Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent movement.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.

2. Remove the Wheel

Use the lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using the jack and support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Clean Brake Components

Use brake cleaner to clean the brake calipers, pads, and rotors.
Inspect the brake caliper slides for proper movement; lubricate if necessary.
Check for corrosion or debris that may prevent proper caliper function.

4. Replace Unevenly Worn Brake Pads

Remove the caliper mounting bolts using a socket wrench.
Carefully slide the caliper off the rotor. Do not let it hang by the brake line; support it with a bungee cord if necessary.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are the correct type for the vehicle.
Parts Required: New brake pads (ensure they are compatible with the MK5 Golf).

5. Reassemble the Brake System

Reposition the caliper over the new pads and rotor.
Reinstall the caliper mounting bolts and tighten to manufacturer specifications (typically around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Torque Lug Nuts

Lower the vehicle back to the ground.
Use the torque wrench to tighten the lug nuts to the specified torque (usually 120 Nm for VW Golf MK5).
