Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake pad spreader, jack stands, wheel chocks, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the 12V battery to prevent any electrical issues during the process.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads you are replacing.
Secure the vehicle with jack stands and place wheel chocks behind the opposite wheels.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the brake assembly.

4. Remove the Brake Caliper

Locate the caliper bolts and remove them using the socket set.
Carefully slide the caliper off the rotor and support it using a bungee cord or a caliper hanger to avoid strain on the brake line.

5. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Use a brake pad spreader to compress the caliper piston back into the caliper housing to make room for the new pads.
Install the new brake pads into the caliper bracket, ensuring they are properly aligned.

6. Reinstall the Brake Caliper

Carefully slide the caliper back over the new brake pads and rotor.
Reinstall the caliper bolts and tighten them to the manufacturer's specified torque (usually around 25-30 ft-lbs, but check specific torque specs).

7. Reattach the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle back to the ground and use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically around 100-110 ft-lbs).

8. Reconnect Battery and Test

Reconnect the 12V battery.
Pump the brake pedal several times to ensure proper brake pad seating and to restore brake pressure.
Test drive the vehicle at low speeds to ensure proper brake function.
