Solution

1. Preparation

Tools Required: Socket set, torque wrench, flathead screwdriver, brake pad spreader, jack and jack stands, wheel chocks.
Safety Warnings: Ensure the car is on a flat surface, engage the parking brake, and wear safety glasses. Disconnect the 12V battery before starting work on the brakes to avoid any electrical issues.

2. Lift the Vehicle

Place wheel chocks behind the rear wheels.
Use a jack to lift the front or rear of the vehicle, depending on which brake pads are being replaced.
Secure the vehicle with jack stands.

3. Remove the Wheel

Use a socket set to loosen and remove the lug nuts.
Carefully take off the wheel and set it aside.

4. Remove Old Brake Pads

Locate the brake caliper and remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor. Do not pull on the brake line.
Use a brake pad spreader to compress the caliper piston back into its bore.
Remove the old brake pads from the caliper bracket.

5. Install New Brake Pads

Apply brake grease to the back of the new brake pads to reduce noise and ensure smooth operation.
Place the new brake pads into the caliper bracket in the correct orientation.
Reposition the caliper over the new brake pads and ensure it is seated properly.
Reinstall and torque the caliper bolts to manufacturer specifications (typically 25-30 Nm).

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the manufacturer's specifications (typically 130-150 Nm).

7. Final Checks

Reconnect the 12V battery.
Pump the brake pedal a few times to ensure proper brake pressure is restored.
