Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the electrical components.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads for uneven wear or damage.
Check the brake rotors for any visible scoring, warping, or rust.
If the pads are worn down to the indicator, they need replacing.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Insert new brake pads, ensuring they are oriented correctly.
Reinstall the caliper over the new pads and secure it with bolts to the specified torque (usually around 25-35 ft-lbs).

5. Replace Brake Rotors (if necessary)

If rotors are damaged, remove the caliper bracket and rotor.
Clean the hub surface before installing the new rotor.
Install the new rotor and reattach the caliper bracket.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer’s specified torque (typically 76-86 ft-lbs for RAV4).
Reconnect the battery and perform a test drive to ensure the grinding noise is resolved.
