5 reasons why disc brakes are inferior to drum brakes

There is an opinion that disc brakes are much better and more efficient than drum brakes. They say, therefore, they are gradually being changed to disc brakes. The AvtoVzglyad portal debunks the most popular myths about “drums” and explains why they are far from worse than disk ones.

"Drums" continue to be put on the rear axle of many cars. At the same time, "experienced" drivers consider them inefficient. Yes, and marketers quickly realized that if a car has disc brakes at the back, then this fact is perceived by buyers as an advantage of the car, and began to offer them as an option. Let's see if it's worth overpaying and if the "drums" are so bad.

In fact, drum brakes have a number of undeniable advantages. For example, they are perfectly protected from external influences, which is why they are placed on the rear axle, because a lot of dirt flies back. And if the "drums" are changed to "disks", then the latter will wear out faster. Especially the inner part of the disks, because it is simply bombarded by stones and sandblasting. And the pads will need to be changed more often. That is, the owner will pay more for the service on the service. Another nuance: if you drive through an ice puddle, the disks can go screw, but nothing will happen to the “drums”.

The third undoubted plus of the "classic" mechanisms is that they have a high braking force. The closed design makes it possible to make the friction area of ​​the pads against the drum surface very large. This improves braking performance. Therefore, "drums" slow down the car no worse than disc brakes.

That is why drum brakes are still in use on many budget cars. People's small cars simply do not need highly efficient "cars" to upset the car at high speeds. At the same time, the risk of overheating of the brakes is not so terrible, because people's cars often drive around the city, where speeds are low.

Let's not forget that the pads of the "drums" wear out more slowly, so the first car owners, as a rule, do not think about replacing them. By the way, pads can “walk” more than 70 km, while spare parts for disc brakes can not withstand even 000 km. So frugal people should think about it.

Let's not ignore the fact that wear products accumulate in the "drums" and then the deceleration efficiency drops. That being said, let's keep in mind that if you blow out the mechanisms with air at every maintenance, all the dirt can be quickly removed. But the disc mechanisms need regular cleaning and lubrication. Hence the increased cost of their maintenance.
