2. Semi-Metallic Brake Pads
Semi-metallic brake pads are made from a mixture of metallic fibres (like steel, iron, or copper) and friction modifiers, bonded together.
Pros:
- Excellent Stopping Power: They offer a strong initial bite and excellent performance under heavy braking conditions.
- Good Heat Dissipation: The metallic content helps in dissipating heat effectively, reducing the risk of brake fade.
- Cost-Effective: Generally more affordable than ceramic pads.
Cons:
- More Dust: They tend to produce more brake dust, which is often darker and can be harder to clean.
- Noisier Operation: Can be noisier than ceramic pads, especially during the initial bedding-in period or under heavy use.
- Faster Rotor Wear: The metallic content can lead to slightly faster wear on your brake rotors compared to ceramic pads.
3. Organic Brake Pads (Less Common for A4)**
Also known as non-asbestos organic (NAO) pads, these are made from a blend of fibres like glass, rubber, and Kevlar, mixed with friction modifiers. While less common for performance-oriented vehicles like the Audi A4 as a primary choice, they are still a type of brake pad.
Pros:
- Quietest Operation: Typically the quietest option available.
- Gentle on Rotors: They cause the least amount of wear on brake rotors.
- Very Affordable: Usually the cheapest option.
Cons:
- Lower Performance: Offer less aggressive stopping power and are more prone to brake fade, especially under demanding conditions.
- Shorter Lifespan: They wear out faster than ceramic or semi-metallic pads.
- More Dust: Can still produce a noticeable amount of dust.
Choosing the Right Pads for Your 2017 Audi A4
The best brake pads for your 2017 Audi A4 depend on your driving habits:
- Daily Commuting: For everyday driving, city traffic, and occasional highway use, ceramic pads are often the ideal choice due to their quiet operation, low dust, and consistent performance.
- Spirited Driving/Performance: If you frequently engage in more dynamic driving, enjoy winding roads, or occasionally track your car, semi-metallic pads might offer the superior stopping power and heat resistance you need. Consider performance-oriented semi-metallic or even performance ceramic options if available.
- Budget-Conscious: If budget is a primary concern and your driving is very gentle, organic pads might be considered, but it's generally recommended to opt for ceramic or semi-metallic for the safety and longevity benefits they offer for a premium vehicle like the Audi A4.
Key Considerations Before Purchasing
Beyond the material type, here are some other factors to keep in mind:
- Brand Reputation: Stick with reputable brands known for quality and reliability. Some well-regarded brands for Audi brake pads include Brembo, Zimmermann, Textar, Bosch, and EBC.
- OE (Original Equipment) vs. Aftermarket: You can choose OE pads, which are designed to the exact specifications of your Audi A4 by the manufacturer. Aftermarket pads offer a range of options, from direct replacements to performance upgrades.
- Vehicle Specifications: Ensure the pads are specifically listed for the 2017 Audi A4, taking into account any specific trim levels or engine options that might affect brake size or type. Your A4 might have different brake systems depending on whether it's a front-wheel drive or quattro model, or if it has the optional S line package.
- Rotor Condition: When replacing brake pads, it's also essential to inspect your brake rotors. If they are significantly worn, grooved, or warped, they should be replaced or resurfaced along with the new pads for optimal braking performance and to prevent premature wear of the new pads.
Brake Pad Replacement: DIY vs. Professional
Replacing brake pads can be a DIY task for those with mechanical experience and the right tools. However, due to the critical nature of the braking system, many owners prefer to have this work done by a qualified mechanic.
DIY Advantages:
- Cost savings on labour.
- Satisfaction of performing your own maintenance.

- Need for accurate torque specifications for lug nuts and caliper bolts.
- Proper bedding-in procedure is crucial.
Professional Installation Advantages:
- Ensures correct installation and safety.
- Mechanics have the experience and tools to diagnose other potential brake issues.
- Peace of mind.
The Bedding-In Process
Once new brake pads (and potentially rotors) are installed, a proper bedding-in procedure is vital to ensure optimal performance and longevity. This process mates the new pad material to the rotor surface.
A common bedding-in procedure:
- Find a safe, open area with no traffic.
- Accelerate to a moderate speed (e.g., 30-40 mph).
- Apply the brakes moderately, slowing down to about 10 mph, but without coming to a complete stop.
- Repeat this process about 5-10 times.
- Follow this with a few harder stops from a higher speed (e.g., 50-60 mph) down to about 15 mph. Avoid slamming on the brakes.
- Finally, drive for several minutes without heavy braking to allow the brakes to cool.
Always follow the specific bedding-in instructions provided by the brake pad manufacturer.
