Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety gear (gloves, goggles).

2. Wheel Removal

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

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a dial indicator or by visual inspection.
- If warped, replace rotors.
Check Brake Pads:
- Measure thickness; if below specifications, replace.
Caliper Inspection:
- Ensure calipers are not sticking; clean or replace as needed.

4. Reassemble Components

Install new or resurfaced rotors if applicable.
Install new brake pads according to manufacturer specifications.
Reinstall the caliper and ensure it moves freely.
Reattach the wheel and hand-tighten lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer's specifications (typically between 75-85 ft-lbs for RAV4).

6. Final Inspection and Testing

Check for any leaks from the brake system.
Test drive the vehicle to ensure that shaking during braking is resolved.
