Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Brake Components

Remove Wheel:
- Loosen the lug nuts with the lug wrench.
- Lift the vehicle using a jack and secure with jack stands.
- Remove the wheel.
Inspect Brake Pads and Rotors:
- Examine the brake pads for wear; replace if less than 1/8 inch thick.
- Check the brake rotors for grooves or scoring; replace if necessary.
Replace Brake Pads (if required):
- Remove caliper bolts with a socket set.
- Slide the caliper off and support it (do not let it hang by the brake line).
- Remove old brake pads and install new pads. Ensure they are positioned correctly.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically 20-25 ft-lbs).
Reinstall Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (usually 76 ft-lbs for Camry).

3. Check Wheel Bearings

Inspect Wheel Bearings:
- Spin the wheel by hand; it should turn smoothly without noise.
- If grinding persists, the wheel bearings may need to be replaced.
Replace Wheel Bearings (if necessary):
- Remove the brake rotor and caliper.
- Extract the wheel hub assembly and replace bearings using a press.
- Reassemble all components following previous steps.
