This morning comming to work .I was going about 70 from 100 to 295 north on the ramp .I was entering the last corner when my front left brake started braking and pulsating on it's own.The slip light had come on .The road looked dry but it was a little foggy.The car sensed slip before i did.It slowed me from 70 to 60.I felt in control so i didn't panic.I kept my speed i didn't take over .The car handle perfectly.
