What is a Brake Pad Chart and Why is Hawk's Important?
A brake pad chart is a table or diagram that summarizes the technical specifications and performance ratings of brake pads within a brand's lineup. Hawk's version is particularly respected in the automotive industry for its clarity and comprehensiveness. It serves as a one-stop reference to compare different pad compounds and their suitability for various applications. The importance of Hawk's chart lies in its role in decision-making. Without it, choosing a brake pad can be overwhelming due to the plethora of options available. The chart simplifies this by categorizing pads based on objective criteria. For instance, it helps distinguish between pads designed for aggressive street driving versus those meant for track use. By consulting the chart, you can quickly identify which pads offer the right balance of characteristics for your needs, such as high friction for spirited driving or low dust for daily convenience. This reduces the risk of selecting a pad that is too aggressive for street use (leading to noise or rotor wear) or too mild for performance applications (compromising safety). Hawk updates its chart regularly to reflect product improvements and new releases, ensuring it remains a reliable source of current information. In essence, the chart bridges the gap between technical engineering data and practical consumer use, making it an indispensable tool for DIY enthusiasts, mechanics, and racing teams alike.
Key Components of the Hawk Brake Pad Chart Explained
The Hawk brake pad chart is organized around several key parameters that define performance. Understanding each component is crucial for effective use. Here, we will describe these elements in detail, using bold terms for emphasis.
1. Friction Coefficient: This is a measure of how effectively the brake pad generates friction against the rotor. It is represented as a number (e.g., 0.45) or a rating scale (like "high" or "medium"). Hawk's chart typically lists friction coefficients across different temperature ranges. A higher friction coefficient means more stopping power, but it can also increase rotor wear and noise. The chart shows values at cold, operating, and hot temperatures, indicating how consistent the pad performs under various conditions. For example, a pad with a high and stable friction coefficient across temperatures is ideal for performance driving, while one with a moderate coefficient might be better for street use to ensure smooth engagement.
2. Operating Temperature Range: Brake pads are designed to work optimally within specific temperature intervals. Hawk's chart specifies the minimum and maximum effective temperatures for each pad series. This is critical because pads that operate outside their intended range can fade (lose effectiveness) or wear prematurely. The chart divides temperatures into categories such as street (low to moderate heat) and race (very high heat). By matching the temperature range to your driving style—like city driving with occasional stops versus track laps with heavy braking—you can select a pad that maintains performance without overheating.
3. Noise and Dust Levels: These are practical considerations for everyday usability. The chart rates noise (squeal) and dust production on a scale from low to high. Pads with aggressive compounds often generate more noise and dust, which might be acceptable for racing but undesirable for street vehicles. Hawk provides honest ratings, so you can choose a pad that balances performance with comfort. For instance, ceramic-based pads typically score low on noise and dust, making them popular for daily drivers.
4. Rotor Compatibility: This indicates whether the pad is suitable for use with standard street rotors, slotted rotors, or drilled rotors. Some high-performance pads require specific rotor types to function correctly and avoid damage. The chart notes compatibility to prevent mismatches that could lead to rotor cracking or uneven wear. Always check this section to ensure your rotors are appropriate for the pad you select.
5. Application Category: Hawk categorizes pads into groups such as street, performance street, track/competition, and race-only. The chart clearly labels each pad series with its primary application. This is a quick way to narrow down choices based on your vehicle's use. For example, pads marked for "street" are engineered for quiet operation and low dust, while "track" pads prioritize high-temperature stability and friction.
6. Bed-In Procedure and Wear Characteristics: While not always graphical, the chart often includes notes on bed-in requirements (the process to season pads for optimal performance) and expected wear rates. This information helps you understand maintenance needs and longevity. Performance pads might require more meticulous bed-in but offer longer life under harsh conditions.
By studying these components on the chart, you can make an informed comparison. For instance, if you need a pad for a sports car used on weekends, you might look for a high friction coefficient, a broad operating temperature range, moderate noise, and an application category of "performance street." The chart allows you to cross-reference these factors easily.
How to Read and Interpret the Hawk Brake Pad Chart Step by Step
Reading the Hawk brake pad chart involves a systematic approach to extract relevant information. Follow these steps to interpret it accurately for your needs.
Step 1: Identify Your Driving Application. Start by determining how you use your vehicle.

Refer to the chart's application section to see which pad series align with your use case. For example, if you drive a family SUV, focus on pads labeled for street use with low noise and dust. If you have a modified car for track events, look at track-oriented pads.
Step 2: Examine Friction and Temperature Data. Locate the friction coefficient and operating temperature range for the pads that match your application. Compare these values across similar pads. A higher friction coefficient is not always better; it must suit your vehicle's weight and braking system. Similarly, ensure the temperature range covers the heat generated during your driving. For street use, a range of 100°F to 800°F might suffice, while racing pads may extend to 1500°F.
