Art. 7.07. SURETY MAY EXONERATE HIMSELF.  A surety upon any such bond may, at any time before a breach thereof, exonerate himself from the obligations of the same by delivering to any magistrate of the county where such bond was taken, the person of the defendant;  and such magistrate shall in that case again require of the defendant bond, with other security in the same amount as the first bond;  and the same proceeding shall be had as in the first instance, but the one year's time shall commence to run from the date of the first order.
