A Guide to Your 2015-2025 Audi A3 Disc Brake Hardware Kit
Eliminate annoying brake rattles and ensure proper brake function on your Audi A3 by replacing this often-overlooked kit.
- Always replace your disc brake hardware kit when changing brake pads to prevent noise and ensure even wear.
- A compatible electronic scan tool is MANDATORY to place the rear Electronic Parking Brake (EPB) in service mode before starting work on the rear brakes.
- Worn or corroded hardware is a very common source of rattling and squeaking noises on the Audi A3.
- For a small price increase, premium aftermarket kits with anti-corrosion coatings offer better longevity, especially in harsh climates.
Why This Small Kit is a Big Deal for Your Audi A3
When you think about a brake job, you usually think of pads and rotors. However, the disc brake hardware is the supporting cast that makes it all work. On a sensitive system like the one in your 2015-2025 Audi A3, old, rusty, or weak hardware is a primary cause of brake noise. Reusing old clips and springs can lead to rattling, squeaking, and uneven pad wear, even with brand new pads and rotors. Replacing the hardware kit during every brake service is a cheap and effective way to ensure a quiet, professional-quality result.
🎬 Watch this full walkthrough for replacing your A3 pads and rotors.Symptoms of Worn or Failing Brake Hardware
- Rattling or Clicking Noises: The most common symptom is a metallic rattle from the wheel area when driving over bumps, which may go away when you apply the brakes. 🎬 See how loose hardware causes that annoying rattling noise. This is often due to a weak or missing anti-rattle clip.
- Squealing or Scraping: While often a sign of worn pads, it can also be caused by hardware that isn't allowing the pads to retract properly, causing them to drag on the rotor.
- Uneven Brake Pad Wear: If guide pins are corroded and not lubricated, the caliper can't move freely. This causes the brake pads to wear at an angle, reducing their life and effectiveness.
- Brake Drag or Pulling: Sticking hardware can cause one or more pads to remain in contact with the rotor, leading to a pulling sensation, excess heat, and a burning smell.
CRITICAL: Servicing the Rear Brakes on Your A3
Your 2015-2025 Audi A3 is equipped with an Electronic Parking Brake (EPB). You cannot simply push the rear caliper pistons back to install new pads. You must use a compatible diagnostic scan tool (like VCDS or OBDEleven) to put the rear brakes into 'Service Mode' first. Failing to do this will permanently damage the electronic motors inside the brake calipers, resulting in a very expensive repair.

For a part like a hardware kit, aftermarket options provide excellent value. The key is to choose a reputable brand. Here’s how to think about your options:
- Standard Kits (Good): Brands like Dorman and the basic lines from Dynamic Friction or Raybestos offer kits that meet OEM specifications. They are a reliable and budget-friendly choice that will restore proper function. These are perfect for most daily driving situations.
- Coated/Premium Kits (Better): For a few dollars more, brands like Raybestos (Element3) and Dynamic Friction offer premium kits. These often feature coated hardware to resist rust and corrosion. This is an excellent upgrade for drivers in regions with heavy rain or snow where road salt is used. They may also be more comprehensive, including every possible clip and spring for your specific brake setup.
Pro Tip: When installing your new hardware, it's essential to clean all mounting surfaces on the caliper bracket thoroughly with a wire brush. Any rust or debris left behind can prevent the new clips from seating correctly, leading to the very noise you're trying to eliminate.

Frequently Asked Questions
Do I really need to replace the hardware with every brake job?
Yes, it is highly recommended. The metal clips lose their tension over thousands of heat cycles, and corrosion can prevent them from holding the pads correctly. For the low cost of a kit, it's the best insurance against noise and premature wear.
Can this kit fix my squealing brakes?
It can help, but it's not a guaranteed fix. Squealing is most often caused by the friction material of the brake pads themselves or a glazed rotor surface. However, if the squeal is from a pad vibrating, a new hardware kit with fresh anti-rattle clips can solve the problem.
What's the difference between front and rear hardware kits?
Front and rear brake systems on the Audi A3 are different sizes and designs, so they require specific hardware kits. They are not interchangeable. The rear kit's components are designed to work with the electronic parking brake caliper. Always ensure you are buying the correct kit for the axle you are servicing.
Are there any recalls for my A3's brake hardware?
There are no specific recalls for brake hardware on the 2015-2025 Audi A3. While earlier models had some issues and TSBs related to rattling from brake hardware, these have not led to a recall for the 8V generation (2015+). Always check for the latest recall information with your VIN at the NHTSA website.

Technical Specifications
Audi uses a Production Code (PR) system to identify specific brake components. You can find your vehicle's PR codes on the data sticker in the spare wheel well or your service manual. This is the most accurate way to ensure you purchase the correct hardware kit, as multiple brake options may exist for the same model year.
