Solution

1. Preparation

Gather necessary tools and parts before starting.
Park the vehicle on a flat surface and ensure the engine is off.
Disconnect the battery to prevent any electrical issues.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a multimeter.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Compare the new pads to the old ones to ensure proper fit.
Apply brake grease to the back of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove them by unscrewing the rotor retaining screws.
Clean the hub surface where the rotor mounts using brake cleaner.
Install the new rotor onto the hub and secure with retaining screws.

5. Reassemble and Torque

Reposition the caliper over the new brake pads.
Tighten the caliper bolts to the manufacturer's torque specifications (consult vehicle manual).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.

6. Brake Fluid Check

Check the brake fluid level and top off if necessary with the recommended brake fluid type (DOT 4).
Bleed the brakes if air is suspected in the brake lines.
