A3/S3 brake problem - Colin M
HJ
I have recently bought an Audi S3 and recently had a fright when after driving on medium wet roads, the brakes failed to work at the next junction. I know to operate the brake (left footed if necessary) to clear the discs after a flood, but the latest models of A3 and S3 seem to suffer from the discs collecting water worse than any of the cars I have driven in the last 10 years. My Audi dealer also admitted an "issue" with the chemical used to deice the roads causing contamination of the discs and brake fade until the coating had rubbed through, but this is a serious issue that Audi claim is common with "open disc" cars (whatever that means). There are numerous discussions about this topic on the Audi newsgroups and forums.
Any comments?

Dear Colin.

We've had this before with A4s and Passats. There is a modified back plate which dealers can fit to help prevent spray reaching the front discs, but this can result in overheating of the front brakes which is why it is not fitted as standard.
