Solution

1. Preparation

Tools Required: Socket set, jack stands, lug wrench, brake cleaner, safety goggles, gloves.
Ensure the vehicle is on a flat surface and engage the parking brake. Disconnect the battery for safety.

2. Wheel Removal

Loosen the lug nuts of the rear wheels using a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the rear wheels to access the brake components.

3. Brake Inspection

Inspect the brake pads:
- Remove the brake caliper by unbolting it from the bracket.
- Check the thickness of the brake pads. Replace them if they are below the manufacturer’s minimum specification (typically 3mm).
Inspect the brake rotors:
- Check the surface of the rotor for grooves, scoring, or warping. Replace if necessary.
- Clean the rotor using brake cleaner to remove dust and debris.
Inspect brake calipers:
- Check for signs of sticking or corrosion. If the caliper is damaged, replace it.

4. Reassembly

Reinstall the brake caliper over the new or inspected brake pads.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 Nm).
Reattach the rear wheels and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually 100-120 Nm).

5. Brake Fluid Check

Check the brake fluid reservoir. If low, replenish with the appropriate brake fluid (usually DOT 4 for VW).
Bleed the brake lines if air was introduced during the inspection.
