Question:
We have a 2022 Grand design Momentum 350G, build date of July 2021, 7,000 axles with self adjusting brakes. It has 8 bolt wheels and 17.5 wheels. The online listings dont seem to address these. Can you suggest brakes with anti-rust hardware/backing plates. Thanks

Hey Don,
The 17-1/2" wheel listing is just a guideline for hub size, because wheels that are too big have a hard time mounting to some hubs due to the lack of surface area. So it won't affect the fit of brakes, and because you have the 7k Dexter hub and drum on your 2022 Grand Design Momentum 350G, here's what you'll need:
- Electric Trailer Brakes - Self-Adjusting # AKEBRK-7-SA
- Mounting Bolts and Hardware # BRKH12
These brakes have an E-coating on the backing plates, and the hardware is zinc-coated so you won't face issues with rust.

Hey Don, how did the self-adjusting brakes and hardware work out on your Momentum 350G? Those E-coated backing plates and zinc hardware should hold up well against rust. Your update could make it easier for others with the same setup.
