Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather all necessary tools and parts.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts of the wheel corresponding to the affected brake.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid putting stress on the brake line.
- Inspect the brake pads for wear; replace if they are below the minimum thickness (typically 3mm).
Brake Rotors:
- Check the rotors for warping by using a dial indicator; if warping is present (more than 0.002 inches), consider resurfacing or replacing them.
- If replacing, remove the rotor by unbolting it from the hub.
- Install new rotors, ensuring proper alignment and torque the bolts to manufacturer specifications.

4. Reassemble Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque (usually around 25-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Test

Carefully lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs for RAV4).
Test drive the vehicle to ensure proper braking and check for any vibrations.
