When braking on the highway today I noticed that I had to turn the steering wheel a couple of inches to the right. I thinking that the passenger side trailer brake much be applying more strongly than the left and is pulling the rear to the TV to the right. I'm using an E-qual-izer for weight distribution and sway control. Are the passenger side brake receiving more voltage? Do the drum brakes need some manual adjustment? If needed can this be done without removing the drum?
