Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Engage the parking brake and place wheel chocks behind the rear wheels.

2. Lift the Vehicle

Use a jack to lift the front of the RAV4 and secure it on jack stands.
Remove the front wheels using a socket set.

3. Inspect the Brake Pads

Locate the brake caliper and remove the caliper bolts with a socket wrench.
Carefully slide the caliper off the brake rotor; support it with a bungee cord to avoid strain on the brake line.
Inspect the brake pads for wear. If they are less than 3mm thick, they need replacement.

4. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new brake pads to prevent noise and ensure smooth operation.
Install the new brake pads in the caliper bracket.
Reinstall the caliper over the new brake pads and tighten bolts to the manufacturer's specifications (usually around 25-30 ft-lbs).

5. Reassemble and Lower the Vehicle

Reattach the wheels and tighten the lug nuts in a crisscross pattern to the manufacturer's torque specifications (typically 76 ft-lbs).
Lower the vehicle off the jack stands and remove the jack.
