Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Loosen wheel lug nuts slightly while the vehicle is on the ground.
Raise 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 Pads

Inspection:
- Remove the brake caliper by unscrewing the mounting bolts.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Replacement:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are correctly oriented and seated in the bracket.

4. Inspect and Replace Rotors (if necessary)

If the rotors are damaged or worn beyond specifications, they must be replaced:
- Remove the caliper bracket by unscrewing its bolts.
- Slide the rotor off the hub. If it is stuck, gently tap with a rubber mallet.
- Install the new rotor, ensuring it is seated properly.

5. Reassemble Braking System

Reinstall the caliper bracket and torque the bolts to manufacturer specifications (typically around 79 ft-lbs for Camry).
Reinstall the caliper over the new pads and secure it with bolts.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the manufacturer's torque specification (typically 76 ft-lbs).

6. Final Checks

Pump the brake pedal to seat the pads against the rotors.
Check brake fluid level and top up if necessary.
