Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Unbolt the caliper using a socket wrench and secure it with a bungee cord to avoid strain on the brake line.
4. Remove the brake pads and inspect them for wear.
5. Remove the rotor by unscrewing the retaining screws if applicable.
6. Replace the rotors with new ones if they are below the minimum thickness or warped.

3. Replace Brake Pads

Sub-steps:
1. Install new brake pads into the caliper bracket.
2. Compress the caliper piston using a brake caliper tool.
3. Reattach the caliper over the new pads and torque bolts to manufacturer's specifications (usually around 25-35 ft-lbs).

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Request a four-wheel alignment, ensuring the specifications match those for the Toyota Corolla E140.

5. Final Assembly

Sub-steps:
1. Reattach the front wheels and torque lug nuts to the manufacturer's specifications (usually around 76-83 ft-lbs).
2. Lower the vehicle from the jack stands and remove the jack.
