Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the RAV4, depending on which caliper you are inspecting.
Secure the vehicle with jack stands to prevent it from falling.

3. Remove the Wheel

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

4. Inspect the Caliper

Check the caliper for any signs of fluid leakage or physical damage.
Examine the mounting bolts for tightness; if loose, torque them to the manufacturer’s specifications (usually around 20-30 ft-lbs, but refer to the service manual).

5. Check Brake Pads

Remove the caliper by loosening the caliper bolts (typically requires a socket wrench).
Slide the caliper off the rotor and inspect the brake pads for wear. Replace if thickness is less than 3mm.
Check the caliper piston for proper retraction and condition.

6. Reassemble

If no issues are found, reinstall the caliper and ensure bolts are torqued properly.
Reinstall the wheel and lug nuts, and lower the vehicle back to the ground.

7. Test the Brakes

Pump the brake pedal a few times to ensure proper caliper operation and brake fluid pressure is restored.
