The evolution of braking systems in the automotive industry has been marked by significant advancements, particularly the transition from drum brakes to disc brakes. This shift raises the question: Why are drum brakes not used anymore? Understanding the reasons behind this change requires a comprehensive analysis of the technological, safety, and performance factors that have influenced brake design over the years. This article delves into the intricacies of drum and disc brakes, comparing their functionalities and highlighting the factors that led to the preference for disc brakes in modern vehicles.
Drum brakes were once the standard in automotive braking systems. They operate by pressing brake shoes outward against a rotating drum attached to the wheel. This action creates friction, slowing down the wheel's rotation. The simplicity of their design made them a popular choice in early automotive engineering.
However, drum brakes have inherent limitations. The enclosed design can lead to heat build-up, causing brake fade under heavy use. Additionally, they are susceptible to water ingress, which can significantly reduce braking efficiency. For a deeper understanding of the differences between braking systems, consider exploring our comparison on Disc brakes vs drum brakes.
Disc brakes offer several performance and safety advantages over drum brakes:
Disc brakes are designed with an open airflow system that allows heat to dissipate more effectively. This reduces the risk of brake fade and maintains consistent braking performance even under strenuous conditions.
The exposed nature of disc brakes allows water to be shed quickly from the braking surface, improving performance in wet conditions compared to drum brakes, which can trap water inside the drum.
Disc brakes provide more linear and predictable stopping power, giving drivers enhanced control. This is particularly important in modern vehicles equipped with advanced driver-assistance systems.
With fewer moving parts and an easier inspection process, disc brakes require less maintenance and offer longer service intervals. This leads to lower long-term costs and increased reliability.
The automotive industry's focus on safety and performance has accelerated the adoption of disc brakes. Innovations in materials, such as ceramic composites, have enhanced the durability and effectiveness of disc brakes. These advancements have rendered drum brakes increasingly obsolete in modern vehicle designs.
Moreover, the integration of electronic braking systems, such as Anti-lock Braking Systems (ABS) and Electronic Stability Control (ESC), is more compatible with disc brake systems. The precise control required by these technologies is better facilitated by the responsive nature of disc brakes.
Regulatory bodies have set stringent safety standards that favor the use of disc brakes. The enhanced stopping power and reliability of disc brakes contribute to meeting these standards, promoting their widespread adoption. Vehicles equipped with disc brakes have been shown to have shorter stopping distances, which is crucial in preventing accidents.

While drum brakes are less expensive to manufacture, the cost of maintenance and the demand for higher performance have shifted the economic balance in favor of disc brakes. Consumers prioritize safety and performance, often willing to incur higher upfront costs for vehicles equipped with superior braking systems.
Additionally, advancements in manufacturing have reduced the cost of producing disc brakes, making them more accessible across various vehicle segments, including economy models.
Manufacturers like Chery and BYD have transitioned to disc brakes in their latest models. This shift aligns with consumer expectations for safety and performance in passenger vehicles. For details on Chery's implementation, visit our Chery Auto Parts section.
In commercial transport, the adoption of disc brakes enhances safety for heavy-duty applications. Brands like JMC have updated their fleets to include disc brake systems, acknowledging the importance of reliable braking in larger vehicles.
Disc brakes generate less noise and particulate emissions compared to drum brakes. The reduced environmental impact aligns with global efforts to minimize pollution from automotive sources. This consideration adds another layer to the reasons behind phasing out drum brakes.
Despite their advantages, disc brakes are not without challenges. They can be more susceptible to damage from debris due to their open design. Additionally, the initial cost remains higher than drum brakes, which can impact pricing in lower-end vehicle markets.
However, continuous improvements in materials and protective technologies are mitigating these issues, making disc brakes more robust and cost-effective over time.
The trend towards electrification and autonomous driving systems requires braking systems that offer superior performance and integration capabilities. Disc brakes are better suited for these advanced systems, suggesting their continued dominance in future vehicle designs.
