Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat, stable surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the braking components.

4. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the brake caliper by unscrewing the caliper bolts with a socket set.
2. Secure the caliper to the suspension using a bungee cord (do not let it hang on the brake line).
3. Remove the brake pads from the caliper bracket.
4. Unscrew the rotor retaining screws (if applicable) and remove the rotor from the hub.
5. Install new rotors, ensuring they are properly seated.
6. Reattach the caliper and replace the brake pads.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs for RAV4).

6. Test Brake Functionality

Start the vehicle and gently test the braking system in a safe area.
Monitor for any vibrations or abnormal noises.
