No. Rear braking systems vary by vehicle; while rear drums are still used on some models, the majority of new cars use rear disc brakes or a disc brake with a drum-style parking brake, and the trend is toward discs on both axles for better performance.
The question touches on how modern braking systems are configured across different cars, trims, and regions. While drums were once standard on many rear wheels, advances in braking technology, ABS, and driver-assistance systems have pushed many manufacturers to adopt rear discs as the norm. Some budget or region-specific models still rely on rear drums, and some designs employ drum-in-disc arrangements to house the parking brake without sacrificing a full disc kit.
Current Landscape: How rear brakes are configured today
To understand what you’ll typically find on contemporary vehicles, here is a snapshot of common rear-brake configurations.
- Rear disc brakes on most modern passenger cars, especially in mid-range and higher trims, often paired with front discs for balanced braking performance.
- Rear drum brakes on some entry-level trims or budget models, where cost savings are prioritized and maintenance patterns are region-specific.
- Disc brakes with an integrated drum for the parking brake (drum-in-disc systems), which use a small drum inside the rotor to operate the parking brake without a separate drum assembly.
- Hybrids and some electric vehicles may still use rear discs because regenerative braking reduces reliance on hydraulic brakes, but the physical braking hardware remains a disc setup in most cases.
Overall, rear brakes are not universally drums on today’s vehicles. Disc configurations—whether alone or paired with a drum-style parking brake—are now the prevailing design in most markets, with drums persisting mainly on lower-cost or region-specific models.
Historical context and reasons behind the split
Why did drums persist in some cases, and why are discs dominant today? The history helps explain current patterns and why you still see drums on certain models.
Why drums persist in some models
Drum brakes are cheaper to manufacture and can deliver effective parking brake performance without adding hydraulic complexity. They can also offer favorable wear characteristics in high-volume production and are robust in certain climates and service environments.
Benefits of rear discs
Disc brakes provide better heat dissipation, more consistent stopping power under repeated braking (less fade), easier integration with modern anti-lock and stability systems, and clearer diagnostics when service is needed. These advantages drive their prevalence on newer and mid-to-high-end models.
What drivers should know
For buyers and owners, understanding the rear-brake setup can help with maintenance planning and informed purchasing choices.
How to verify what your car uses
Check the owner’s manual or the vehicle specifications on the manufacturer’s site. If you can safely inspect the rear wheel area: a visible rotor behind the wheel indicates rear discs; a drum housing behind the rotor or backing plate indicates rear drums. For a definitive answer, consult the service records or a dealership.
Maintenance considerations include the typical replacement intervals for pads (often longer for drums, but varies by design), the availability and cost of parking-brake components, and whether the setup uses a drum-in-disc mechanism that may have different service procedures than a standard disc and caliper.
Summary
The rear braking system is not limited to drums. While rear drums still appear on some budget or regional models, most new cars use rear discs, and some employ drum-in-disc parking-brake designs. The choice reflects a balance of cost, performance, and maintenance practices, with discs (and disc-based parking brakes) becoming increasingly common across the mainstream market.
Who makes brake rotors for Lexus?
Akebono and Advics in the ASIN Group and they make ALL Lexus Brake Rotors and Pads. They are also all only made in Japan and the US. Actually, advics high carbon rotors are the OEM rotors They are literally piece to piece, same to stock rotors. My 15 es 350 has 125k miles on it and the rotors are stock advics.
Can a car have both drum brakes and disc brakes?
Does your vehicle have disc brakes up front and drum brakes in the rear? This setup is still common in many new cars, especially compact and midsize sedans. While it might seem like an odd mix of new and old technology, this combination has a practical reason. Automakers don't make these decisions randomly.
Do cars still have rear drum brakes?
However, drum brakes are still often used on the rear wheels, and for parking brakes. Some vehicles utilize a "drum-in-hat" parking brake, where the brake shoes are arranged inside the center portion (hat) of a disc brake rotor, which acts as the drum.
Are drum brakes only in the rear?
If you are looking to utilize drum brakes, it is suggested that they only be used on the rear wheels, as they tend to be less reliable over time. Almost no vehicles have been produced with front drum brakes since 1986.
