The importance of brake pads cannot be overstated, as they are a crucial component in vehicle safety. When purchasing, it's not enough to just pick any brake pad. Certifications play a significant role in determining whether a brake pad is fit for purpose.

What is acceptable for brake pads?

When shopping for brake pads, it's essential to know what’s acceptable in terms of standards and quality¹. But how do you determine if a brake pad meets the necessary criteria? Let's dive into the key factors that define a brake pad’s validity.

Acceptable brake pads must meet specific industry standards for safety and performance². This includes durability, noise reduction, and heat dissipation. Certifications³ ensure that the brake pads have passed stringent tests and are reliable in all conditions.

The most important factor in brake pad selection is their safety and performance under various driving conditions. Brake pads must meet certain criteria to be deemed acceptable. These include durability, noise levels, and heat resistance. Brake pads that are too soft can wear out quickly, while those that are too hard may cause excessive noise or damage to the rotor.

Key Aspects to Consider in Brake Pad Acceptability:

1. Durability: Brake pads are exposed to constant friction, heat, and pressure. Their material must be durable enough to withstand these conditions without excessive wear. The material composition directly impacts how long the brake pads last before they need to be replaced. Higher-quality materials such as ceramic or semi-metallic composites⁴ often provide longer-lasting performance.

2. Stopping Power: The brake pads should deliver effective and consistent stopping power under a variety of conditions. Whether you are driving in wet or dry conditions, the pads must be able to apply the necessary friction to slow down or stop the vehicle safely. This is tested through standardized tests, ensuring the brake pads meet regulatory requirements for performance.

3. Heat Dissipation: Brake pads need to dissipate the heat generated from friction when applied to the brake disc. If the heat is not managed correctly, brake fade can occur, reducing braking efficiency. Brake pads should have good thermal conductivity to avoid brake fade and maintain performance over time.

4. Noise Reduction: The composition and design of brake pads should minimize unwanted noise. While some noise may occur due to the nature of the braking process, excessive noise often indicates poor material quality or incorrect fit. Pads should be designed to reduce squeaks and grinding.

5. Environmental Impact: Environmental factors such as dust production and harmful emissions from brake pads are becoming more relevant. Green certifications and low-dust materials help ensure that brake pads comply with environmental standards. This is particularly crucial as consumers and regulatory bodies push for more eco-friendly products.

What do the codes on brake pads mean?

Ever noticed the codes on brake pads and wondered what they mean? These codes can tell you a lot about the brake pads' specifications and performance⁵. Let’s decode these markings and understand their significance.

The codes on brake pads indicate various specifications, such as material composition, manufacturer, and approval⁶. These codes are essential for ensuring that the brake pads meet required safety and quality standards.

Brake pad codes typically consist of a combination of letters and numbers that indicate several important factors. The first part of the code often refers to the manufacturer or the specific part number⁷ of the brake pad. This is useful when ordering replacement parts to ensure compatibility.

What Brake Pad Codes Tell You:

1. Manufacturer Identification: The first section of the code usually identifies the manufacturer or brand⁸ of the brake pad. This helps customers verify the origin of the parts and check for any recalls or known issues with that specific brand.

2. Friction Material Composition: Codes may also indicate the type of friction material used⁹. Brake pads are generally categorized into three types based on their material composition:

   • Organic: Made from materials like rubber, carbon, and resin, organic brake pads are typically quieter but wear out more quickly.
   • Semi-metallic: These pads contain a blend of metals, providing better durability and heat dissipation, but they can produce more noise and dust.
   • Ceramic: Known for their long lifespan, ceramic pads offer low dust and noise, and they perform well in both high- and low-temperature conditions.

3. Approval Certifications: Certification codes such as the ECE R90¹⁰ or FMVSS 121standard are essential to ensure the pads meet safety requirements in different regions. For example, in Europe, brake pads with the R90 certification guarantee compliance with EU standards for braking performance and noise levels.

4. Performance Ratings: Some codes also provide performance information, such as the temperature range at which the brake pads perform optimally. This is important in choosing the right pad for specific driving conditions (e.g., high-performance driving, towing, etc.).

5. Part Numbers and Cross-References: The part number on brake pads often helps match them with the specific vehicle or system they are designed for. It's crucial for ensuring compatibility with your vehicle’s braking system.
