BFL13, thanks for your input. It appears my response was not all that clear.
My plan is to replace the brake assemblies only and not the axles. I am replacing the current brake assemblies (backing plate, shoes, and magnets) which are made for the 5.2 K axles and currently on the unit and installing brake assemblies that are made for the 7K axles on the existing 5.2K axles installed on the unit. Physically the brake assemblies are interchangeable but the lining compound on the 7K shoes is more aggressive.
But why do you think the existing brakes are inadequate? The 5200s were just fine with my similar trailer. You asked about others' experiences.
What do you want more than that and why? I would suspect the truck if you can't stop properly now. You might also have a brake controller "issue" where there is not enough voltage getting back to the trailer brakes. You can test for that with a voltmeter. Last thing I would consider is the size etc of the OEM 5200 brakes as such.
