Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord or hang it to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Compare the thickness of the old pads with the new ones to ensure proper replacement.
Install the new brake pads into the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check the brake rotor for any deep grooves or scoring. If damaged, remove the rotor by unscrewing the rotor retaining screws if present.
Clean the hub surface and apply brake cleaner to remove any debris.
Install the new rotor, ensuring it is seated correctly.

5. Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque settings (usually around 20-25 ft-lbs).
Reinstall the wheel, hand-tightening the lug nuts.

6. Final Check

Lower the vehicle from jack stands and remove the jack.
Tighten the lug nuts in a crisscross pattern to the manufacturer’s specified torque (typically around 76 ft-lbs).
Reconnect the negative battery terminal.
