Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Secure the vehicle with jack stands.

3. Remove Wheel Assembly

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the brake components visually for any obvious issues.

4. Inspect and Replace Brake Pads

Inspect: Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
Replace: If pads are worn below 3mm, replace them.
- Remove the old pads and install new pads, ensuring they are properly aligned.
- Use brake grease on the backing of the pads to reduce noise.

5. Inspect and Replace Rotors (if necessary)

Inspect: Check the rotors for grooves, cracks, or excessive wear.
Replace: If the rotors are damaged or below the minimum thickness, remove the caliper bracket and rotor. Install new rotors and torque the caliper bracket bolts to the manufacturer’s specifications.

6. Reassemble

Slide the caliper back into position and replace the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Check

Remove the jack stands and lower the vehicle.
Torque the lug nuts to the specified value (usually around 76 ft-lbs for Camry).
Pump the brake pedal several times to seat the pads properly.
