you need to adjust them. I turn the adjusters until the tire can barely turn, and then back off both sides an equal amount. you have to both listen and feel the tension on the brakes as you turn the tire by hand, and make both sides drag equally. That's how I do my 4 wheel drums, and I don't even hardly need to hold the steering wheel when I brake hard.
but disks are the best way to go.
