Why “stitch” a cracked veneer?
First the determination of the cause of the crack is important. Assuming the cracking is a typical stair step opening originating at the corner of a window or door, the crack will most likely be associated with rusting lintels. The volume of rust created by the oxidation of the steel is greater than the original steel thickness. Much similar to an ice crystal that dislodges objects due to the volume of ice created. Cracking such as this creates a discontinuity of the veneer and allows excessive moisture to the cavity while possibly creating a structural issue with the brick veneer. Caulking will seal the crack; however, the monolithic nature of the veneer is still compromised. A Stitch-Tie repair technique is available that can re-connect the disjointed veneer.