Step 3: Assess Practical Factors. Check noise and dust ratings. If you prioritize a quiet cabin and clean wheels, select pads with low ratings. Also, review rotor compatibility to confirm they work with your existing rotors. If you plan to upgrade rotors, the chart can guide compatible pairings.
Step 4: Consider Long-Term Usability. Look at wear characteristics and bed-in procedures. Pads with longer life and simpler bed-in are convenient for street vehicles. Performance pads might require more frequent changes but deliver superior braking under stress.
Step 5: Cross-Reference with Vehicle Specifications. While the chart provides general data, always verify that the pad is available for your specific vehicle make, model, and year. Hawk offers fitment guides separate from the chart; use them in conjunction to ensure compatibility.
Step 6: Make a Balanced Decision. Weigh all factors—performance, comfort, durability, and cost. The chart helps visualize trade-offs; for instance, a pad with high friction might have high dust. Choose based on what matters most for your situation.
To illustrate, suppose you own a sedan for daily driving and occasional highway trips. You might use the chart to find pads with a moderate friction coefficient (around 0.40), a temperature range of 200°F to 600°F, low noise and dust ratings, and street application. This ensures reliable braking without compromises for comfort. By following these steps, you can navigate the chart efficiently and avoid selection errors.

Remember that environmental factors like climate can affect performance; for hot regions, choose pads with a higher temperature range as per the chart. By applying the chart systematically, you can optimize braking for your specific situation.
Installation and Maintenance Tips Based on Chart Information
The Hawk brake pad chart not only aids selection but also informs installation and maintenance practices. Here are key tips derived from chart data.
1. Bed-In Procedures: The chart often references bed-in requirements. Bed-in is the process of transferring pad material onto the rotor to ensure even friction and prevent noise. For performance pads like HP Plus or DTC series, the chart implies a more rigorous bed-in due to their high friction compounds. Typically, this involves a series of moderate to hard stops from specific speeds, followed by cooling periods. Follow Hawk's recommended bed-in steps to achieve optimal performance as indicated by the chart's friction stability.
2. Rotor Preparation: Based on rotor compatibility notes on the chart, prepare your rotors accordingly. For new pads, especially performance ones, ensure rotors are clean and free of old pad material. If the chart specifies use with slotted rotors, avoid using drilled rotors to prevent cracking. Resurface rotors if needed to match the pad's surface requirements.
3. Monitoring Temperature and Wear: The chart's operating temperature range guides usage. Avoid exceeding the maximum temperature to prevent fade and damage. For street pads, this is less critical, but for track pads, use brake cooling ducts if necessary. Also, check wear rates indicated on the chart; performance pads may wear faster under hard use. Inspect pads regularly and replace them before they reach minimum thickness.
4. Noise and Dust Management: If you selected pads with moderate noise or dust per the chart, take preventive measures. Use brake lubricant on caliper contact points to reduce squeal. Clean wheels frequently to manage dust buildup. The chart helps set expectations, so you are not surprised by these factors.
5. Compatibility Checks: Always verify that installed pads match the chart's compatibility with other components like calipers and brake fluid. For high-temperature pads, consider upgrading to high-temperature brake fluid to handle the heat as suggested by the chart's data.
By aligning maintenance with chart insights, you extend pad life and maintain braking efficiency. For instance, if the chart shows a pad has a high wear rate, plan for more frequent inspections. This proactive approach ensures safety and performance.
Common Misconceptions and Errors When Using the Hawk Brake Pad Chart
Even with a detailed chart, mistakes can occur. Here are common pitfalls and how to avoid them.
1. Overlooking Temperature Range: Users often focus only on friction coefficient and ignore temperature. This can lead to selecting a pad that fades under their driving conditions. Always match the temperature range to your typical braking heat. For example, using a street pad with a low maximum temperature on track days will cause failure.
2. Ignoring Noise and Dust Ratings: Some prioritize performance and dismiss noise/dust, resulting in uncomfortable daily driving. The chart provides these ratings for a reason; consider them based on your tolerance. A high-performance pad with high noise might be fine for racing but annoying on the street.
3. Misinterpreting Application Categories: Assuming all "performance" pads are the same can cause issues. The chart distinguishes between performance street and race-only pads. Using a race pad on the street is dangerous because it may not generate enough friction at low temperatures, as shown in the chart's cold friction data.
4. Neglecting Bed-In Requirements: Skipping or improper bed-in can lead to reduced effectiveness and noise. The chart often implies bed-in needs; follow them strictly to achieve the rated performance.
5. Failing to Check Compatibility: The chart might not list every vehicle fitment. Always use it alongside Hawk's application guide to ensure the pad fits your specific model. Installing incompatible pads can cause safety hazards.
6. Not Considering Driving Style Changes: If your driving habits evolve—like starting track events—revisit the chart to reassess pad choice. The chart is a dynamic tool; update your selection as needs change.
By being aware of these errors, you can use the chart more effectively. For instance, if you plan to tow occasionally, choose a pad with a higher temperature range than usual, even for street use, to account for extra heat.
