2

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, and safety goggles.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands before starting any work.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are less than 3mm, they should be replaced.
Remove Old Pads:
1. Remove the caliper bolts with a socket.
2. Carefully slide the caliper off the rotor. Support the caliper with a bungee cord to prevent stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
Install New Pads:
1. Clean the caliper bracket and apply brake grease to the contact points of the new pads.
2. Place the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors: Check for warping or excessive wear. If they are below the minimum thickness specification or have deep grooves, they need replacement.
Remove Rotors:
1. If equipped, remove the retaining screws with a screwdriver.
2. Slide the rotor off the wheel hub.
Install New Rotors:
1. Clean the new rotor with brake cleaner to remove protective oil.
2. Slide the new rotor onto the hub and secure with retaining screws.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications (typically around 20-30 ft-lbs).
Reinstall the wheel, hand-tighten the lug nuts, then lower the vehicle.

6. Final Checks

Torque the lug nuts to the manufacturer's specifications (usually around 76 ft-lbs for the Highlander).
Pump the brake pedal several times to ensure proper brake pad seating.
Check brake fluid level and top off if necessary.
