2
Check brake rotors for scoring, warping, or uneven surfaces.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the key is removed from the ignition.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts of the wheel where the brakes are squeaking.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect brake pads for wear. Replace if they are worn down to 3mm or less.
Check the brake rotors for scoring or grooves. If damaged, consider resurfacing or replacing them.
Examine calipers for proper operation and ensure they are not stuck.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are positioned correctly in the bracket.
Apply brake grease to the backing of the pads to prevent noise.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and secure it with bolts, tightening to the manufacturer’s torque specifications (typically 25-35 ft-lbs for most Toyota models).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a criss-cross pattern to the specified torque (usually around 76 ft-lbs for Highlander).
