Dino Crescentini and Wayne Schaack Discuss Brake Pad Performance: The Impact of Shims and Friction Material Quality

When it comes to braking systems, there’s more than meets the eye. Dino Crescentini and Wayne Schaack, two seasoned professionals in the automotive brake industry, recently shed light on the critical factors that influence brake pad performance, including the brake disc, in an engaging discussion. The conversation highlighted how shims and the quality of friction materials play pivotal roles in braking efficiency, noise reduction, and overall durability. Here, we delve into their insights to understand why these components are essential and how they contribute to optimal braking performance.

Introduction to Brake Pads

Brake pads are a crucial component of a vehicle’s brake system, playing a vital role in ensuring safe and reliable braking performance. These essential parts are designed to convert the kinetic energy of a moving vehicle into heat energy, which is then dissipated, allowing the vehicle to come to a stop. The construction of brake pads involves a careful blend of raw materials, including metallic friction materials, organic materials, and other additives. Each of these materials is selected for its unique properties that contribute to the overall braking performance.

Metallic friction materials, for instance, are known for their durability and high friction coefficient, which is essential for effective braking. Organic materials, on the other hand, offer a quieter and smoother braking experience. The combination of these materials ensures that brake pads can provide optimal performance under various driving conditions. The manufacturing process of brake pads is meticulously designed to ensure that these materials are blended and processed correctly, resulting in a product that meets the high standards required for safe and efficient braking.

The Overlooked Role of Shims in Brake Pads

Shims are a crucial yet often underestimated component of brake pads. Crescentini and Schaack emphasized that a shim’s design and material significantly impact the pad’s performance. They explained how shims serve as a dampening layer between the brake pad and caliper, reducing noise and vibrations during braking. However, the effectiveness of shims depends on their construction and how well they align with the brake pad design.

Key takeaways about shims include:

Shape Matters: Shims should match the brake pad’s contour precisely. Poorly designed or consolidated shims that don’t cover critical contact points can lead to uneven wear and noise issues.
Material Quality: Rubber-steel-rubber shims, a common choice, need to maintain their integrity under high pressure. Inadequate materials can degrade quickly, exposing the caliper to direct steel contact, resulting in noise and reduced braking performance.
OEM vs. Aftermarket: While OE (Original Equipment) shims are tailored to exact specifications, aftermarket solutions often sacrifice quality to meet cost constraints. This can compromise long-term reliability.

Metallic Friction Materials: Beyond Formulation

While friction material often takes center stage in brake pad discussions, Crescentini and Schaack highlighted that quality goes beyond the formulation. Even identical formulas can yield vastly different results depending on the source and quality of the raw materials.

Brake lining plays a crucial role in enhancing braking efficiency and protecting braking components. It acts as a barrier that increases friction and prolongs the lifespan of brake parts, similar to brake pads, and is essential for maintaining vehicle safety and performance.

Factors affecting friction material performance:

Ingredient Sourcing: Premium materials ensure consistent performance, reduce rotor wear, and maintain a smooth braking surface throughout the pad’s lifecycle.
Manufacturing Process: The art and science of creating brake pads extend to how the ingredients are processed. Poorly processed materials can lead to inconsistent performance, noise, and dust over time.
Long-Term Durability: Inferior ingredients may perform adequately in initial tests but can break down under prolonged use, leading to scoring on the rotor and noise issues.

The Backing Plate: A Foundation for Success

The backing plate is another component that plays a vital role in ensuring brake pad stability and alignment. Crescentini pointed out that flatness and dimensional accuracy are critical for optimal performance. Without proper attention to the backing plate’s construction, even the best friction material and shims can fail to deliver the desired results.

Why Quality Matters in Reducing Brake Noise

Both experts emphasized the importance of not cutting corners in brake pad manufacturing. While cost constraints are a reality, quality materials and precise engineering ensure that the brake pad performs reliably over its lifetime. High-quality materials and precise engineering also help in reducing brake squeal, which can be caused by vibrations between components and the material properties of the pads.

As Crescentini aptly put it: “If I’m paying good money for a product, I expect it to work not just out of the garage but over time.” This philosophy underscores why DFC’s approach prioritizes superior materials, rigorous testing, and adherence to OEM specifications in all its products.

