Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen lug nuts slightly while the wheel is still on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads and Rotors

Tools Required: Socket set, torque wrench, brake cleaner
Sub-steps:
1. Inspect the brake pads for thickness (replace if less than 3mm).
2. Check the rotors for grooves or scoring; replace if necessary.
3. If replacing rotors, remove caliper mounting bolts and detach the caliper.
4. Remove the old rotor and clean the hub surface with brake cleaner.
5. Install the new rotor and reattach the caliper.
6. Replace brake pads and ensure they are properly seated.

4. Check Brake Caliper Function

Tools Required: Brake cleaner, compressed air
Sub-steps:
1. Inspect caliper slides for smooth movement; clean and lubricate if necessary.
2. Verify that calipers are not sticking; test by pressing the brake pedal and observing caliper movement.

5. Reassemble and Torque Components

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer's specification (typically 76 ft-lbs for Corolla).

6. Test Drive

Ensure all tools are removed from the area and perform a test drive to check for vibrations.
