Solution

1. Preparation

Gather Tools: Collect necessary tools including a jack, jack stands, wheel chocks, lug wrench, and brake cleaner.
Safety Measures: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety gloves.

2. Raise the Vehicle

Loosen Lug Nuts: Slightly loosen the lug nuts on the affected wheel before lifting.
Jack Up the Vehicle: Use a jack to raise the vehicle and secure it with jack stands.
Remove Wheel: Fully remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Check Brake Pads: Measure the thickness of the brake pads; replace if worn down (less than 3mm).
Examine Rotors: Check rotors for scoring or warping; replace if necessary.
Inspect Calipers: Ensure calipers are functioning properly and not sticking.

4. Replace Worn Components

Remove Old Pads: If needed, unclip and remove the old brake pads.
Install New Brake Pads: Position new pads in the caliper bracket and secure them.
Resurface or Replace Rotors: If rotors are damaged, either resurface or replace them per manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall Wheel: Place the wheel back on, hand-tighten the lug nuts.
Lower Vehicle: Remove jack stands and lower the vehicle to the ground.
Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to manufacturer specifications (usually 76-80 ft-lbs for Corolla).
