why does my Toyota Highlander Third Generation (2014-2019) have a squeaky noise when braking?

Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and the engine is off.
• Gather tools and safety equipment.
• Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.

2. Remove Wheel

• Loosen the lug nuts on the affected wheel slightly while the vehicle is still on the ground.
• Raise the vehicle using a jack and secure it with jack stands.
• Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

• Check the brake pads for wear; they should be at least 1/8 inch thick.
  • If worn, replace the brake pads.
• Inspect the brake rotors for any grooves or warping.
  • If damaged, either resurface or replace the rotors.

4. Clean Brake Components

• Use brake cleaner to clean the brake pads, rotors, and calipers.
• Ensure there is no dust or debris on the brake surfaces, which can cause squeaking.

5. Reassemble Brake Components

• If brake pads are replaced, install the new pads in the correct orientation.
• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle and torque the lug nuts to the manufacturer specifications (typically 76-80 ft-lbs for Toyota Highlander).
