When it comes to safe and effective braking, the material of your brake pads matters more than you might think. One specific type—Low-Metallic NAO brake pads—offers a unique balance of performance, cost, and durability. But what exactly are they, and when should you choose them over ceramic or semi-metallic pads?
Let’s break it down.
What Are Low-Metallic NAO Brake Pads?
Low-Metallic NAO (Non-Asbestos Organic) brake pads are made primarily from organic materials like rubber, glass, and resins, but include small amounts of metal—usually copper or steel—to improve braking performance.
Unlike semi-metallic brake pads, which can be over 50% metal, low-metallic NAO pads contain around 10–30% metallic content. This blend enhances stopping power and heat dissipation without making the pads too noisy or abrasive.
These pads are not fully copper-free but typically contain less copper than older semi-metallic options, making them more compliant with modern environmental standards in many regions.
Key Characteristics of Low-Metallic NAO Brake Pads
Friction and Braking Power
Low-metallic pads deliver strong braking performance, especially in high-temperature conditions. This makes them reliable in stop-and-go traffic or urban driving where brakes are used frequently.
Noise and Dust Generation
The trade-off? They tend to produce more noise and brake dust than ceramic pads. While it’s not extreme, you might notice more dust on your wheels and occasional squeaks during slow stops.
Heat Dissipation
Thanks to their metallic content, these pads handle heat better than organic-only materials. They’re less likely to fade under heavy braking, which is crucial for consistent performance in city driving or light towing situations.

Low-Metallic NAO vs Semi-Metallic Brake Pads
Composition and Material Differences
Semi-metallic pads are made with 30–65% metallic content and are more aggressive in performance and feel. Low-metallic pads, with their reduced metal levels, are less abrasive and quieter but slightly less powerful in extreme conditions.
Performance Comparison
Semi-metallic pads perform better under high stress and heavy loads. They’re ideal for performance vehicles or heavy-duty applications. Low-metallic NAO pads strike a balance between comfort and braking power for everyday use.
Comfort and Wear
Low-metallic pads are gentler on rotors and often provide a smoother pedal feel. Semi-metallic pads can wear down both themselves and the rotor faster due to their abrasive nature.
Pros and Cons of Low-Metallic NAO Brake Pads
Pros
- Solid braking power across a wide range of temperatures
- Affordable and widely available
- More rotor-friendly than fully metallic pads
- Good for daily driving and light-duty use
Cons
- Higher brake dust production than ceramic
- Moderate noise levels, especially when cold
- Shorter lifespan than ceramic or some high-quality semi-metallic pads
When to Use Low-Metallic NAO Brake Pads
Ideal Use Cases
- Daily Commuting: These pads are perfect for city and suburban drivers who deal with stop-and-go traffic regularly.
- Mid-Size Passenger Cars: Sedans, compact cars, and hatchbacks benefit from the balance of power and comfort.
- Light Towing or Load: Occasional towing or carrying loads? These pads can handle it without overheating.
When to Avoid Them
- If you need ultra-quiet braking or have a luxury car, ceramic pads may be better.
- For off-road or high-performance driving, semi-metallic or racing pads offer better endurance.
- If you’re allergic to dust buildup on your wheels, consider dust-free ceramic options.
Compatibility and OEM Considerations
Many vehicles—especially compact and mid-size passenger cars—come standard with Low-Metallic NAO pads from the factory. They’re an OEM choice for brands looking to balance cost, performance, and comfort.
If you’re replacing OE pads, it’s often best to stick with the same type, unless you have a specific performance goal in mind.
Always check your owner’s manual or consult your mechanic to see if switching brake pad types will affect your vehicle’s braking system or warranty.

Low-Metallic NAO Brake Pads vs Ceramic: Which One’s Better?
Performance vs Cleanliness
- Low-metallic pads provide better raw braking performance.
- Ceramic pads are cleaner, quieter, and more comfortable, but may sacrifice stopping power under heavy loads.
Longevity and Rotor Wear
- Ceramic pads generally last longer and are less harsh on rotors.
- Low-metallic pads may wear faster but provide more aggressive braking response.
Price Difference
- Low-metallic pads are usually more affordable.
- Ceramic pads are pricier but often make up for it with longer lifespan and reduced maintenance (less dust).
Environmental Considerations: Are Low-Metallic Pads Copper-Free?
Not entirely. While they contain less copper than traditional semi-metallic pads, low-metallic NAO pads are not considered copper-free.
Some states, like California and Washington, have enacted regulations requiring brake pads to be below certain copper thresholds. If environmental compliance is a priority, make sure to look for products marked with the LeafMark (indicating compliance with copper regulations).
Final Verdict: Should You Choose Low-Metallic NAO Brake Pads?
Low-Metallic NAO brake pads are a practical, well-balanced choice for everyday drivers who need reliable braking performance without the high cost of performance-grade components. They offer solid stopping power and improved heat dissipation over organic pads, making them ideal for city driving, commuting, and occasional highway use. However, they do come with some trade-offs—namely, more brake dust and moderate noise. If your priorities are clean, quiet braking or heavy-duty performance, ceramic or semi-metallic pads might suit you better. But if you’re looking for OEM-level quality, decent durability, and consistent performance at a reasonable price, Low-Metallic NAO brake pads are a smart option.
