Introduction

If you own a C5 A6, you may have already experienced some brake fade or issues with the stock calipers. Upgrading to the 2003 Audi S8 caliper is a popular modification that can improve braking performance. In this tutorial, we will guide you through the process of converting the 2003 Audi S8 caliper onto a C5 A6.

What You Will Need

Before starting, you will need the following tools and materials:

2003 Audi S8 caliper
C5 A6 brake pads
Brake fluid
Brake line adapter fittings
Brake line flare tool
Wrenches and sockets
Jack and jack stands

Step-by-Step Guide

Step 1: Removing the Stock Caliper

Start by safely jacking up the car and removing the wheel. Then, remove the stock caliper by loosening and removing the two bolts that hold it in place. Be careful not to damage the brake line while removing the caliper.

Step 2: Preparing the S8 Caliper

Clean and inspect the 2003 Audi S8 caliper before installation. Make sure it is free of debris and rust. Also, ensure that the brake pads fit snugly into the caliper.

Step 3: Installing the S8 Caliper

Install the S8 caliper onto the brake rotor and secure it with the bolts. Use the brake line adapter fittings to connect the brake line to the new caliper. Use a brake line flare tool to create a flare on the end of the brake line if necessary.

Step 4: Bleeding the Brakes

Bleed the brakes to remove any air bubbles from the brake lines. Fill the brake fluid reservoir and pump the brakes until the fluid runs clear. Start from the furthest brake caliper and work your way towards the closest.

Step 5: Test Drive

Take the car for a test drive to ensure the new caliper is working properly. Take it slow at first and gradually build up speed. Test the brakes at various speeds to make sure they are responsive and effective.

Tips and Precautions

Always wear safety glasses and gloves when working on your car.
Make sure the car is on a level surface and the emergency brake is engaged before jacking it up.
Never reuse old brake fluid.
Make sure the brake pads are properly installed and secure before driving.

Conclusion

Converting the 2003 Audi S8 caliper onto a C5 A6 is a simple modification that can improve braking performance and reduce brake fade. With the right tools and materials, you can complete the installation in a few hours. Always take the necessary precautions and test the brakes before driving on the road.
