I can't make my car reproduce this, but it happens once in a great while. I'm on the brakes, usually its soft on the brakes, and usually on rougher pavement. I'm braking and suddenly for a split second the brakes aren't brakeing and the car glides/surges forward. Its a weird feeling, then the brakes apply again and work fine.
My fear is that its the ABS engaging when it shouldn't, like its sensing traction loss when there isn't, and that one day its going to do this when it shouldn't be and I'm going to run into someone. I could also just be weird :p
Anyone else experience this?
