Thank you for providing the helpful pictures. What you have is a Lippert 5,200 lb axle. For brake assemblies you can use the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA. These are 12" x 2" brake assemblies designed to fit a 5,200 lb axle with a 5 bolt brake mounting flange. If you need mounting hardware you can use the # BRKH12.

For replacement bearings you need the # 25580 and # LM67048. According to Lippert the correct grease seal is the # GS-2250DL. If you want a kit then you can use the Bearing Kit, LM67048/25580 Bearings, 10-36 Seal # BK3-300.

I have attached some installation videos for your reference.
