In order to add disc brakes to your 2018 Keystone Montana 3811MS you are going to need a disc brake assembly, brake line kit, and electric over hydraulic actuator. Please also keep in mind that you will need a brake controller that is compatible with the electric over hydraulic actuator. If you do not know if your brake controller is compatible with an electric over hydraulic actuator you can find the compatibility chart listed on the product page for the electric over hydraulic actuator which I will attach for you.
In order to recommend the correct disc brake assembly we would need to know your axle capacity, bearing numbers/measurements, bolt pattern, and wheel size. The axle capacity is usually listed on the centerline of the axle. The bearing numbers will be listed on the inner ring of the bearing but if they are not legible then you will want to measure where they sit on the spindle and sit in the hub. I have attached an article on how to measure your bearings or find their part numbers and how to determine your bolt pattern. The other option would be to call the trailer manufacturer with your VIN or provide this to me so I can do the same.
For an electric over hydraulic actuator and brake line kit, I recommend the HydraStar Electric Over Hydraulic Actuator Kit for Disc Brakes part # HBA16-252-82 which comes with a 1,600 psi capable electric over hydraulic actuator, breakaway kit with battery, and a 30' main line with all of the other fittings and crossovers needed to attach to your four braking assemblies.
If the brake controller you have now is not compatible with the above electric over hydraulic actuator (see product page) then I recommend the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 which is our top of the line brake controller. I have attached several review/install videos for you. Please let me know when you get the information needed for the disc brake assembly and I will make sure you get the rest of the components you need to add disc brakes to your trailer.
