Speed is not the primary concern with brakes, it is heat that you need to worry about. Just going 80mph and stepping on the brakes should be no problem for the stock brakes. If you did something to get them hot (riding the pedal, repeated hard stops) they will be equally weak at any speed until they cool down to regular operating temperature. Higher speeds will obviously heat brakes up faster, so there is some speed at which the stock brakes will no longer be effective, but they should have no problem with 80mph during regular driving. I think you need to give us more information about the circumstances and what happened. Were you using the brakes a lot before this happened? Were you running summer tires in cold weather? Did the ABS activate?
