Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake rotor gauge, caliper tool, impact wrench (if available).
Safely park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts before lifting the vehicle.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Tools Required: Brake rotor gauge, impact wrench (if needed).
Check the brake rotors for warping using a gauge; replace if warping exceeds specifications (usually over 0.002 inches).
If replacement is necessary, remove the caliper by unbolting it from the bracket and hang it securely.
Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor and secure it with retaining screws if applicable.

4. Inspect and Replace Brake Pads

Inspect the brake pads for wear; replace them if they are below the manufacturer’s specified thickness (typically 3-4 mm).
Remove the caliper bracket bolts and take off the caliper to access the brake pads.
Swap out old pads with new ones, ensuring they are properly seated in the caliper bracket.

5. Reassemble and Torque Components

Reattach the brake caliper and ensure it is securely fastened.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque (usually around 76 lb-ft for Highlander).
