Solution

1. Preparation

Gather necessary tools and park the vehicle on a flat surface.
Ensure the vehicle is in gear or in "Park" mode and engage the parking brake.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench.

2. Wheel Removal

Using a lug wrench, loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and securely place it on jack stands.
Remove the lug nuts and take off the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Examine brake pads for wear indicators; if the pads are worn down to the indicators, replace them.
Remove the caliper bolts using a socket wrench and carefully detach the caliper from the rotor.
Take out the old brake pads from the caliper bracket.
Install new brake pads by sliding them into the caliper bracket.

4. Inspect Brake Rotor

Check the brake rotor for scoring, grooves, or excessive rust.
If the rotor is damaged or below minimum thickness specifications, it should be replaced.
If the rotor is in good condition, consider resurfacing if necessary.

5. Reassemble and Torque

Reattach the caliper over the new brake pads and secure it with caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer's specifications.

6. Final Check

Refill brake fluid if necessary and check for any leaks.
Test the brakes by pressing the pedal several times to ensure proper function before driving.
