Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent accidental electrical discharge.

2. Raise the Vehicle

Use a jack to lift the front or rear end of the vehicle, depending on which brake pads you are replacing.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Place the wheel aside in a safe location.

4. Remove the Brake Caliper

Locate the caliper bolts and remove them with a socket wrench.
Carefully slide the caliper off the rotor. Do not let it hang by the brake line; use a bungee cord or similar to secure it.

5. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Use a brake caliper tool to compress the caliper piston back into the housing to make space for the new pads.
Install the new brake pads into the caliper bracket, ensuring they are seated correctly.

6. Reinstall the Brake Caliper

Slide the caliper back over the new brake pads.
Reinstall and tighten the caliper bolts to the manufacturer's specified torque (typically around 25-30 ft-lbs).

7. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts to the specified torque (typically around 100 ft-lbs).

8. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure the brake pads seat properly against the rotor.
