Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a caliper tool.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Use the lug wrench to loosen the lug nuts on the front and/or rear wheels.
Raise the vehicle using the jack and secure it with jack stands.
Remove the wheels.

3. Inspect Brakes

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully lift the caliper off the rotor, supporting it with a bungee cord or similar.
- Inspect the brake pads for wear; replace if thickness is less than 3mm.
Brake Rotors:
- Measure rotor thickness; replace if below manufacturer specifications.
- Look for scoring or grooves; if present, consider resurfacing or replacing.

4. Replace Components (if necessary)

Brake Pads:
- Remove old pads and install new ones, ensuring they sit properly in the caliper bracket.
Brake Rotors:
- If replacing, remove the old rotor and install the new rotor, securing it with the appropriate torque as per manufacturer specs.

5. Reassemble

Reattach the caliper over the new pads and rotor, securing it with the caliper bolts. Tighten to the specified torque.
Reinstall the wheels and tighten the lug nuts in a star pattern.

6. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle back to the ground.
Re-torque the lug nuts to the manufacturer’s specifications.
