Trailer Brake Dust Cover?

[sandy43]

Newer trailer brakes tend to produce lots of carbon like dust from the brake drum. It's obvious to see on wheels and wheel wells. This is becoming a problem for me, because it blowing up on the underside of the slides and eventually getting on the carpet when slides are extended.

Has anyone seen this happen to their RV?

I've been told they make a brake dust cover that goes between hub and wheel, which can eliminate most of the dust from getting on wheels and hopefully the under side of your trailer. This is new to me. Anyone try this or heard of these?

Thanks
