Solution

1. Preparation

Gather tools and parts needed for maintenance.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel using a socket set.
- Inspect brake pad thickness; replace if worn below manufacturer specifications (typically 3mm).
- Remove the caliper by unscrewing the caliper bolts with a socket wrench.
- Slide the old brake pads out of the caliper bracket.
- Install new brake pads, ensuring they fit securely in the caliper bracket.
- Reattach the caliper and torque the bolts to the manufacturer's specifications (usually around 25-30 lb-ft for Corolla).

3. Inspect and Replace Brake Rotors

Sub-steps:
- If rotors are warped or below thickness specs, remove them from the hub.
- Clean the hub surface to ensure proper seating of the new rotor.
- Install new brake rotors, ensuring they are properly aligned.
- Torque rotor mounting hardware to the correct specifications (generally 40-50 lb-ft).

4. Brake Fluid Maintenance

Sub-steps:
- Check brake fluid level in the master cylinder reservoir.
- If the fluid is contaminated (dark in color), perform a brake fluid flush.
- Use a brake bleeder kit to remove old fluid and replace it with DOT 3 or DOT 4 fluid as specified in the owner’s manual.

5. Final Assembly and Testing

Sub-steps:
- Reinstall the wheel and torque lug nuts to the manufacturer's specifications (typically 76 lb-ft).
- Pump the brake pedal to ensure proper seating of brake pads and restore brake pressure.
- Perform a test drive to ensure brakes are functioning correctly and listen for any unusual noises.
