Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is on a level surface and securely elevated on jack stands.
Disconnect the battery (if necessary) to avoid electrical issues during the repair.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the front wheels using a socket wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

Sub-steps:
1. Use a socket set to remove the caliper mounting bolts.
2. Carefully lift the caliper off the rotor and support it using a bungee cord or similar device to avoid stress on the brake line.
3. Remove the brake pads from the caliper bracket.

4. Inspect and Replace Brake Rotors

Sub-steps:
1. Inspect the rotors for warping using a dial indicator; replace if necessary.
2. If rotors are not warped, consider resurfacing them if within specifications.
3. If replacing, remove the rotor by unscrewing the retaining screws or using a hammer to carefully tap it off the hub.

5. Install New Brake Pads and Rotors

Sub-steps:
1. Clean the new rotors with brake cleaner to remove any protective coating.
2. Install the new rotor onto the hub, securing it with retaining screws if applicable.
3. Apply brake grease to the back of the new brake pads and install them into the caliper bracket.
4. Reattach the caliper over the new pads and secure it with the mounting bolts, tightening to the manufacturer's specifications (usually around 20-30 ft-lbs).

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications (typically 76 ft-lbs for Camry).
3. Reconnect the battery if it was disconnected.
