A Practical Guide to the 2018-2025 Audi A5 Disc Brake Hardware Kit
Eliminate brake noise and ensure proper function by understanding this small but crucial brake system component.
- Always replace the disc brake hardware kit when you replace your brake pads to prevent noise and ensure even wear.
- Symptoms of bad hardware include squealing, rattling, and uneven pad wear.
- Quality aftermarket brands like Dynamic Friction and Raybestos offer a cost-effective alternative to expensive OEM parts.
- Verify the correct kit for your A5's specific brake system (front/rear, caliper type) before purchasing.
Is Your Audi A5 Making Brake Noises? It Could Be The Hardware.
When you press the brake pedal in your 2018-2025 Audi A5, you expect smooth, quiet stopping. If you hear squealing, grinding, or rattling, your first thought might be worn-out brake pads. While that's often true, the small metal clips and springs that hold those pads in place—the disc brake hardware—are just as important and often overlooked. This hardware can corrode and lose its tension over time, especially in areas with harsh winters and road salt. When this happens, it can lead to a variety of braking problems.
Always Replace Hardware With New Pads
It is standard practice and highly recommended to replace the disc brake hardware kit every time you replace your brake pads and rotors. The old clips have been exposed to thousands of heat cycles and can lose their spring tension. Reusing them can lead to noise, premature pad wear, and reduced braking performance right after a brake job. Given the low cost of aftermarket kits, there is no reason to skip this step.
Symptoms of Failing Brake Hardware
Bad brake hardware can cause symptoms that are often mistaken for bad pads or rotors:
- Squealing or Chirping: Especially during light braking, this can happen when pads vibrate because the clips are no longer holding them tightly.
- Rattling or Clicking: A loose, metallic rattle when driving over bumps can be a sign that the hardware is not holding the pads securely in the caliper bracket.
- Uneven Brake Pad Wear: If hardware is seized or bent, it can cause a brake pad to stick, leading to one pad wearing out much faster than the other.
- Brakes Dragging: Corroded or weak hardware can prevent the pads from retracting properly from the rotor, causing constant friction, excess heat, and poor fuel economy.
Choosing The Right Aftermarket Hardware
For a part like a brake hardware kit, you don't necessarily need to pay the high price for an OEM (Original Equipment Manufacturer) part from an Audi dealer. Quality aftermarket brands offer reliable products that meet or exceed OEM specifications for a fraction of the cost. The key is choosing a reputable brand.
Pro Tip: Many aftermarket brake pad kits for your A5 will include a new hardware kit in the box. Check the contents before buying a separate kit.
- Dynamic Friction (DFC): Often considered a reliable OE-quality replacement brand. Their hardware kits are known to be a good value, providing consistent performance for daily driving.
- Raybestos: A long-established brand in the brake industry. While some forum users have noted concerns about declining quality on certain product lines, their brake components are generally considered a dependable aftermarket option.
Known Issues: Brake Noise TSB
Audi has issued a general Technical Service Bulletin (TSB 46 22 34 2034181/22) for brake noise on models from 2008-2023. It notes that squealing and grinding can have many causes, including contamination or improper bedding-in of new pads. One of the suggested service actions is to clean and lubricate the caliper guide pins, which are often included in more comprehensive hardware kits. This highlights the importance of the hardware system in preventing noise.

Frequently Asked Questions
Do I really need to replace my brake hardware?
Yes. It is a critical safety and performance step. Old hardware loses tension from heat and can be corroded, leading to noise and uneven wear on your brand new pads and rotors. For the low cost, it is essential maintenance.
My brakes started squeaking right after I changed my pads. What's wrong?
This can be caused by several things. The new pads may need to be "bedded-in" to the rotors. However, it's also a classic symptom of reusing old hardware or improper installation. The clips may not be providing the correct tension, causing high-frequency vibration (squeal). Ensure anti-squeal paste was used correctly on the pad contact points with the new hardware.
Is an aftermarket hardware kit as good as the one from Audi?
For a simple mechanical part like this, a quality aftermarket kit from a brand like Dynamic Friction or Raybestos is perfectly acceptable and offers great value. They are designed to meet original equipment specifications. The significant cost savings over OEM parts can be put toward other maintenance items.
Does this hardware fit all 2018-2025 Audi A5 models?
Mostly, but be careful. The Audi A5 can have different brake caliper options (e.g., 1-piston or 4-piston calipers, different rotor sizes). Always verify the fitment for your specific A5 trim (Sportback, Coupe, etc.) and brake package before ordering. Some kits are for the front wheels and some are for the rear.
