How much can the 2018 GMC Sierra tow?

As you can see from the table of towing capacity readings above, not all of the trims can pull the same amount - some are as low as 2273kg whereas some go as high as 4091kg.

What does braked towing capacity mean?

When the manufacturer states that a towing capacity is "braked" they are referring to brakes being fitted to the trailer that the car is towing.

At least one of the axles on the trailer that the vehicle is towing must have brakes fitted and controlled by the car if they describe the capacity as "braked".
