how to check for brake pad wear on my Volkswagen Passat B8 (2015-2022)?

Solution

1. Preparation

• Gather necessary tools: lug wrench, jack, jack stands, caliper gauge, and flashlight.
• Park the vehicle on a level surface and engage the parking brake.
• Wear safety gloves and goggles for protection.

2. Remove Wheel

• Loosen the lug nuts slightly while the vehicle is on the ground.
• Use the jack to lift the vehicle and securely place it on jack stands.
• Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Pads

• Locate the brake caliper and use a caliper gauge to measure the pad thickness.
• If the thickness is less than 3mm, replacement is necessary.
• Check for uneven wear or damage on the pads.

4. Inspect Brake Rotors

• Visually examine the rotors for any deep grooves, scoring, or rust.
• Use a micrometer to measure rotor thickness; ensure it meets manufacturer specifications.

5. Reassemble

• If pads are acceptable, reinstall the wheel, tightening the lug nuts by hand.
• Lower the vehicle from the jack stands and use the torque wrench to tighten lug nuts to the manufacturer’s specified torque (typically around 90-100 ft-lbs).
• Replace any components as necessary.
