Replacing the brake discs on an Audi is a significant maintenance task that not only enhances safety but also improves the overall driving experience. As a trusted Audi Brake Disc supplier, we understand the importance of a well - adjusted braking system after such a replacement. In this blog, we'll guide you through the steps to properly adjust the braking system after replacing Audi brake discs.
Pre - replacement Checks and Preparations
Before you start the replacement process, it's crucial to conduct a series of checks. First, inspect the brake calipers. Look for any signs of damage, such as leaks or worn - out pistons. A damaged caliper can prevent the brake pads from making proper contact with the new brake discs, leading to uneven braking and potential safety hazards.
Next, examine the brake lines. Check for any cracks, bulges, or leaks. Faulty brake lines can cause a loss of hydraulic pressure, which is essential for the proper functioning of the braking system. Replace any damaged brake lines before proceeding with the brake disc replacement.
Gather all the necessary tools for the replacement, including a socket set, a torque wrench, a C - clamp, and a brake bleeder kit. Having the right tools on hand will make the process smoother and more efficient.
Brake Disc Replacement
The first step in replacing the Audi brake discs is to safely lift the vehicle and secure it on jack stands. Make sure the vehicle is on a level surface to prevent any accidents during the replacement.
Remove the wheels to access the brake calipers and rotors. Use the socket set to remove the bolts holding the caliper in place. Carefully lift the caliper off the rotor and hang it using a wire or a hook to avoid putting stress on the brake line.
Take out the old brake pads from the caliper bracket. You may need to use a C - clamp to compress the caliper pistons back into their housing. This will create enough space to install the new brake discs.
Install the new brake discs onto the hub. Ensure that the discs are properly aligned and seated. Use the torque wrench to tighten the wheel hub bolts to the manufacturer's specifications. Over - tightening or under - tightening these bolts can lead to problems such as uneven braking or disc warping.
Reinstall the brake pads into the caliper bracket and then reattach the caliper to the brake disc. Tighten the caliper bolts to the correct torque.

Brake Pad Bedding - in
After replacing the brake discs, it's essential to bed - in the new brake pads. Bedding - in is a process that helps to transfer a thin layer of friction material from the brake pads onto the surface of the brake discs. This creates an optimal contact surface between the pads and the discs, improving braking performance and reducing the risk of glazing.
To bed - in the brake pads, drive the vehicle at a moderate speed (around 30 - 40 mph) and apply the brakes gently several times. Avoid hard braking during the bedding - in process. After a few gentle stops, gradually increase the braking force, but still avoid full - force stops. Repeat this process for about 10 - 15 stops.
Brake Fluid Check and Bleeding
The brake fluid level should be checked after replacing the brake discs. If the fluid level is low, top it up with the recommended brake fluid for your Audi model.
Bleeding the brake system is also a crucial step. Air can enter the brake lines during the replacement process, which can cause a spongy brake pedal and reduced braking performance. Use a brake bleeder kit to remove the air from the brake lines. Start with the wheel farthest from the master cylinder and work your way towards the closest one.
Caliper Alignment
Proper caliper alignment is necessary to ensure even wear on the brake pads and discs. Check if the caliper is centered over the brake disc. If it's misaligned, it can cause uneven braking and premature wear of the brake components. Adjust the caliper mounting bolts if necessary to achieve proper alignment.
Testing the Braking System
Once you've completed all the adjustment steps, it's time to test the braking system. Take the vehicle for a short test drive in a safe area. Pay attention to the feel of the brake pedal. It should be firm and responsive. If the pedal feels spongy or if there's excessive play, there may still be air in the brake lines or a problem with the caliper.
Listen for any unusual noises such as squealing, grinding, or rattling when applying the brakes. These noises can indicate issues such as loose components, worn - out pads, or misaligned calipers.
Check for any pulling to one side when braking. This could be a sign of uneven braking, which may be caused by a misaligned caliper or a problem with the brake lines.
