Looking for Brake Assembly Set that Fits 2019 Grand Design Momentum 381m
Updated 05/01/2026 | Published 04/29/2026 >
Question:
I have a 2019 Grand Design Momentum 381m. It is supposed to have 7k axles. Does anyone know if these brakes AKEBRK-7-SA are the ones that fit it?

Hey Wade, since we know your 2019 Grand Design Momentum 381m has 7k axles the correct brake assembly set you'd need would be the part # AKEBRK-7-SA and you'd be set with self adjusting assemblies. How does the drum of your hubs look?

I replaced the brake assembly 2 years ago on 7k lb. axles on my 2019 Heartland Bighorn 3970RD, did the work myself and traveled all around the US with no problems.
