That's false when it comes to drums, dirt and rocks get in them and take them out. They rust fiercely too. Their braking power is a joke, brake fade fast. ABS doesn't work well on drums. The only up side to drums is parking brake holding, that is it. Anyone that knows anything about brakes knows discs are 100x better in every way except parking brake.
Just telling you what they told me. Yeah, they are better..but not neccessary.
