Preparation
 

• Ensure the car is parked on a level surface and the parking brake is engaged. Turn the ignition off and remove the keys to prevent any accidental starts.
• Gather necessary tools and materials such as a lug wrench, jack and jack stands, a C-clamp, brake cleaner, and the appropriate brake pads for a 2019 Audi A4.
• Wear safety goggles and gloves to protect yourself during the process.

 
Removing the Wheel
 

• Loosen the lug nuts on the wheel using a lug wrench. Do not remove them completely at this stage.
• Use a jack to lift the car off the ground and place jack stands under the car for support.
• Remove the lug nuts completely and take off the wheel, exposing the brake assembly.

 
Removing the Old Brake Pads
 

• Locate the brake caliper, which is generally mounted over the brake rotor.
• Remove the bolts securing the caliper to the caliper bracket using an appropriate socket or wrench. Be careful not to stretch, twist, or kink the brake line.
• Carefully slide the caliper off the rotor and secure it in a way that doesn't put stress on the brake hose, such as suspending it with a bungee cord.
• Take out the old brake pads from the caliper bracket. Note their positioning to help with installing the new ones.
• If applicable, remove the clips or retaining pins holding the pads in place.

 
Preparing for New Brake Pads
 

• Inspect the brake rotor for any damage or excessive wear. If necessary, have it replaced or resurfaced.
• Use brake cleaner to remove any debris or dust from the brake components.
• Compress the caliper piston using a C-clamp. Place one end of the clamp on the piston and the other on the back of the caliper housing, then tighten it until the piston is fully seated.

 
Installing the New Brake Pads
 

• Position the new brake pads into the caliper bracket in the same manner as the old pads were installed.
• Re-attach any clips or retaining pins that were removed.
• Carefully slide the caliper back over the rotor and reinstall the bolts to secure it to the caliper bracket. Torque the bolts to the manufacturer’s specified value.

 
Reinstalling the Wheel
 

• Place the wheel back onto the hub, aligning it with the lug bolts.
• Hand-tighten the lug nuts to hold the wheel in place.
• Lower the vehicle off the jack stands using the jack, ensuring the car is back on a stable surface.
• Tighten the lug nuts in a crisscross pattern to the specified torque rating for your vehicle.

 
Final Checks
 

• Start the car and pump the brake pedal a few times to seat the new brake pads properly.
• Check the brake fluid level in the reservoir and add more if necessary.
• Take the car for a short test drive at low speed to ensure the brakes function correctly.
