Replacing your Audi A5’s rear brake pads is a task you can tackle yourself with the help of a VCDS (VAG-COM Diagnostic System). This guide will walk you through the process, providing clear instructions and helpful tips to make the job straightforward.

Understanding the Importance of Timely Brake Pad Replacement

Before we dive into the how-to, it’s crucial to understand why timely brake pad replacement is vital for your safety and your Audi’s performance. Brake pads are your first line of defense against unexpected stops and hazards. Worn-out pads compromise your braking distance and can lead to more expensive repairs in the long run.

Gathering Your Tools and Parts

Having the right tools and parts at hand makes the replacement process smoother. Here’s what you’ll need:

• VCDS (VAG-COM Diagnostic System): Essential for retracting the Electronic Parking Brake (EPB).
• New rear brake pads: Choose high-quality pads compatible with your Audi A5 model.
• Torque wrench: Ensures bolts are tightened to the correct specifications.
• Lug wrench or breaker bar: To loosen the lug nuts.
• Jack and jack stands: For safely lifting and supporting your Audi A5.
• C-clamp or brake piston compressor: To compress the brake caliper piston.
• Anti-seize lubricant: Prevents future seizing of bolts.
• Brake cleaner: To clean the brake components.
• Gloves and safety glasses: For your protection.

Audi A5 Rear Brake Pads Replacement with VCDS: Step-by-Step Guide

Follow these steps carefully for a successful brake pad replacement:

1. Engage ‘Service Mode’ with VCDS: Connect your VCDS to your Audi A5’s OBD-II port. Go to [Select Control Module] > [53 – Parking Brake]. Select [Basic Settings] > [Group 007]. This will retract the Electronic Parking Brake (EPB) and allow you to access the rear brakes.

2. Prepare your Audi A5: Park your car on a level surface, engage the parking brake, and chock the front wheels.

3. Loosen lug nuts: Use the lug wrench or breaker bar to loosen the lug nuts on the rear wheel you’ll be working on first.

4. Lift and secure your Audi A5: Using the jack, lift the car at the designated jacking point near the rear wheel you’re working on. Place jack stands under the car for safety.

5. Remove the wheel: With the car securely lifted, fully remove the lug nuts and take off the wheel.

6. Access the brake caliper: Locate the brake caliper. You might need to remove a caliper retaining bolt or pin to swing the caliper out of the way.

7. Remove old brake pads: Carefully remove the old brake pads from the caliper bracket. Note their position for installing the new pads correctly.

8. Compress the caliper piston: Using a C-clamp or brake piston compressor, slowly compress the caliper piston back into its housing. This is essential to accommodate the new, thicker brake pads.

9. Install new brake pads: Insert the new brake pads into the caliper bracket, ensuring they are seated correctly.

10. Reassemble the caliper: Reinstall the caliper, securing it with the retaining bolt or pin.

11. Reinstall the wheel: Place the wheel back onto the hub and hand-tighten the lug nuts.

12. Lower the vehicle: Use the jack to lower the car slightly, then use the torque wrench to tighten the lug nuts to the manufacturer’s specification.

13. Repeat for the other side: Repeat steps 3-12 for the other rear wheel.

14. Exit ‘Service Mode’ with VCDS: With both sides complete, reconnect your VCDS and go back to the [53 – Parking Brake] module. Select [Basic Settings] > [Group 001]. This will properly set the Electronic Parking Brake (EPB) after the pad replacement.

15. Test your brakes: Before driving, pump the brake pedal several times to restore pressure. Conduct a test drive in a safe, controlled environment to ensure your new brakes are functioning correctly.

Common Questions About Audi A5 Rear Brake Pad Replacement

3. Why is VCDS necessary for Audi A5 rear brake pad replacement?

The Electronic Parking Brake (EPB) on the Audi A5 requires the use of a VCDS to retract and reset the system during the brake pad replacement process.
