Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure stability during the repair.

3. Remove Wheel

Loosen lug nuts using a lug wrench.
Remove the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket set.
Slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Clean the caliper and bracket with brake cleaner.
Insert new brake pads into the caliper bracket, ensuring they are properly seated.

5. Reassemble Brake Components

Push the caliper piston back into the caliper using a brake caliper tool.
Position the caliper over the new brake pads and secure it with the caliper bolts. Torque to manufacturer specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to the specified torque (usually 75-85 ft-lbs).

6. Final Checks

Reconnect the battery and lower the vehicle.
Pump the brake pedal several times to ensure the pads seat correctly.
