Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake pad spreader, brake cleaner, and safety goggles.
Ensure the vehicle is on a flat surface and the parking brake is engaged. Disconnect the battery if necessary to prevent electrical issues.

2. Raise Vehicle and Remove Wheels

Loosen lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts and take off the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with the appropriate socket.
- Carefully slide the caliper off the brake pads and support it using a bungee cord to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
- Check the caliper for any signs of leaks or damage.
- Clean the caliper and bracket with brake cleaner.
- Install new brake pads, ensuring they are seated correctly in the bracket.
- Reinstall the caliper and torque the bolts to the manufacturer’s specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Measure the rotor thickness with a micrometer; replace if below specifications.
If replacing, remove the caliper bracket and then the rotor.
Install the new rotor and reassemble the caliper bracket.

5. Reassemble and Final Steps

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the battery if it was disconnected.
Test the brake system by pressing the brake pedal several times to ensure proper operation before driving.
