Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Wheel

Using a socket set, loosen the lug nuts slightly before raising the vehicle.
Lift the vehicle with a jack 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 by unscrewing the caliper bolts with a socket wrench.
Carefully slide the caliper off the brake rotor and support it (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Compare the thickness of the old pads with new ones to ensure replacement is necessary.
If replacing, install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or uneven wear.
If damaged, remove the rotor by unscrewing the retaining screws or bolts.
Clean the hub surface with brake cleaner to ensure proper contact.
Install the new rotor, ensuring it is seated properly.

5. Reassemble Brake Components

Slide the caliper back over the new pads and rotor.
Reattach the caliper by tightening the caliper bolts to the manufacturer’s torque specification (typically around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque (usually 75-80 ft-lbs).
Reconnect the battery.
Pump the brake pedal a few times to ensure proper brake pad seating.
