Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Caliper

Locate the caliper mounting bolts and remove them using a socket set (usually 13mm).
Carefully slide the caliper off the rotor and hang it using a bungee cord or rope to avoid straining the brake line.

4. Inspect and Clean

Remove the brake pads from the caliper bracket.
Inspect the caliper piston for damage or corrosion; clean it with brake cleaner if necessary.
Check the caliper slider pins; clean and lubricate them with high-temperature brake grease.

5. Replace Components (if necessary)

If the caliper is damaged or the piston does not move freely, replace the caliper with a new or rebuilt unit.
Replace brake pads if they show signs of excessive wear.
Ensure that all components are compatible with the Volkswagen Tiguan.

6. Reassemble

Reinstall the caliper over the rotor and secure it with the mounting bolts; torque to manufacturer's specifications (usually around 25 Nm).
Reinstall the brake pads, ensuring proper orientation.
Reattach the wheel and hand-tighten the lug nuts.

7. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the pads against the rotor properly.
Check brake fluid levels and top off if necessary.
