Solution

1. Preparation

Gather tools and materials listed below.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Measure Rotors

Inspect rotors for any visible damage, scoring, or rust.
Use a dial indicator to measure rotor runout; replace if warping exceeds manufacturer specifications (typically 0.002 inches).
Clean the surface of the rotors with brake cleaner.

4. Replace Brake Pads (if worn)

Remove the caliper bolts using a socket wrench.
Detach the caliper and support it without stretching the brake line.
Replace worn brake pads, ensuring they fit correctly into the caliper bracket.
Reattach the caliper and torque the bolts to manufacturer specifications.

5. Reinstall Wheel and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts in a crisscross pattern.
Lower the vehicle and torque the lug nuts to the specified value (typically 76-80 ft-lbs for RAV4).

6. Test Drive

Conduct a test drive to ensure the issue is resolved and monitor for any vibrations while braking.
