Sorry, "In Situ" is Latin for in place or as it is. I dealt with too many civil and mechanical engineers over the years. I remember asking the same question in the early 70s. Should be safe to ride, if your rotor is warped, the brake will not work at peak efficiency and the pads will wear a bit faster. You have the best time of the year to shop for one , if needed. The prices will increase come Spring.
