Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather necessary tools and safety equipment.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads you are inspecting.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Using a socket set, loosen and remove the lug nuts.
Carefully take off the wheel and set it aside.

4. Inspect the Brake Pads

Visually check the brake pads through the caliper for thickness.
- Minimum thickness is generally around 3mm; replace if below this.
If necessary, remove the caliper:
- Unscrew the caliper mounting bolts using a socket set.
- Carefully lift the caliper off the rotor and support it with a bungee cord or similar to avoid straining the brake line.
Inspect the brake pad surface for uneven wear or damage.

5. Reassemble

If brake pads are in good condition, reattach the caliper and wheel:
- Secure the caliper with bolts, tightening to manufacturer specifications (usually around 25-30 Nm).
- Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and fully tighten the lug nuts in a star pattern to ensure even pressure.
