Introduction

This tutorial will guide you through the process of changing the rear brake pads on an AUDI A4 B7 (2004–2008). Regular maintenance of your brake system is crucial for safety and optimal vehicle performance. Follow these steps to ensure a successful brake pad replacement.

Step 1: Prepare Your Vehicle

  • Gather Tools and Parts: Ensure you have the following:
    • New brake pads
    • A lug wrench
    • A socket set
    • A brake caliper tool or C-clamp
    • Brake cleaner
    • Safety gloves and goggles
  • Park Safely: Park your AUDI A4 on a level surface and engage the parking brake.

Step 2: Unscrew the Wheel Bolts

  • Loosen the Wheel Bolts: Using the lug wrench, slightly loosen the wheel bolts before lifting the vehicle.
  • Lift the Vehicle: Use a jack to lift the rear of the vehicle and secure it with jack stands.
  • Remove the Wheel: Fully unscrew and remove the wheel to access the brake components.

Step 3: Remove the Brake Caliper

  • Locate the Brake Caliper: Identify the brake caliper attached to the brake disc.
  • Unbolt the Caliper: Use a socket set to remove the bolts securing the caliper to the bracket.
  • Support the Caliper: Do not let the caliper hang by the brake line. Support it using a bungee cord or similar method.

Step 4: Remove the Retaining Springs

  • Identify Retaining Springs: Locate the springs holding the brake pads in place.
  • Remove the Springs: Carefully remove the retaining springs using pliers. Be cautious as they may snap back.

Step 5: Replace the Brake Pads

  • Remove Old Brake Pads: Take out the old brake pads from the caliper bracket.
  • Install New Brake Pads: Position the new brake pads in the same place as the old ones, ensuring they fit snugly.

Step 6: Press In the Brake Caliper Piston

  • Use a Brake Caliper Tool: To make space for the new pads, press the brake caliper piston back into the caliper using a brake caliper tool or a C-clamp.
  • Ensure Even Pressure: Apply pressure evenly until the piston is fully retracted.

Step 7: Reassemble the Caliper

  • Reattach the Caliper: Position the caliper over the new brake pads and secure it with the previously removed bolts.
  • Tighten the Bolts: Use a torque wrench to ensure the caliper bolts are tightened to manufacturer specifications.

Step 8: Reinstall the Wheel

  • Position the Wheel: Place the wheel back onto the hub.
  • Screw in the Wheel Bolts: Hand-tighten the bolts before lowering the vehicle.
  • Lower the Vehicle: Carefully remove jack stands and lower the vehicle back to the ground.
  • Fully Tighten Wheel Bolts: Use the lug wrench to securely tighten the wheel bolts in a criss-cross pattern.

Conclusion

You have successfully changed the rear brake pads on your AUDI A4 B7. Remember to test the brakes gently after the replacement to ensure everything is functioning correctly. Regularly check your brake system for wear and tear to maintain vehicle safety. If you feel unsure at any step, consider consulting a professional mechanic for assistance.
