Upgrading Audi A4 B9 2017-2019 to 8N Brake Calipers

If you are looking to upgrade the brake calipers on your Audi A4 B9, then consider the 8N brake calipers. The 8N brake calipers offer better stopping power, improved heat dissipation, and a sportier look compared to the stock brake calipers. In this post, we will discuss the steps to upgrade your Audi A4 B9 to 8N brake calipers.

Step 1: Gather the Required Parts The first step in upgrading your Audi A4 B9 to 8N brake calipers is to gather the necessary parts. You will need the 8N brake calipers, brake pads, rotors, and brake lines. Make sure to get high-quality parts from a reputable manufacturer to ensure the safety and reliability of your braking system.

Step 2: Remove the Old Calipers and Brakes Once you have all the necessary parts, the next step is to remove the old brake calipers and brake pads. To do this, first, loosen the lug nuts on the wheel and lift the car using a jack. Then, remove the wheel and disconnect the brake line from the caliper. Next, remove the caliper bolts and slide the caliper off the rotor. Finally, remove the old brake pads from the caliper bracket.

Step 3: Install the New Calipers and Brakes Now that the old calipers and brakes are removed, it's time to install the new 8N brake calipers and brakes. First, attach the new brake pads to the caliper bracket. Then, slide the new rotor onto the wheel hub. Next, attach the new brake caliper to the bracket using the caliper bolts. Finally, connect the brake line to the new caliper.

Step 4: Bleed the Brakes Once the new calipers and brakes are installed, it's important to bleed the brakes to remove any air bubbles in the system. To do this, have a friend pump the brake pedal while you open the bleed valve on each caliper in turn. Keep doing this until you see clear fluid coming out of the valve.

Step 5: Test Drive and Bed-in the Brakes The final step is to test drive your Audi A4 B9 and bed-in the new brakes. To bed-in the brakes, drive at moderate speeds and apply the brakes gradually to bring them up to operating temperature. Then, perform a series of moderate-to-hard stops to transfer the brake pad material to the rotor surface. After this, avoid coming to a complete stop for several minutes to allow the brakes to cool down.

Conclusion: Upgrading your Audi A4 B9 to 8N brake calipers is a great way to improve your vehicle's braking performance and appearance. Follow these steps carefully, and you will be rewarded with a safer and more enjoyable driving experience.
