Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen lug nuts slightly using a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Remove caliper bolts using a socket set and carefully slide the caliper off the rotor.
Support the caliper using a bungee cord or similar device to avoid hanging the brake line.
Measure the rotor thickness with a micrometer; if below manufacturer specifications, replace the rotor.
If the rotor is warped, replace it with a new one. Ensure the new rotor is properly matched for the Highlander.
Clean the hub surface with a wire brush to remove rust or debris before installing the new rotor.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of leaks or damage.
Install new brake pads, ensuring they are properly oriented and seated in the caliper bracket.

5. Reassemble Components

Reattach the caliper over the new pads and secure it with the caliper bolts. Torque the bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque.

6. Test Drive

After the repair, perform a test drive to ensure the vibration issue is resolved.
