Why do new cars still have drum brakes?
Drum brakes persist on some new cars because rear drums offer cheap, reliable braking and a straightforward parking-brake solution, especially on base trims or in cost-conscious markets. Front brakes, by contrast, are typically discs to handle higher heat from aggressive braking. This article explains the reasons, how brakes are configured today, and where you’re most likely to still see drums on new cars.
How braking systems are configured in modern cars
Understanding the typical layout helps explain why drums linger on some models. Most modern cars rely on disc brakes on the front axle for maximum heat dissipation and stopping power, while the rear axle may use discs or drums depending on cost, packaging, and intended use. ABS and electronic controls have standardized how brakes operate, but the fundamental trade-offs between discs and drums remain relevant.
Front vs. rear braking configuration
Front discs handle the majority of braking because weight shifts forward during stopping, generating more heat and wear on the front brakes. Rear brakes provide additional stopping force and help stabilize the vehicle, but their job is typically less demanding. This division allows automakers to optimize performance, cost, and packaging by choosing rear drums or rear discs based on the model.
Why drum brakes remain on some new cars
Cost and packaging considerations
Drum brakes on the rear axle are often chosen for budget-focused models because they are cheaper to manufacture and assemble. They use simpler hardware, fewer components, and can be easier to source at scale, which helps keep vehicle prices down and production lines efficient.
- Lower hardware costs for rear brake assemblies compared with rear discs and calipers.
- Simplified manufacturing and supply chain benefits, particularly for high-volume models.
- Smaller, lighter packaging requirements in some rear-axle configurations when drums are used.
In short, cost-sensitive design decisions and the desire to keep entry-level models affordable drive the continued use of rear drums in some new cars.
Parking brake integration
Drums provide a straightforward platform for a mechanical parking brake. A cable can pull shoes inside the drum to hold the car securely, with minimal electronics and fewer moving parts. This simplicity appeals to models that rely on a robust, easily serviced parking brake rather than an electronically controlled system.
- Ease of integrating a mechanical parking brake without complex actuators or sensors.
- Durability and reliability in a broad range of climates and driving conditions.
- Reduced dependence on electronic systems, which can be advantageous in certain markets.
These characteristics make rear drums attractive for affordability and maintenance reasons, particularly on low‑trim variants.
Market and model variation
Not every market or brand uses rear drums the same way. In many regions, drums survive on some entry-level or smaller vehicles, while higher-trim models and many newer designs use rear discs for better overall braking performance and progress toward future safety standards. The decision often reflects a combination of regional preferences, repair networks, and consumer expectations.
- Entry-level trims and certain regional models may rely on rear drums to keep costs down.
- Some vehicles use rear drums on specific markets where service infrastructure favors simple components.
- In other markets, rear discs dominate across most trims for improved brake performance and warranty profiles.
Overall, drum brakes persist because they fit a particular balance of cost, reliability, and packaging in select models and regions.
Where you’ll still see rear drum brakes on new cars
Despite the move toward discs, there are still common scenarios where drum brakes appear on new vehicles. If you’re shopping for a budget-focused model or buying in markets with price sensitivity, you may encounter rear drums on the base versions.
- Budget or entry-trim models on small or affordable sedans and hatchbacks in price-sensitive markets.
- Markets or brands that prioritize robustness and a simple mechanical parking brake over advanced electronic braking systems on the rear axle.
- Specialized utility vehicles or fleet-oriented models where cost per unit and straightforward maintenance drive the choice.
In practice, rear drum brakes are most likely to appear where cost control and straightforward servicing are top priorities, rather than where performance metrics are the primary goal.
Safety, performance, and maintenance considerations
Braking performance depends on how well a vehicle is maintained and how the brakes are designed for the intended use. Drums and discs each have strengths and trade-offs that matter for safety and daily driving.
- Heat management: Disc brakes generally tolerate repeated heavy braking better than drum brakes, which can fade when overheated.
- Weather and moisture: Discs tend to perform more consistently in wet conditions; drums can be affected by moisture when first applied after a pause, though ABS can mitigate this issue.
- Maintenance: Drum brakes require periodic inspection and shoe replacement with occasional drum resurfacing; discs require pad replacement and rotor resurfacing or replacement. Both demand regular service aligned with the manufacturer’s schedule.
- Safety parity: When properly maintained, rear drums provide adequate braking force and reliable function, though the overall braking balance may differ from all-disc configurations.
Understanding these factors helps drivers know what to expect from their vehicle’s braking feel and maintenance needs, regardless of whether the rear brakes are drums or discs.
Summary
New cars still use rear drum brakes primarily to save costs and simplify the integration of a mechanical parking brake, especially on budget trims and in certain markets. Front brakes remain discs for superior heat management and stopping power. While the automotive industry has shifted many models toward rear discs for better overall performance, drums persist where cost and packaging considerations trump performance in everyday driving. For buyers, the key takeaway is that drum brakes are not an indication of poor safety—they are a deliberate design choice that hinges on cost, practicality, and market needs.
Are drum brakes still relevant today?
Cost-Effectiveness in Manufacturing
One of the biggest reasons drum brakes are still used, especially on the rear wheels of many cars, is cost. Drum brake systems are significantly cheaper to manufacture than disc brakes.
Why are drum brakes coming back?
And that is where the expense. Comes from but drum brakes also turn out to be more economical in service as they tend to last longer.
Which is safer, drum or disc brakes?
Disc brakes offer superior stopping power and heat dissipation, making them ideal for performance-oriented vehicles and demanding driving conditions. Drum brakes, with their cost-effectiveness and durability, are a practical choice for everyday vehicles and less intensive braking demands.
What new cars still use drum brakes?
You'll find rear drum brakes on the 2025 Nissan Versa and other similar affordable cars, too. That's because drum brakes are easier to make and assemble, built from cheaper materials, and can lower the price (and potentially maintenance costs) of cars equipped with them.
