why is my Toyota Highlander XU70 (2020-Present) making a squeaking noise when I brake

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the ignition is off.
• Use wheel chocks to prevent movement.

2. Remove Wheel

• Tools Required: Lug wrench, jack, jack stands.
• Loosen the lug nuts slightly while the vehicle is on the ground.
• Raise the vehicle using a jack and place it securely on jack stands.
• Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

• Remove the brake caliper by unbolting it (typically two bolts).
• Tools Required: Socket set, torque wrench.
• Carefully lift the caliper and support it without stressing the brake line.
• Inspect brake pads for thickness; replace if less than 3mm.
• Check rotors for grooving or warping; replace if necessary.

4. Clean and Lubricate

• Clean the brake pads and caliper bracket using brake cleaner.
• Apply anti-squeal lubricant on the back of the brake pads and caliper contact points.
• Tools Required: Brake cleaner, anti-squeal lubricant, clean cloth.

5. Reassemble Brake Components

• Reinstall the brake caliper and torque bolts to manufacturer specifications.
• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle from the jack stands and tighten lug nuts in a star pattern to the specified torque.
