Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use wheel chocks for safety.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front or rear of the RAV4 depending on which brakes are being serviced.
Secure with jack stands.

3. Remove Wheel

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

4. Inspect and Remove Brake Pads

Locate the brake caliper and remove the caliper mounting bolts using a socket set.
Carefully lift the caliper off the rotor and support it with a bungee cord or wire to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.

5. Inspect and Replace Rotors (if necessary)

Check the rotors for wear; if they are below the minimum thickness or have significant scoring, replace them.
Remove the rotor by unscrewing the retaining screws and pulling it off the hub.
Install new rotors in reverse order of removal.

6. Install New Brake Pads

Apply brake grease to the back of the new brake pads to reduce noise.
Slide the new brake pads into the caliper bracket.

7. Reassemble Brake Components

Reposition the brake caliper over the new pads.
Tighten the caliper mounting bolts to the manufacturer's specified torque (typically around 20-25 ft-lbs).
Reinstall the wheel and lug nuts, tightening to the correct torque (generally 75-90 ft-lbs).

8. Lower Vehicle

Carefully lower the vehicle back to the ground.

9. Test Brakes

Before driving, pump the brake pedal a few times to ensure proper pad seating and to restore brake pressure.
