Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, bungee cord or rope.
Raise the vehicle using a jack and securely place it on jack stands.
Remove the wheel using a lug wrench.

2. Inspect and Replace Brake Pads

Remove the brake caliper bolts using a socket set.
Carefully lift the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
Inspect the brake pads for wear; if they are less than 1/8 inch thick, replace them.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they seat correctly in the bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping. If damaged, replace the rotors.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Clean the hub surface with brake cleaner to ensure a good fit for the new rotor.
Install new rotors, ensuring they are properly aligned.

4. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower the Vehicle and Test

Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque (usually 76 ft-lbs for the Camry).
Pump the brake pedal a few times to seat the pads against the rotors.
