Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools and parts.
Safety warning: Ensure the vehicle is in gear or in "Park" mode.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
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

Remove the caliper by unscrewing the caliper bolts using a socket set.
Lift the caliper off the rotor and secure it with a bungee cord (do not let it hang by the brake line).
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged, remove them by unscrewing the rotor screws (if equipped).
Clean the hub surface with a wire brush to ensure proper seating of the new rotor.
Install new rotors and secure them with screws.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands.
Tighten the lug nuts in a crisscross pattern to the specified torque (usually around 80-100 ft-lbs).
Pump the brake pedal a few times to seat the pads against the rotors.
