Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Measure the thickness of the brake pads. If less than 3mm, replace them.
Inspect Brake Rotors:
- Check for scoring or grooves; if warped (more than 0.002 inches of runout), resurface or replace.
Replace Pads:
- Remove the caliper bolts and lift the caliper off the rotor.
- Remove old pads. Install new pads in the caliper bracket.
Replace Rotors (if necessary):
- Remove the rotor from the hub by removing the retaining screws (if applicable).
- Install the new rotor, ensuring it is seated properly.

4. Reassemble

Reinstall the caliper over the new pads and secure it with bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 76 ft-lbs for RAV4).

5. Final Checks

Pump the brake pedal a few times to ensure proper brake pad seating.
Check brake fluid levels and top off if necessary.