Performance Testing and Validation

Performance testing and validation are critical steps in the development and manufacturing of brake pads. These processes involve evaluating the braking performance of brake pads under various conditions, including different temperatures, speeds, and loads. The goal of performance testing is to ensure that brake pads meet the required safety and performance standards while also providing a comfortable and quiet braking experience for drivers.

During performance testing, brake pads are subjected to a series of rigorous tests, including:

Friction Coefficient Testing: This test measures the friction coefficient of the brake pad, a critical factor in determining its braking performance. A high friction coefficient indicates better stopping power, which is essential for safety.
Braking Performance Testing: This test evaluates the braking performance of the brake pad under various conditions, such as different speeds and loads. It ensures that the brake pad can perform reliably in real-world driving scenarios.
Noise Testing: This test measures the noise level of the brake pad during braking. Brake noise can be a significant concern for drivers, and this test helps ensure that the brake pad provides a quiet braking experience.
Wear Testing: This test evaluates the wear rate of the brake pad over time. Understanding the wear characteristics is crucial for determining the lifespan and maintenance requirements of the brake pad.

The results of these tests are used to validate the performance of the brake pad and ensure that it meets the required safety and performance standards. Additionally, the data collected during performance testing is used to optimize the design and manufacturing process of the brake pad, ensuring that it provides optimal braking performance and a comfortable and quiet braking experience for drivers.

In addition to performance testing, brake pads are also subjected to various validation tests, including:

Dynamometer Testing: This test evaluates the braking performance of the brake pad on a dynamometer, which simulates real-world braking conditions. It provides valuable data on how the brake pad will perform in actual driving situations.
Vehicle Testing: This test evaluates the braking performance of the brake pad on a vehicle, under various driving conditions. It ensures that the brake pad performs well in real-world scenarios.

OE Brake Pad Replacement Focus Keyphrase: Friction Issues and the Reality

Understanding Friction Brakes and Brake Pads

Friction brakes are a cornerstone of your vehicle’s braking system, crucial for ensuring safety and performance. At the heart of this system are the brake pads, which are responsible for creating the friction needed to slow down or stop your vehicle. When you press the brake pedal, brake fluid transmits this force to the caliper piston, which then presses the brake pads against the brake rotors. This contact converts the vehicle’s kinetic energy into heat, effectively reducing speed.

Brake pads are engineered to endure the high temperatures generated during braking. They are typically composed of a blend of materials such as metals, ceramics, and organic compounds, each chosen for their ability to withstand heat and provide reliable performance. The brake caliper, which houses the brake pads, plays a pivotal role in this process. It ensures that the pads are correctly positioned to engage with the brake rotors or drums.

Understanding the interplay between these components—brake pads, brake fluid, brake pedal, brake caliper, and brake rotors—is essential for maintaining a well-functioning braking system. Regular inspections and maintenance can help ensure that each part is performing optimally, contributing to the overall safety and efficiency of your vehicle.

The Complexity of Friction and OE Brake Pad Replacement

When it comes to replacing brake pads, many technicians and vehicle owners believe that returning to the original equipment (OE) brake pads is the best solution. However, as automotive industry veterans Dino Crescentini and Wayne Schaack explained in a recent discussion, the reality is more complex.

Brake servicing is a critical aspect of vehicle maintenance, requiring professional attention to ensure safe driving and prevent major brake issues. Regular brake inspections and maintenance are essential to avoid the risks associated with neglecting brake care.

With over 44 years of experience in the automotive aftermarket, Wayne Schaack shared insights into the challenges technicians face when addressing brake performance issues. Dino Crescentini, co-founder of Dynamic Friction Company, elaborated on how replacing OE pads may not always resolve the underlying problems.

The Myth of Identical OE Replacement Parts

One of the key questions Schaack raised was whether OE brake pads purchased years after a vehicle’s production are the same as the original parts installed during manufacturing. The consensus? It’s unlikely.

After production ends, OE manufacturers often switch to “OE service parts,” which are high-quality but differ from the original specifications. In older vehicles, these parts might even be generic aftermarket products marketed under an OE label. Brake wear can significantly impact vehicle safety and performance, making regular inspection and maintenance crucial to ensure brakes function effectively and to prolong their lifespan.

