Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, safety goggles, gloves.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheels using a lug wrench.

2. Inspect Brake Components

Sub-steps:
- Remove the brake caliper by loosening the caliper bolts with the appropriate socket.
- Carefully slide the caliper off the rotor and hang it using a wire or bungee cord to avoid stress on the brake line.
- Remove the brake pads from the caliper bracket. Inspect for even wear; replace if worn down excessively.
- Check the rotors for any grooves or warping. Measure thickness using a micrometer.

3. Clean and Replace Components

Sub-steps:
- Clean the brake components using brake cleaner to remove dust and debris.
- Replace brake pads if they show significant wear, ensuring they are compatible with the MK6.
- If the rotors are worn beyond specification, replace them with new ones, ensuring to follow manufacturer specifications for thickness.

4. Reassemble and Test

Sub-steps:
- Reattach the caliper over the new or cleaned rotor and brake pads.
- Torque the caliper bolts to the manufacturer's specified torque value (typically around 25-35 Nm for VW).
- Reinstall the wheels and torque the lug nuts to the specified value.
