In order to convert your 2022 Grand Design Momentum 5w toy hauler from drum brakes to disk brakes, it depends on if you have triple 7k axles or tandem 7k axles. For a complete kit for both options, I recommend the following parts:

- HydraStar Disc Brake Kit w/ Actuator for Triple Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K # HSE7K-TR1 (triple axle)
- HydraStar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K # HSE7K-T1 (tandem axle)

The great thing about both of these kits is that it comes with all mounting hardware required and also comes with grease seals, caps, races, and bearings.

If you need a brake controller that is compatible with electric over hydraulic brakes, I recommend the Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles # 90195. The P3 is a proportional control which activates the Momentum's brakes in proportion to your braking action. This allows for the brakes to be applies equally on both the tow vehicle and trailer.
