Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake pad spreader, torque wrench.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the vehicle's 12V battery to prevent electrical issues during the procedure.

2. Raise the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which brake pads need replacement.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

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

4. Remove Brake Caliper

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the brake rotor and support it using a bungee cord or a wire to avoid stress on the brake line.

5. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the new pads with the old ones to ensure they are the correct size.
Install the new brake pads into the caliper bracket, ensuring they are seated properly.

6. Reassemble Components

Reinstall the brake caliper over the new pads and secure it with the caliper bolts; torque to manufacturer's specifications.
Reattach the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle off the jack stands using the jack.
Tighten the lug nuts to the manufacturer’s specified torque value.
