Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheels

Use a jack to lift the front of the vehicle and support it with jack stands.
Remove the lug nuts with a socket wrench and take off the front wheels.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts with a socket.
- Lift the caliper off the rotor and inspect the brake pads for uneven wear.
- Replace if worn below specifications (usually less than 3 mm).
Brake Rotors:
- Check the rotor surface for warping or grooves using a dial indicator or by visual inspection.
- If warped, replace the rotors. If just worn, consider resurfacing if within tolerance.

4. Reassemble Brakes

Install new brake pads and reattach the caliper to its mounting bracket.
Tighten the caliper bolts to the manufacturer's torque specification (usually around 25-30 ft-lbs).
Reinstall the wheels and hand-tighten the lug nuts.

5. Lower Vehicle and Test

Carefully lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer’s specification (typically 76 ft-lbs for most RAV4 models).
Test drive the vehicle to ensure that the shaking has been resolved.
