Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure no electrical shorts occur.

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the pads; replace if less than 3mm.
- Look for uneven wear or damage.
Replace Brake Pads:
- Use a caliper tool to retract the caliper piston.
- Remove the caliper bolts using a socket set and lift the caliper off.
- Slide out the old brake pads and insert the new ones.
- Reattach the caliper and torque bolts to manufacturer specifications (typically around 25-30 Nm).

4. Inspect and Replace Brake Rotors

Inspect Brake Rotors:
- Measure rotor thickness; replace if below minimum specifications.
- Check for grooves or significant scoring.
Replace Brake Rotors:
- Remove the caliper bracket bolts and take off the bracket.
- Remove the rotor (may require tapping with a hammer if stuck).
- Install new rotor and reattach caliper bracket with appropriate torque (typically around 80-100 Nm).

5. Reassemble

Reinstall the wheel and torque lug nuts in a star pattern to the manufacturer's specification (usually around 110 Nm).
Lower the vehicle from jack stands.

6. Reconnect Battery

Reconnect the battery and ensure all electrical components are functioning.
