What size brakes on my 1991 Excella

I am the 3rd owner of a 25 ft, dual axle, 1991 Excella. My trailer brakes are not activating. My TV is a 2007 Ford F-250 with factory tow commander. I pulled all 4 trailer wheels apart yesterday and found magnet wires broken on two wheels which I repaired. Mechanically all 4 wheels look good, with no broken or loose parts, good shoe and brake pad movement and all magnet wear surfaces square. After 7 hours work it feels like the brakes slightly hit when manually activating the brake system, but when in drive, and in idle, and the controller manually activated to 100% the truck idles forward when I take my foot off the brake pedal, so no holding power. Later today I plan to hookup my friends F-350 to see if the problem is with the TV or the Airstream. Assuming that the issue is the same after the test I will focus on the trailer and brake system. Trying to get out in front of the issue I see etrailer sells complete brake assemblies as a package but not sure how to measure the brake size in order to purchase if needed. Do I measure the inside diameter of the drum? Any and all feedback on my situation as I have described it will be greatly appreciated.

My 25', 1988 Excella, uses the 10" brakes.

I put a set of the E-trailer brakes on my trailer last summer. They work okay. But maybe not "great".

I assume you have adjusted the gain and boost levels of your controller?

I have adjusted the gain all the way up to 10. I get the same results whether at level 1 or level 10. Thank you for taking the time to help troubleshoot and thanks for the review of the etrailer brakes. At this point they would be 100% better than I have at the moment but until I rule out the tow vehicle I can't be sure.
