Aston Martin DB9 Brake Pads: Your Ultimate Guide

When it comes to maintaining a prestigious vehicle like the Aston Martin DB9, every component, no matter how small, plays a crucial role in its performance and safety. One question that frequently arises among owners, especially those new to the marque, is whether the Aston Martin DB9 uses conventional brake pads. The short answer is a resounding yes, and what's more, these aren't just any brake pads. The braking system on the DB9, supplied by the renowned Italian manufacturer Brembo, is a testament to high-performance engineering, surprisingly shared with a host of other iconic sports cars of its era. This shared heritage means that unlike many bespoke Aston Martin parts, there's a wider array of aftermarket brake pad options available, offering owners choices that balance performance, cost, and convenience. This comprehensive guide will delve into the world of DB9 brake pads, helping you make an informed decision when it's time for a service.

Understanding Your DB9's Braking System

The Aston Martin DB9, from its initial release in 2004 through to 2016, primarily featured a robust braking system designed and manufactured by Brembo. This wasn't a unique setup exclusively for Aston Martin; these very same high-calibre Brembo calipers and rotors found their way onto other performance titans such as the Chevrolet Corvette ZR1, Dodge Viper, Ford GT, Camaro SS, and even the Subaru STI, among others. This widespread adoption in the 'cream of the crop' performance cars of the era speaks volumes about the system's effectiveness and reliability. This high-volume usage, compared to Aston Martin's more limited production numbers, is precisely why the aftermarket for DB9 brake pads is more vibrant than for many other Aston parts.

It's crucial to note that this article specifically discusses the steel Brembo brake system. Aston Martin did offer an optional upgrade to mighty Carbon Ceramic Matrix (CCM) brakes, which are an entirely different beast altogether, with their own unique pads and maintenance procedures. These CCM brakes are not covered here. Furthermore, this discussion excludes the separate handbrake pads, which require far less frequent attention and are not part of the regular braking system's wear and tear cycle.

The Importance of Brake Pad Choice

Choosing the right brake pads for your DB9 isn't just about stopping power; it's about balancing performance characteristics with your driving habits and aesthetic preferences. Factors like brake dust, noise (squeal), longevity, and initial bite all vary significantly between different pad compounds. Over my years of owning a 2005 DB9 Coupe fitted with the standard 4-piston calipers front and rear, I've had the opportunity to experiment with a few popular options. While my experience is limited to a handful of brands, I aim to provide a clear outline of what you can expect from each, helping you navigate your options when it's time for your next brake service.

Aston Martin OEM Brake Pads (Made by Pagid)

Despite the Brembo design of the overall brake system, the original equipment manufacturer (OEM) brake pads fitted to the Aston Martin DB9 were produced by Pagid, a highly respected name in automotive friction materials. Aston Martin then re-packages these pads under their own part numbers for distribution. These are the pads your DB9 would have left the factory with, and they represent the baseline for performance and characteristics.

My personal experience with the OEM Pagid pads was dominated by one overwhelming characteristic: they were terribly dusty. I recall spending considerable time detailing my wheels, only to drive a mere 1.6 miles through city traffic to work and arrive with enough brake dust to literally write my name on the rims. This constant battle with dust was a significant drawback for me, diminishing the pristine appearance of the car's wheels far too quickly.

However, it wasn't all negative. The upside of these OEM pads is their relatively 'soft' compound compared to many aftermarket alternatives. This softness contributes significantly to their quiet operation, making them far less prone to the dreaded brake squeal that can plague some performance pads. If silent braking performance is your absolute priority, and you don't mind the frequent wheel cleaning, the OEM pads are your best bet. Yet, this quiet performance comes at a considerable financial cost. A full set of front and rear OEM pads can run close to $800 USD, which for many, including myself, feels ridiculously expensive when compared to the cost of pads for even other performance vehicles.

For reference, the Aston Martin part number for the steel brake pads appears to cover DB9 models from 2004 through at least 2016, but it's always prudent to verify the exact part number for your specific vehicle before making a purchase. The official Aston Martin recommended bedding-in procedure for these Pagid pads is also a specific process, designed to optimise their performance and longevity.

