Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Sub-steps:
1. Loosen lug nuts slightly while the wheel is on the ground.
2. Raise the vehicle using a jack and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Tools Required: Torque wrench, brake cleaner, C-clamp or brake tool
Sub-steps:
1. Inspect brake rotors for warping using a dial indicator.
  - If warped beyond specification (typically 0.002 inches), replace the rotors.
2. Check brake pads for thickness; replace if below 3mm.
3. Clean the rotor surface with brake cleaner.
4. If rotors are fine and pads worn, replace pads and ensure proper alignment.
5. Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 76 ft-lbs for RAV4).

4. Check Suspension and Wheel Bearings

Tools Required: Socket set, pry bar
Sub-steps:
1. Inspect suspension components (control arms, ball joints) for play.
2. Check wheel bearings by rocking the wheel; replace if any looseness is detected.
3. Reassemble any disassembled components.

5. Final Assembly and Testing

Reinstall the wheel and lower the vehicle.
Tools Required: Torque wrench
Sub-steps:
1. Torque the lug nuts again to manufacturer specifications.
2. Test drive the vehicle to ensure the shaking during braking is resolved.
