Solution

1. Preparation

Tools Required: Jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a flashlight.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel on the affected side using a lug wrench.

2. Inspect Brake Pads

Remove the brake caliper by loosening the caliper bolts with a socket set.
Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the brake pads from the caliper bracket.
Inspect the pads for wear; replace if thickness is less than 3mm or if there are any visible cracks or damage.

3. Inspect Brake Rotors

Check the rotor surface for grooves, scoring, or warping.
If warped or scored, use a rotor gauge to measure thickness; if out of specification, replace the rotors.
Clean the rotor surface with brake cleaner to remove any dust or debris.

4. Reassemble Braking Components

If brake pads and rotors are in good condition or after replacement, slide the new or cleaned brake pads back into the caliper bracket.
Reattach the caliper over the brake pads.
Tighten the caliper bolts to the manufacturer's specified torque (usually around 20-25 ft-lbs, but check the service manual for exact values).

5. Reinstall Wheel and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque (typically around 80-100 ft-lbs).
