A Guide to Disc Brake Hardware for the 2005-2012 Audi A6 Quattro
Don't let worn-out clips and springs ruin your brake job; here's what you need to know for your C6 A6.
- Always replace the disc brake hardware kit when changing brake pads to prevent noise and uneven wear.
- A rattling noise from the wheels that vanishes when braking is a classic sign of worn hardware on the A6.
- For rear brake jobs, you must use a scan tool to retract the Electronic Parking Brake (EPB) before disassembly.
- Quality aftermarket brands like Raybestos, Centric, and Dynamic Friction offer reliable, cost-effective alternatives to OEM hardware.
Why You Shouldn't Re-Use Old Hardware
The brake hardware on your A6 Quattro is exposed to extreme heat, moisture, and road salt. This causes the metal clips and springs to lose their tension, rust, and wear out. Re-using old, weak hardware with new brake pads is a common mistake. It can lead to annoying brake noise, premature and uneven pad wear, and a spongy brake pedal. Since the hardware is already removed during a brake pad replacement, installing a new kit only adds a few minutes to the job and is a low-cost way to ensure your new brakes perform as they should.
A Critical Component for a Quiet Ride
A common complaint on the C6 A6 is a rattling or clunking noise from the wheels that disappears with light brake pressure. This is often caused by worn or missing anti-rattle clips, which are part of the hardware kit. Replacing the hardware is the correct fix for this specific issue.

You don't need to buy hardware from the Audi dealer to get a quality product. Aftermarket brands offer a range of options that meet or exceed original specifications. Here’s how they generally stack up for your A6:
- Premium Brands (Raybestos, Dynamic Friction, Centric): These brands often provide kits that are very close to the Original Equipment (OE) standard. They typically use high-quality materials with corrosion-resistant coatings. These are an excellent choice for ensuring a quiet, long-lasting repair.
- Standard Brands (Carlson, Dorman): These brands offer reliable, budget-friendly hardware kits that get the job done. While they may not have the same level of coating or finish as premium options, they are a perfectly acceptable replacement for a daily-driven vehicle.
Pro Tip: Clean and Lubricate
When installing your new hardware, make sure to thoroughly clean the caliper bracket where the clips sit. Use a wire brush to remove all rust and debris. Apply a thin layer of high-temperature brake lubricant to the points where the pads slide on the new hardware clips. This ensures smooth, quiet operation.
Estimated Costs for Disc Brake Hardware Kit
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Hardware Kit (per axle) | $6.69 - $40.95 |
| Shop Labor (as part of a full brake job) | $0 (Included in brake job labor) |
Note: Labor for hardware replacement is almost always included in the cost of a brake pad and rotor replacement. It is rarely, if ever, a standalone job.
Frequently Asked Questions (FAQ)
Do I really need to replace the hardware with every brake job?
Yes, it is highly recommended. The clips and springs are single-use parts that are critical for proper brake function. They are subjected to intense heat cycles which weakens them over time. For a small additional cost, a new hardware kit prevents future problems like noise and uneven wear.
Are there any recalls or TSBs for the brake hardware on my A6?
No, there are no specific recalls for the disc brake hardware on the 2005-2012 Audi A6 Quattro. However, Audi has issued Technical Service Bulletins (TSBs) like TSB 2034181 for general brake noise issues, which can be caused by worn hardware. Another TSB, 2022584, addresses brake pulsation, which can be related to improper hardware function.
Is installation different for the front and rear brakes?
Yes. While the hardware installation itself is similar, the rear brakes on the A6 Quattro feature an Electronic Parking Brake (EPB). You MUST use a diagnostic scan tool to retract the rear caliper pistons before starting the job. Attempting to push the pistons back manually will destroy the caliper motor. 🎬 Watch: How to service rear brakes with the electronic parking brake. The front brakes do not have this system.

OEM hardware is what Audi installed at the factory. High-quality aftermarket hardware from brands like Raybestos, Centric, or Dynamic Friction is designed to meet or exceed those OEM standards, often at a lower price. Brands like ATE and Textar are often the original suppliers to Audi, so their aftermarket parts are identical to OEM. For a component like brake hardware, a quality aftermarket kit is a smart and cost-effective choice.
