Efficiency and response
According to Mr. James Patterson, technical expert at the British Institute of Transport Technology (ITS UK), in the current car market, the two most popular types of brakes are disc brakes and drum brakes. Each type has its own advantages and disadvantages, suitable for each purpose of use and different vehicle segment.
Discs brakes are highly appreciated for their braking performance, especially at high speeds or in conditions where braking is urgent. The open device and the mechanism of pressing the brake pads into the rotary disc help transmit heat quickly, reducing the risk of brake failure due to overheating. This is the reason why sports cars and luxury tourist cars often use a four-wheel disc brake system.
In contrast, the drum brake has a closed structure, using a brake force to press on the inside of the drum to create resistance. Although it has high durability and lower production costs, drum brakes are prone to fading (reducing brake performance when the temperature increases during continuous use).
Cost and maintenance features
In terms of cost, drum brakes have a clear advantage. Cheaper and less require regular maintenance, this type of brake is often equipped for the rear wheels of popular vehicles, especially small urban vehicles. However, when repair is needed, replacing or cleaning the drum brake requires more complex techniques than disc brakes.
Mr. James Patterson assessed that disc brakes can dominate in harsh operating conditions. However, drum brakes still play an important role in vehicles with light loads or requirements for optimal costs. Their role should not be underestimated just because of their simpler texture.
The trend of combining both types
In fact, many car manufacturers are currently applying a combined model: disc brakes on the front wheel, which are the places with the greatest brake pressure, and drum brakes on the rear wheel, to balance efficiency, cost and durability. This is a popular solution on today's B and C-class sedans.
Depending on the purpose of use and technical characteristics of each vehicle line, both types of brakes have a certain stand. It is important that users clearly understand the advantages and disadvantages of each system to make appropriate choices, while ensuring periodic maintenance to maintain optimal braking efficiency.
