Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Remove the wheel to access the brake assembly.

3. Remove Brake Caliper

Use a socket set to remove caliper mounting bolts.
Carefully slide the caliper off the rotor and suspend it using a wire or bungee cord (do not let it hang by the brake line).

4. Inspect Components

Check brake pads for uneven wear; replace as necessary.
Inspect the caliper for proper function; clean and lubricate sliding pins.
Measure rotor thickness; replace if below manufacturer specifications or if warped.

5. Install New Brake Pads

Apply brake grease to the back of new pads to reduce noise.
Position new pads into the caliper bracket.
Reinstall caliper, ensuring it slides freely on its pins.

6. Reassemble

Reattach the wheel and tighten lug nuts to manufacturer-recommended torque specifications (usually around 80-100 ft-lbs for the Golf MK7.5).
Reconnect the battery.

7. Final Checks

Bleed the brake system if necessary to remove air.
Test the brake pedal feel before driving.