Porterfield R4-S Brake Pads

My quest for a less dusty, more cost-effective solution began after a conversation at an Aston Martin Track Day back in 2014. Another owner introduced me to the Porterfield Enterprise brake pads, specifically the R4-S compound, touted for significantly less dust production at roughly half the price of the OEM pads. Porterfield is renowned in the racing community for producing high-performance brake components, and the R4-S is their 'Street Compound' – a slightly softer formulation derived from their racing pads, adapted for optimal performance on road cars like our Aston Martins.

After finishing off my decade-old OEM pads, I seized the opportunity to try the Porterfields. I fitted a new set to both the front and rear axles, along with new rotors, and the results were genuinely impressive. The reduction in brake dust was dramatic – a mere fraction of what the OEM pads produced. This alone was a massive improvement for daily usability and maintaining the car's appearance. Coupled with the substantial cost savings (around $350 USD for a complete set of front and rear pads at the time), the Porterfield R4-S pads quickly became my preferred choice.

The Porterfield pads also have their own unique bedding-in procedure, which is vital to follow for optimal performance and to prevent issues like premature wear or noise. This attention to detail during installation is key to unlocking their full potential on the road.

EBC Red Stuff Brake Pads

After approximately 20,000 miles and four years of excellent service from my first set of Porterfield pads, I decided to explore other options available on the market. Online forums often featured discussions about EBC Red Stuff brake pads, another brand with a strong racing heritage. EBC categorises their pads by colour, with 'Red Stuff' signifying their performance street pad, while 'Yellow Stuff' indicates a harder, more track-focused compound. For those who appreciate products manufactured closer to home, it's worth noting that all EBC pads are made in the UK.

A major draw of the EBC Red Stuff pads was their accessibility and price point. I found them readily available online, with prices nearly half again lower than the Porterfields, bringing them into the realm of 'regular' car brake pad prices – around $200 USD for a full set of front and rears. This affordability was compelling, and I enthusiastically ordered a set.

Upon fitting the new EBC Red Stuff pads and accompanying rotors, I made a big mistake. Instead of researching the specific bedding-in procedure for EBC pads, I instinctively followed the Aston Martin OEM procedure, which is designed for Pagid pads. This, as I later learned, was 100% the opposite of EBC's recommended process. The consequence was severe and immediate: I believe I glazed my new rotors and pads, resulting in ferocious squealing. The noise was so pervasive and irritating that I eventually gave up after about a month and reverted to a fresh set of Porterfield pads.

While I initially wrote a scathing review of the EBC Red Stuff pads based on that experience, I now acknowledge that the fault likely lay with my incorrect bedding-in procedure, rather than the pads themselves. To be fair to EBC, I truly believe they deserve another chance, this time with the correct bedding-in. If you are considering or have used EBC Red Stuff pads, particularly with the correct procedure, your feedback would be invaluable to the community.

Comparative Overview of Brake Pads

To help summarise the characteristics of the three main brake pad types discussed, here's a comparative table:

Other Brands and Further Opinions

While my direct experience is limited to the brands mentioned, it's worth noting that other reputable manufacturers also produce brake pads suitable for the Aston Martin DB9. These include Hawk HPS, EBC Yellow Stuff (a harder compound than Red Stuff), and Stoptech. If you've had first-hand experience with any of these or other brands on your DB9, sharing your insights would greatly benefit the community.

For those seeking additional perspectives, Richard Seidlitz, who runs Redpant.lol, has also penned his thoughts on brake pads for the Aston Martin Vantage. Given that the Vantage often shares the same Brembo braking system as the DB9, his insights are highly relevant and worth exploring. His blog is also a useful resource for purchasing pads, rotors, and other components, particularly for those in the USA.

The Critical Art of Bedding-In Brake Pads

The importance of properly bedding-in new brake pads and rotors cannot be overstated. This process, often overlooked or misunderstood, is absolutely crucial for optimising braking performance, reducing noise, and extending the life of your brake components. Bedding-in involves a specific series of controlled stops that gradually heat the pads and rotors, allowing a thin, even layer of friction material to transfer from the pads onto the rotor surface. This transfer layer is essential for consistent braking and preventing issues like judder and squeal.

