Choosing the Right Aftermarket Brake Pads for Your 2003-2008 INFINITI FX45
Get the stopping power your performance SUV deserves by understanding your aftermarket brake pad options.
- Ceramic brake pads are a popular aftermarket upgrade for the FX45, offering low dust and quiet operation.
- OEM pads are known to be effective but can cause excessive brake dust; many owners prefer aftermarket alternatives like Akebono for cleaner wheels.
- Always consider replacing rotors with pads for the best performance and to avoid issues like brake judder.
- Properly 'bedding-in' new brake pads is a critical step to ensure quiet, powerful, and smooth braking.
Symptoms of Failing Brake Pads
Your FX45 will give you clear signs when the brake pads are nearing the end of their life. The most common symptom is a high-pitched squealing noise when you apply the brakes. This sound comes from a small metal tab called a wear indicator, which is designed to contact the rotor when the pad material gets too thin. If you ignore the squeal, it will eventually turn into a harsh grinding noise. This means the pads are completely worn out, and metal is grinding against metal, which can quickly damage your brake rotors and lead to more expensive repairs. Other signs include a vibrating or pulsating brake pedal (which can also indicate warped rotors), the vehicle pulling to one side when braking, or simply taking longer to stop than usual.
Choosing the Right Aftermarket Brake Pads for Your FX45
The original equipment (OEM) brake pads on the FX45 are known to perform well but can also produce a lot of brake dust and may be prone to squeaking. Many owners choose aftermarket pads to get different performance characteristics, such as lower dust, less noise, or increased stopping power. For the FX45, ceramic brake pads are a very popular aftermarket choice because they offer a great balance of performance, low noise, and significantly less dust than OEM pads.
Brand Tiers for Aftermarket Pads
With so many brands available, it helps to group them into categories based on owner feedback and intended use.
- Premium & OEM-Equivalent: These brands are known for quality that meets or exceeds original factory specs. They are an excellent choice for daily driving, offering quiet operation and low dust. Brands like Akebono are highly recommended by FX owners for their clean, quiet performance, similar to or better than OEM. Brembo, Bosch, and Advics also fall into this category, providing reliable, consistent stopping power.
- Performance & Track-Focused: If you use your FX45 for more aggressive driving or want a more immediate bite from your brakes, these brands are for you. Hawk Performance and EBC Brakes are popular choices. Be aware that performance pads like these often create more dust and may be noisier than ceramic daily-driver pads. PowerStop offers "Track Day" specific pads for those who participate in high-performance driving events, but these are not recommended for street use.
- Daily Driver & Value: These brands offer a solid combination of performance and price for everyday use. They are a dependable alternative to premium brands. Look for names like Centric, Raybestos, and Wagner Brakes. They provide safe, reliable braking for normal commuting and driving conditions.
- Economy: For those on a tight budget, economy brands provide a functional and safe, though basic, option. Brands in this tier include Dynamic Friction and Pronto. While they meet safety standards, they may not offer the same longevity, low noise, or low dust characteristics of higher-priced options.
Pro Tip: Bedding In Your New Brakes
Most new brake pads require a "bed-in" or "break-in" procedure. This involves a series of controlled stops to properly transfer a layer of friction material from the pads to the rotors. This step is crucial for achieving smooth, quiet, and powerful braking for the life of the pads. Always follow the manufacturer's specific instructions for bedding in your new brake pads.
Known Issues, Recalls, and TSBs
While there are no specific recalls for the brake pads themselves on the 2003-2008 FX45, there was a recall concerning front brake caliper mounting bolts that may not have been properly tightened on some vehicles. This could cause the caliper to loosen or separate, leading to brake failure. There was also a Technical Service Bulletin (TSB) related to brake judder (shaking) on some Infiniti models with four-piston calipers, which pointed to the hardware pins rather than warped rotors as a potential cause. When replacing your pads, it's always a good idea to inspect the calipers and all related hardware.

Frequently Asked Questions (FAQ)
Should I replace my brake rotors at the same time as the pads?
It is highly recommended. While not always strictly necessary, installing new pads on old, worn, or warped rotors can lead to noise, vibration, and reduced brake performance. For best results and to ensure a proper bed-in process, replacing pads and rotors together is the best practice.
What's the difference between ceramic and semi-metallic pads?
Ceramic pads are made from dense ceramic material and are known for being very quiet, producing very little dust, and being gentle on rotors. Semi-metallic pads contain metal fibers and offer excellent heat dissipation and stopping power, but they are often noisier, produce more dust, and can wear rotors more quickly. For most FX45 owners, ceramic pads offer the best combination of features for daily driving.
Why are my new brakes squeaking?
New brakes can squeak for several reasons. It could be due to debris caught between the pad and rotor, a lack of proper lubrication on the caliper pins or pad contact points, or an improper bed-in procedure. Often, the noise will go away after the pads are fully bedded in. If it persists, the installation should be re-checked.
Is it difficult to replace brake pads on an FX45 myself?
For someone with basic mechanical skills and the right tools, replacing the brake pads and rotors on an FX45 is a manageable DIY job. There are numerous online guides and videos available. However, brakes are a critical safety system, so if you have any doubts, it is always best to have the work performed by a qualified professional.
