Brake problem 2013 Columbus 320RS (Electrical?)

After living with recurring brake problems on my Columbus 320 I finally changed out the brakes and put new seals, brakes, magnets and packed wheel bearings. Still not satisfiyed with the brakes and after checking the voltage to the brakes, it reads 10.2 volts. I thought someone said it should be 12.2 volts. If so, what and where do I look next? Brakes just don't seem to be applying hard enough when stopping.
"totally frustrated"

From what I was told it should read 12volts... Is the controller set to full power?? Did you check all your grounds?

You didn't mention adjusting the brakes?

BTW over the years I've found once you've adjusted them you have to go back and adjust them a few more times to get them "right"

I adjusted my sabre brakes not long ago after the trip, they seemed "ok" I then had to go back once again and gave them even more.

Now they'll rip your head off at full power!

BTW you have the same axles and brakes I have.

We did adjust the brakes and we're sure they are within "grabbing" distance of the drum. So in order to check out the controllerer, we by-passed the controller in my 2012 F250 and hooked up a new controller (can't remmber the name) and had the same problem. I'm guessing there's a ground problem because the 10.2 volts was coming from the shops trailer hook up. (a device that you plu the trailer into the shop tester without a truck) So, if it's a ground problem where do I start looking?

Start at your connections behind your backing plate and move forward.

The use cheap ass scotch locks that are a wiring no no!

I don't understand "backing plate". Please explain. What are scotch locks? Are they the screw on wire connectors vs the crimp connectors?

Sounds like you are experiencing resistance, have you checked the voltage at the truck plug, if it is ok start from there back to the axles cleaning all connections or replace them.
