How do I perform a brake fluid flush on my Audi A6?

I recently purchased a used Audi A6 and want to make sure I properly maintain the brakes. Can you provide step-by-step instructions on how to perform a brake fluid flush for this specific car model?

First, gather all necessary tools and supplies such as a brake bleeder kit, new brake fluid, and a clean container to collect old fluid. Next, locate the brake fluid reservoir and remove the old fluid with a turkey baster. Then, attach the brake bleeder kit to the brake caliper and loosen the bleeder screw. Have a friend step on the brake pedal while you tighten the bleeder screw to force out old fluid. Repeat this process for each wheel. Finally, refill the reservoir with new fluid and bleed the system again until the fluid is clear.

It's important to perform a brake fluid flush every 2-3 years to ensure optimal brake performance and prevent damage to the brake system. If you're not comfortable doing it yourself, it's always best to take your car to a certified mechanic. They have the necessary tools and experience to do it correctly and safely.
