Replacing your brake pads is a routine maintenance task that many car owners can tackle at home, saving money and gaining a better understanding of their vehicle. If you drive a 2022 VW Taos SE FWD and notice your rear brake pads are wearing thin or producing excessive dust, like the original author experienced, it might be time for a replacement. This guide walks you through the process, addressing a common question: do you need an Audi Scan Tool Parking Brake function for this job?
The original poster successfully replaced their rear brake pads in about 45 minutes, using ceramic pads for better performance and less dust. Let’s break down the steps involved, based on their experience and best practices for brake service.
First, gather your tools and parts. For this job, you’ll need:
- New ceramic brake pads (like the DFC 3000 mentioned, part # 1310-1761-00)
- 7mm hex bit (for caliper pins)
- 17mm hex socket (for lug nuts)
- Screwdrivers (flat head, various sizes)
- Alligator clip leads
- Jumper cables
- 12V power source (car battery works well)
- Pry bar
- Torque wrench

Step-by-Step Brake Pad Replacement
-
Preparation and Safety: Ensure the vehicle is parked on a level surface, securely chocked, and the parking brake is disengaged (if possible, though we’ll address the electronic parking brake shortly). Gather all your tools and parts within easy reach.
-
Accessing the Brakes: Loosen the lug nuts on the rear wheel you’re starting with. Safely lift the vehicle using a jack and secure it with jack stands. Remove the wheel.
-
Disconnecting the Electronic Parking Brake Motor: This is where the question of an audi scan tool parking brake tool comes in. Modern vehicles, like the Taos, often have electronic parking brakes that require retraction before you can replace the rear pads. However, as the original poster demonstrated, it is possible to retract the motor manually without a scan tool in this case.
- Locate the brake motor wire connector on the rear caliper.
- Carefully pry the top tab on the connector to release it.
- Use a larger screwdriver to gently pry the connector away from the motor. It should detach relatively easily.
- Inside the connector (motor side), identify the two prongs. The negative prong is on the flat side of the connector.
- Using alligator clips connected to a 12V power source (like your car battery), apply power to the prongs to retract the parking brake motor. Important: Apply power for short bursts (around 10 seconds). You’ll hear a change in the motor sound when it’s retracted. The original author used a plastic knife as insulation to prevent short circuits, a good safety precaution. Reverse polarity to extend the motor if needed, although retraction is the goal here.

Caliper Removal and Pad Replacement:
- Remove the outer pad clips with a screwdriver if present (Taos specific).
- Use a 7mm hex bit to remove the two caliper pin bolts.
- Carefully remove the caliper. Do not let it hang by the brake hose. Rest it on a bucket or suspend it with wire to avoid hose damage.
- Remove the old brake pads. Note their orientation for installing the new pads correctly.
- Clean the caliper bracket and inspect the rotor.
- Install the new ceramic brake pads.
-
Piston Retraction: To accommodate the new, thicker brake pads, you need to retract the caliper piston. The original author used the old pads and a steel plate with a pry bar. This method works if the piston moves easily. Alternatively, a C-clamp can be used for a more controlled piston retraction. Avoid damaging the piston boot.
-
Reassembly:
- Reinstall the caliper, ensuring the new pads are correctly positioned.
- Tighten the caliper pin bolts to 26 ft lbs using a torque wrench.
- Reconnect the electronic parking brake motor connector. Ensure it clicks into place.
- Reconnect any rubber plugs or wire clips.
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to 104 ft lbs.
-
Parking Brake Reset and Bedding In:
- Parking Brake Reset: After reassembly, it’s crucial to engage and retract the parking brake several times (around 3 times) to reset and adjust it properly. This ensures the electronic parking brake functions correctly with the new pads. If you were using an audi scan tool parking brake function, this step might be automated or guided by the tool. Since we did it manually, cycling the brake pedal and parking brake lever/button should suffice.
- Bedding In New Pads: Follow the brake pad manufacturer’s recommendations for bedding in the new ceramic pads. This usually involves a series of moderate to firm stops from medium speeds to transfer brake pad material to the rotor for optimal braking performance.
Do You Need an Audi Scan Tool Parking Brake Tool?
For this specific 2022 VW Taos rear brake pad replacement, the original poster successfully bypassed the need for an audi scan tool parking brake tool by manually retracting the electronic parking brake motor with a 12V power source.
However, it’s important to note that:
- Not all vehicles are the same. Some electronic parking brake systems may be more complex and require a scan tool for proper retraction and to avoid error codes.
- Scan tools offer convenience and safety. An audi scan tool parking brake function, or a similar OBD-II scan tool with EPB (Electronic Parking Brake) service functions, can automate the retraction and reset process, potentially reducing the risk of damage or errors.
- For professional mechanics or frequent DIYers, a scan tool is a worthwhile investment. Tools like VCDS (VAG-COM Diagnostic System) or other professional-grade scanners provide comprehensive diagnostics and service functions for Audi, VW, and other VAG group vehicles, including parking brake service.

Conclusion
Replacing rear brake pads on a 2022 VW Taos can be a DIY-friendly task. While an audi scan tool parking brake function isn’t strictly necessary for this model based on the described method, understanding when and why such tools are used is crucial. If you are unsure or working on a different vehicle, consulting your vehicle’s repair manual or using a scan tool to retract the electronic parking brake is always the safest and recommended approach. Remember to prioritize safety, use quality parts, and enjoy the satisfaction of maintaining your vehicle yourself!
