I've been putting this off and driving around town with the intention of getting to it later. But I've found that the brakes are suddenly no longer pulling to the left. In fact, the truck stays straight when you brake and take your hands off the wheel. Is it possible for this kind of problem to correct itself? I do notice that the left front drum is hotter than the right after driving in traffic, but that has equaled out some over the past few days. The front shoes are the ones that were on there when I got the truck. The backs are new. Maybe they just needed to wear in?
