Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a caliper gauge.
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Remove Wheel

Loosen lug nuts slightly before raising the vehicle.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Clean Brakes

Visually inspect the brake pads for thickness; replace if less than 3mm.
Check the rotors for grooves or uneven wear; resurface or replace if necessary.
Clean the brake components using brake cleaner to remove dust and debris.

4. Lubricate Components

Apply brake grease to the back of the brake pads to reduce noise.
Lubricate the caliper slides and mounting points to ensure smooth operation.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 76 lb-ft for a Corolla).
Test the brakes by applying them gently in a safe area, checking for noise.
