Solution

1. Preparation

Gather Tools:
- Socket set
- Brake pad gauge
- Brake cleaner
- Torque wrench
- Jack and jack stands
Safety Warning: Ensure the vehicle is on a flat surface and engage the parking brake.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Use the brake pad gauge to measure the thickness of the brake pads; if below 3mm, replace them.
4. Remove the caliper bolts using a socket set.
5. Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
6. Remove the old brake pads and install new ones, ensuring they are seated properly.
7. Reinstall the caliper over the new pads and torque bolts to manufacturer specifications (typically around 25-30 Nm).

3. Inspect and Replace Brake Rotors

Sub-steps:
1. If rotors show signs of warping or scoring, remove them after removing the caliper.
2. Clean the hub surface with brake cleaner to ensure proper rotor seating.
3. Install new rotors, ensuring they are aligned correctly.
4. Torque rotor retaining screws if applicable.

4. Brake Fluid Maintenance

Sub-steps:
1. Check the brake fluid reservoir and top up with the correct type of brake fluid (DOT 4 for Tiguan).
2. If fluid is contaminated, perform a brake fluid flush by using a brake bleeder kit.
3. Bleed each brake line starting from the farthest wheel to the closest, ensuring no air is trapped.

5. Final Assembly

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to manufacturer specifications (typically around 120 Nm).
3. Test the brake pedal for firmness before driving.
