Question:
I was looking at trailer hydraulic brake assemblies and drum/hub’s. I measured my current breaks at 9 1/2 inches pad to pad and the drum measured 11 1/2 inches. Would 10” work? I’m not sure if I am measuring wrong or if they are just that worn. I was looking at part AKHD-545-35-EZ-K. My trailer is dual axle and the tongue say 6000lbs. Does that mean each axle is rated for 3000lbs and the assemblies should be too? Would 3500lbs work? Wheels are 15” 5 4.5.

Thanks for reaching out again, Devin!
A 1/2" difference sounds like a lot until you think about it just being a 1/4" off of each brake pad - so that's definitely feasible especially if it's been quite a while since they were changed.
With all that being said, it's never a bad thing to verify fitment. So, for the brakes you're looking at the Hydraulic Trailer Brake Kit # AKFBBRK-35 which are free backing and mount using a 4-bolt pattern with the holes measuring 2-7/8" apart from each other (4" for the ones across from each other).
Then for the hub/drum you'll want the Easy Grease Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K which has Inner Bearing L68149, Outer Bearing L44649, and a grease seal with a 1.719" ID.
If all of this matches what you currently have then these parts will fit perfectly on your trailer!
