Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is off.
Engage the parking brake.
Gather necessary tools and parts.

2. Remove Wheel

Loosen the lug nuts on the wheel using a lug wrench.
Raise the vehicle using a jack and secure it with 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; support it with a bungee cord to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing plates; if they are damaged, replace them.
Insert new brake pads into the caliper bracket.
Apply brake grease on the back of the new pads to prevent squealing.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, remove them by unbolting the caliper bracket from the spindle.
Slide the rotor off the hub.
Clean the new rotor with brake cleaner to remove any protective oils.
Install the new rotor onto the hub and secure it with the appropriate bolts.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Tighten caliper bolts to the manufacturer's specified torque setting (usually around 20-25 ft-lbs, check specifications).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Check

Remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts in a crisscross pattern to the manufacturer’s torque specification (usually around 100-150 ft-lbs).
