Solution

1. Preparation

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

2. Lift Vehicle

Use a jack to lift the front and/or rear of the Highlander, depending on which brakes are being serviced.
Secure with jack stands.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake assembly.

4. Remove Brake Caliper

Use a ratchet and socket to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor; support it with a bungee cord or rope to avoid straining the brake line.

5. Replace Brake Pads

Slide the old brake pads out of the caliper bracket.
Install new brake pads in the same position as the old ones, ensuring they are properly seated.

6. Inspect and Replace Rotors (if necessary)

If rotors are worn or damaged, remove the rotor by unscrewing the retaining screws and sliding it off.
Install new rotors, ensuring they are clean and correctly fitted.

7. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Secure the caliper using the mounting bolts and torque to manufacturer's specifications (typically around 20-30 ft-lbs).

8. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specification (usually 76-80 ft-lbs).

9. Test Brake Function

Pump the brake pedal a few times to seat the pads.
Check for proper brake function before driving.
