Had a problem this weekend at the track. I was going into a corner and braking from 90 down to about 30 on a tight corner and the ABS failed to work properly. I locked up the right front and almost went off the track. I flat spotted the right front and ruined the tire. The ABS light and the slip lights came on. When I got back to the paddock and shut everything down there was a noise coming from the area of the brake fluid resevior area. It sounded like a fan or a pump runing. I thought it would stop once it cooled down but never did and I had to disconet the battery to get it to stop. Once I did that the lights on the dash went out and I didn't have any furture issue as I drove home.

Any ideas as to what cause this would be appreciated

 

I had the same thing happen to me with my 04 coupe. But even disconnecting the battery did not fix it, I eventually connected the battery back and disconnected the abs connector and reconnected and it stopped. It hasnt come back even after another autocross event.

 

It happened to me many times, what tires were you using?
