Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Safely park the vehicle on a level surface, engage the parking brake, and turn off the ignition.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
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 Replace Brake Pads

Remove the caliper bolts using the socket set.
Carefully slide the caliper off the brake pads and support it with a bungee cord to avoid stress on the brake line.
Inspect the brake pads for wear. If they are worn down to the metal or have less than 1/8 inch of material left, replace them.
Install new brake pads by sliding them into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, remove the rotor by unscrewing the retaining screws (if present).
Replace with new rotors, ensuring they are correctly seated.
Torque the rotor retaining screws to the manufacturer's specifications.

5. Reassemble Components

Reattach the caliper over the new brake pads.
Tighten the caliper bolts to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque in a star pattern.
