Solution

1. Preparation

Gather tools and parts needed for repair.
Park the vehicle on a level surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they fit snugly in place.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged, remove them by unbolting from the hub.
Clean the hub surface to ensure proper installation of the new rotor.
Install the new rotor and torque bolts to manufacturer specifications (typically around 80-100 ft-lbs).

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Reinstall the wheel and torque lug nuts in a star pattern to the recommended torque (typically around 80-100 ft-lbs).

6. Lower Vehicle and Test

Carefully lower the vehicle off the jack stands and remove them.
Test the brake pedal for firmness and proper engagement before driving.
