Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, brake rotor removal tool, torque wrench.
Lift the vehicle and remove the front wheels using the lug wrench.
Remove the brake caliper by unbolting it and hanging it securely (do not let it dangle on the brake line).
Remove the brake pads from the caliper bracket.
Inspect the rotors for warping by using a dial gauge or visually checking for uneven surfaces.
If warped, remove the rotor by unscrewing the retaining screws and pulling it off the hub.
Install new rotors, ensuring they are clean and properly oriented.
Reinstall the brake pads and caliper, ensuring all bolts are torqued to manufacturer specifications (typically 79 ft-lbs for caliper bolts).

3. Inspect and Replace Brake Pads

If brake pads are worn unevenly, replace them with new pads compatible with the Toyota Corolla E140.
Apply brake grease to the backing plate of the new pads to reduce noise.

4. Inspect Suspension Components

Check control arms, tie rods, and struts for play or damage.
Replace any worn components as necessary to ensure proper alignment and handling.