Why OE Brake Pads May Not Solve the Problem

Even if technicians opt for OE pads, the issue might not lie in the friction material itself. Key factors such as rotor condition, caliper retraction, and overall system wear can significantly impact braking performance.

The caliper bracket plays a crucial role in the brake system’s functionality, and issues with it can lead to problems such as sticking calipers, which affect overall braking performance.

Common Contributing Factors: Brake Wear

Caliper Retraction Issues: Over time, calipers may lose their ability to fully retract due to seal wear or degraded guide pins. This can cause the brake pad to remain in contact with the rotor, leading to uneven wear or excess heat.
Rotor Build-Up: Brake pad materials leave a thin film on rotors. If the rotor has slight run-out (deviation from flatness), the pad can deposit unevenly, creating the illusion of a warped rotor.
Environmental Impacts: Corrosive road salts and brine used in colder climates can degrade brake components, affecting the interaction between pads, rotors, and calipers.
Brake Hose Issues: A malfunctioning brake hose can restrict fluid flow, leading to problems such as the caliper piston not fully retracting. This can cause uneven brake pad wear. It is important to check the condition of the brake hose and ensure it is not blocked or crimped to maintain proper brake function.

Why Brake Rotors and Calipers Matter

The discussion highlighted the critical role that rotors and calipers play in brake performance. For example, attempting to cut rotors to remove material build-up may not resolve underlying caliper issues, potentially leading to recurring problems.

Understanding the unique maintenance requirements of disc brakes is essential for maximizing brake performance and preventing costly repairs. Schaack emphasized the importance of maintaining all components in the braking system, including hardware and guide pins, to ensure long-term performance.

The Role of High-Quality Aftermarket Solutions

For those struggling with friction-related issues, the solution may lie in premium aftermarket brake products. Companies like DFC focus on producing parts that meet or exceed OE standards, offering consistency and reliability for technicians and vehicle owners.

The condition of the rear brakes can significantly affect overall brake performance. It’s crucial to consider them during maintenance to ensure the brake system’s integrity and prevent issues like uneven wear on brake pads.

Signs of Brake System Failure

A malfunctioning brake system can pose a significant safety risk, making it crucial to recognize the warning signs of brake system failure. Here are some common indicators that your braking system may need attention:

Spongy Brake Pedal: If your brake pedal feels spongy or soft when pressed, it could indicate air in the brake lines or worn-out brake pads. This can compromise your braking efficiency and should be addressed promptly.
Grinding or Screeching Noises: Unusual noises when applying the brakes often signal worn-out brake pads or warped brake rotors. These sounds are a clear indication that your brake components need inspection and possibly replacement.
Vibrations When Braking: If you experience vibrations through the brake pedal or steering wheel when braking, it may suggest warped brake rotors or an imbalance in the braking system. This can affect your vehicle’s stability and stopping power.
Increased Stopping Distance: A noticeable increase in the distance required to stop your vehicle can be a sign of worn-out brake pads or other brake system issues. This can be particularly dangerous in emergency situations.
Brake Fluid Leaks: Leaking brake fluid is a serious issue that can indicate problems with the brake master cylinder or brake lines. Brake fluid is essential for transmitting the force from your brake pedal to the caliper piston, and any leaks should be repaired immediately.

If you notice any of these signs, it’s crucial to have your brake system inspected and repaired by a professional mechanic. Addressing these issues early can prevent more severe problems and ensure your vehicle remains safe to drive.

Key Takeaways for Technicians and Consumers

OE Parts Aren’t Always the Same: Don’t assume that “OE” brake pads purchased later will match the original factory-installed parts.
System Health Is Critical: Evaluate the entire braking system, including calipers, rotors, and hardware, during a brake job.
Premium Aftermarket Options: High-quality aftermarket pads and rotors often deliver performance comparable to or better than OE products.

For the best results, consider DFC’s advanced brake solutions, including their DFC 4000 HybriDynamic Brake Pads and GeoSpec Coated Rotors, which are engineered to meet the needs of both technicians and consumers. By focusing on system-wide performance, you can ensure a safer, more reliable braking experience.

Conclusion and Further Reading
