FanFaron,
When I first purchased my 2003 Civic Hybrid in Jan 2007, I noticed a strange noise with my brakes at times. I live near Philadelphia, PA and in January it is cold, often times with snow on the ground.
An odd sound, something like "ping, ping, ping, ping" occured when I braked in snowy conditions, the brakes locked up, but the wheel kept moving forward. This sound also happened when I had a similiar instance in the rain in April.
This brakes of these cars do not liked being locked up while the wheel continues to move forward. To this date, my car has had fine braking performance with exceptional gas mileage, so I can say that at times my brakes have made an odd noise but it has not done anything bad to it as a result.
Hope this helps
