Solution

1. Preparation

Gather tools and parts: brake pads, socket set, brake cleaner, torque wrench, and jack stands.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle.
Securely place jack stands under the rear frame to ensure stability.

3. Remove the Wheel

Use a socket wrench to loosen and remove the lug nuts.
Remove the rear wheel to access the brake assembly.

4. Remove the Brake Caliper

Locate the caliper bolts using a socket wrench; typically, they are on the inside of the caliper.
Remove the caliper bolts and carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or a suitable hanger to avoid stress on the brake line.

5. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Compare new brake pads to ensure they match the old ones.
Apply brake grease to the backing of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.

6. Reinstall the Brake Caliper

Compress the caliper piston using a brake caliper tool or C-clamp to make room for the new pads.
Position the caliper over the new pads and align with the mounting bracket.
Reinstall and torque the caliper bolts to the manufacturer's specifications (typically around 80-100 ft-lbs).

7. Reinstall the 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 specifications (often 76 ft-lbs for the Highlander).

8. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper pad seating and to restore brake pressure.
