Had a very close call this morning, it is freezing cold here in NJ, got into my Koup at 8AM and went to work. Got on the highway driving about 40 MPH and began to brake to slow down for the traffic up ahead..and it would not stop at all..it just kept going [ the road was clear so it was not an ice issue] I then pumped the brakes a few times and I felt the ABS chattering...and still it would not stop. I was not sliding...I just wasn't stopping. My rotors must have had a coat of ice on them. Finally in desperation I swerved into an empty lane and managed to get it to stop. To give a visual, after pumping the brakes I still continued for an additional 20 car lengths. That's a lot. I got off the highway and drove around some local streets to do some slow stop and go driving to let the brakes heat up. Things were fine after that. Warning: do not go to fast on a cold morning unless your brakes have warmed up a bit because you might not have the 'stop on a dime' power like you would expect.
