Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, caliper gauge or ruler, flashlight.
Ensure the vehicle is on a flat surface and securely engage the parking brake.

2. Lift the Vehicle

Using the jack, lift the front or rear of the vehicle depending on which brake pads are being checked.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Use the lug wrench to loosen and remove the lug nuts.
Take off the wheel to expose the brake assembly.

4. Inspect Brake Pads

Use the caliper gauge or ruler to measure the thickness of the brake pads.
- Minimum thickness should be around 3mm; replace if thinner.
Look for uneven wear; if one pad is significantly thinner than the others, it may indicate a problem.

5. Check Brake Rotors

Inspect the brake rotor surface for scoring or grooves.
If the rotor has deep grooves, consider having it resurfaced or replaced.

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs for Corolla).

7. Safety Check

Before driving, check the brake pedal feel to ensure proper operation.
