travel trailer brakes

had about 10 minutes of free time today...long enough to hook the cord to the truck and check a couple quick things...the brake lights do come on on both the truck and trailer when the truck brakes are applied. When the truck brakes are applied, I can't hear any hum near any of the 4 wheels, however when the slide lever is applied on the brake controller itself, i can hear the hum on 3 of the 4 tires, the two on the curb side and the rear of the other side, and nothing or very slight on the one on the front tire of the other side. The blades and the slots on the plug and the truck are all clean and clear...I also pulled the break away switch and didn't hear any pulsing at the tires. hoping to get a bit of time tomorrow or friday to start pulling tires and visually inspecting the brakes...on vacation so tinker time is hard to come by when it's meant to be family time. any other thoughts and leads would be appreciated...thank you to the two that have posted so far...helpful info so far. i like the idea of the rewired brakes

I have that controller, you won't hear the brakes just by pushing the brake pedal down while stopped.

I had the identical problem to what you are describing at the start of this season, what I found was the connector between the controller and the wiring harness itself. The connector is only about 6 inches away from the controller, and it appeared okay, and my lights on the controller appeared okay. When I touched that connector with my hand it came apart. I plugged it back together firmly and all worked well. I was shocked, since I had been working with my meter and banging my head on the brick wall.. that connector appeared perfectly fine and since the lights worked...... I never thought to check it.
