Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the wheel corresponding to the affected brake.
Raise the vehicle using the jack and secure it on jack stands.
Remove the wheel to gain access to the brake assembly.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it without straining the brake line.
- Inspect the brake pads for thickness; replace them if they are worn down to the wear indicators.
Brake Rotors:
- Check the rotor surface for deep grooves or scoring.
- If damaged, resurface or replace the rotors as necessary.
- Ensure the rotor is clean and free of rust or debris.

4. Reassemble Brake Components

If brake pads or rotors were replaced, install the new pads and/or rotors.
Reattach the caliper and tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs for most Toyota models).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower the Vehicle

Remove the jack stands and lower the vehicle.
Tighten the lug nuts to the specified torque (typically 76 ft-lbs for a Toyota Corolla).

6. Final Inspection

Reconnect the battery.
Test the brake pedal for firmness before driving.