As highlighted by my experience with the EBC Red Stuff pads, different pad manufacturers often have distinct bedding-in procedures tailored to their specific compounds. Following the correct procedure for your chosen pads is paramount. Failing to do so can lead to glazing of the pads and rotors, resulting in reduced braking effectiveness and, as I discovered, persistent and infuriating squealing. Always consult the manufacturer's instructions or a reliable guide specific to your brake pad model before driving enthusiastically on new brakes.

What About Changing Your Brake Rotors Too?

When you're replacing your brake pads, it's a natural extension to consider the condition of your brake rotors. Rotors, like pads, are wear items and their condition directly impacts braking performance and safety. Pitting, scoring, warping, or simply falling below minimum thickness specifications all indicate a need for replacement. While this article focuses primarily on brake pads, it's important to remember that a complete braking system overhaul often involves new rotors to ensure optimal performance and longevity of your new pads. Comprehensive research and a detailed understanding of rotor options, including material and design, are just as important as choosing the right pads.

Frequently Asked Questions About Aston Martin DB9 Brake Pads

Q1: How often should I replace my DB9 brake pads?

A1: The lifespan of your brake pads varies significantly based on your driving style, the type of pads installed, and whether you're primarily driving in city traffic or on open motorways. Aggressive driving, frequent hard braking, and stop-and-go city conditions will wear pads down faster. Generally, you should inspect your pads at every service interval, typically annually or every 10,000 miles (whichever comes first). Some owners might find their pads last 15,000-20,000 miles, while others might need replacement sooner. Look for warning signs like reduced braking performance, grinding noises, or a noticeable decrease in pad material thickness.

Q2: Will aftermarket brake pads void my Aston Martin warranty?

A2: Generally, using aftermarket parts like brake pads will not automatically void your entire vehicle warranty. However, if a failure in your braking system can be directly attributed to the aftermarket pads (e.g., they caused damage to the calipers or rotors due to an incompatible compound or improper installation), the warranty claim for that specific component or related damage might be denied. It's always best to use reputable brands and ensure professional installation to minimise any potential issues.

Q3: Why do my new brake pads squeal?

A3: Brake squeal is a common complaint, especially with performance-oriented pads. The primary reasons include improper bedding-in (as experienced with the EBC pads), incorrect installation (e.g., not using anti-squeal shims or paste), vibration of the pads within the caliper, or simply the inherent characteristics of the pad compound. Some high-performance compounds are simply noisier by nature due to their material composition and higher friction levels. Ensuring correct installation, meticulous cleaning of components, and following the specific bedding-in procedure for your chosen pads are the best ways to mitigate squeal.

Q4: Are carbon ceramic brakes a worthwhile upgrade for a DB9?

A4: Carbon ceramic brakes offer significant advantages in terms of weight reduction (improving unsprung mass), fade resistance under extreme use (like track driving), and longevity of the rotors. However, they are vastly more expensive to replace, can be noisier at low speeds, and may not offer significant benefits for purely road-going cars where their full performance potential isn't exploited. For a daily driver, the steel Brembo system with quality aftermarket pads generally provides more than adequate stopping power at a much lower running cost.

Q5: Can I mix and match different brake pad brands front and rear?

A5: While technically possible, it is generally not recommended to mix different brake pad compounds between the front and rear axles. Brake systems are designed to have a balanced front-to-rear bias, and using different compounds can alter this balance, potentially leading to unpredictable braking behaviour, reduced stability under heavy braking, or uneven wear. For optimal performance and safety, it's always best to use the same brand and compound of brake pads on both axles.

In conclusion, the Aston Martin DB9 does indeed utilise conventional brake pads, and thanks to the widely adopted Brembo braking system, owners have a surprising array of aftermarket options. From the high-dust, quiet OEM Pagid pads to the low-dust, cost-effective Porterfield R4-S, and the highly affordable EBC Red Stuff (with proper bedding-in), there's a solution to suit various preferences and budgets. Understanding the characteristics of each, and crucially, adhering to the correct installation and bedding-in procedures, will ensure your DB9 continues to deliver exhilarating performance with absolute confidence in its stopping power. Happy motoring, and safe braking!
