Hawk HP+ vs OE Brake Pads: A Real-World Look

When it comes to replacing your car's brake pads, the temptation to upgrade from the original equipment (OE) manufacturer's offerings is strong. Many drivers seek improved stopping power, better feel, or simply a more performance-oriented experience. Among the popular aftermarket choices, Hawk Performance pads, particularly the HP Plus compound, often feature in discussions. However, the question remains: are Hawk HP+ pads genuinely a superior choice over standard OE pads? This article aims to provide a comprehensive comparison, drawing on real-world experiences and highlighting the key differences you can expect.

Understanding Brake Pad Compounds

Before delving into the comparison, it's essential to understand the fundamental differences between various brake pad compounds. OE pads are typically designed with a focus on a balance of longevity, low noise, minimal dust, and acceptable braking performance for everyday driving. They are engineered to meet the manufacturer's specifications and often utilise ceramic or semi-metallic formulations that prioritise comfort and durability.

Aftermarket performance pads, such as those from Hawk, often adopt different material compositions to achieve specific goals. The Hawk HP Plus compound, for instance, is a high-performance friction material formulated for increased stopping power, particularly under demanding conditions. This usually involves a more aggressive friction material, often a more aggressive semi-metallic or even an organic compound with higher metallic content, designed to generate more heat and bite. However, this enhanced performance often comes with trade-offs.

Performance: The Stopping Power Debate

The primary reason many consider upgrading to performance pads like the Hawk HP Plus is the promise of enhanced stopping power. While it's true that performance compounds can offer a more immediate and forceful initial bite, the perceived improvement over OE pads in everyday street driving can be subjective and dependent on the specific OE pads your vehicle is equipped with.

In many instances, drivers have found that the Hawk HP Plus, while a step up from very basic OE pads, doesn't always translate into a dramatically noticeable improvement for typical street use. The difference might be more apparent during spirited driving or emergency braking situations where the pads are pushed closer to their thermal limits. For daily commuting, traffic, and moderate braking, the enhanced performance might not be as significant as anticipated, and the benefits might be overshadowed by other factors.

The Downsides: Dust, Noise, and Rotor Wear

This is where the comparison often becomes stark. While performance pads excel in certain areas, they frequently introduce compromises in others. The Hawk HP Plus compound, in particular, is known for a few significant drawbacks:

Brake Dust: A Grimy Reality

Performance pads, especially those with a higher metallic content, tend to shed more friction material during use. This translates directly into a considerably higher volume of brake dust. While OE pads can leave some dust, the HP Plus compound is notorious for producing a significant amount of dark, gritty dust that adheres tenaciously to your wheels. This means more frequent and intensive cleaning is required to keep your vehicle looking its best. The aesthetic impact of this increased dust can be a major deterrent for many drivers.

Noise: The Soundtrack of Performance

Another common characteristic of performance brake pads is increased noise. The Hawk HP Plus is known to be noisier than many OE compounds. This can manifest as:

• Low-speed squeal: A high-pitched squeal that is often more noticeable at lower speeds, especially during light braking.
• Groaning or grinding sounds: Under heavier braking, or when the pads are cold, you might experience more pronounced audible feedback.

While some performance enthusiasts might tolerate or even appreciate this auditory feedback as a sign of the brakes working hard, for many everyday drivers, the increased noise can be an unwelcome intrusion, detracting from the overall driving experience and comfort of the vehicle.

Rotor Wear: The Hidden Cost

Perhaps the most critical consideration when comparing performance pads to OE is the impact on brake rotor wear. More aggressive friction materials, like those found in the Hawk HP Plus, are designed to create higher friction coefficients. To achieve this, they often contain harder abrasives or materials that are inherently more abrasive.

This aggressive nature means that the pads wear down the rotor surface at a significantly faster rate compared to milder OE compounds. In street driving conditions, where brakes are applied frequently but not always at extreme temperatures, this accelerated wear can lead to rotors needing replacement much sooner than they would with OE pads. This is a substantial long-term cost that needs to be factored into the decision. The phrase "truly horrible rotor wear rates" has been used by drivers to describe the experience with these pads on street-driven vehicles.

Comparative Table: Hawk HP+ vs. OE Pads

To summarise the key differences, consider the following table:

Who Should Consider Hawk HP+ Pads?

Given the trade-offs, the Hawk HP Plus compound is typically best suited for drivers who:

• Engage in spirited driving on public roads where increased stopping power is a priority.
• Participate in occasional track days or autocross events where brake performance under sustained heat is crucial.
• Are willing to accept the increased dust, noise, and accelerated rotor wear in exchange for enhanced braking.
• Prioritise a more aggressive pedal feel and initial bite.

When OE Pads Might Be the Better Choice

For the vast majority of car owners, sticking with or replacing with equivalent OE-quality pads is often the more sensible choice. OE pads are generally the best option if you:

• Value a quiet and clean driving experience.
• Want to maximise the lifespan of your brake rotors.
• Are primarily concerned with reliable stopping power for everyday commuting and general driving.
• Are on a tighter budget and want to avoid premature replacement costs for rotors.
• Do not engage in high-performance driving situations.

Frequently Asked Questions (FAQs)

Q1: Will Hawk HP+ pads make my car stop significantly faster in an emergency?

While they can offer a more aggressive initial bite and potentially better performance at higher temperatures, the overall stopping distance in a typical emergency stop on the street might not be drastically different from good quality OE pads, unless the OE pads are worn or of very low quality. The benefits are more pronounced when the braking system is under sustained load.

Q2: How often will I need to clean my wheels if I use Hawk HP+ pads?

You will likely need to clean your wheels much more frequently, possibly after every significant drive, to manage the high volume of brake dust. If you value clean wheels, this is a major consideration.

Q3: Can I use Hawk HP+ pads for daily commuting?

Yes, you can use them for daily commuting, but you must be prepared for the associated noise, dust, and accelerated rotor wear. For many, the compromises outweigh the benefits for this type of use.

Q4: How much sooner will my rotors wear out with HP+ pads?

It's difficult to give an exact figure as it depends on driving style, vehicle weight, and the specific OE rotors. However, drivers often report needing rotor replacements twice as frequently, or even more, when using aggressive compounds like the HP Plus for street driving compared to OE pads.

Q5: Are there quieter or cleaner performance pads available?

Yes, Hawk offers other compounds like the HPS (High Performance Street) or HPS 5.0, which are generally designed to be quieter and produce less dust than the HP Plus, while still offering some performance improvement over OE. If you want an upgrade but are concerned about the drawbacks of the HP Plus, exploring these other options would be advisable.

Conclusion

In summary, the decision between Hawk HP+ pads and OE pads is not a straightforward 'better or worse' scenario. The Hawk HP Plus offers a tangible increase in braking performance, particularly under more demanding conditions. However, this comes at a significant cost in terms of increased brake dust, noticeable noise, and crucially, a much faster rate of brake rotor wear. For the average driver focused on comfort, cleanliness, and long-term cost-effectiveness, OE or high-quality OE-equivalent pads will almost certainly be the superior choice. If you are a performance-oriented driver who can tolerate the compromises and understands the added wear and maintenance, then the HP Plus might be a worthy consideration, but thorough research into alternatives that might better suit your specific needs is always recommended.
