description A body of a shear pin can be positioned in a pad stopper of a steering pad of a rotary steerable system. The rotary steerable system can be used to steer a drill in a wellbore. The steering pad can be positioned on the rotary steerable system such that a head of the shear pin is coupled with a lateral pad of the rotary steerable system. The head of the shear pin can deactivate the steering pad by preventing the steering pad from actuating. A fluid pulse can be output in the wellbore to break the shear pin for enabling the steering pad to actuate to cause the rotary steerable system to steer the drill in the wellbore.
