Solution

1. Preparation

Gather Tools and Parts:
- Tools: Socket set, Torque wrench, Brake caliper tool, Flathead screwdriver, Jack and jack stands, Lug wrench, Brake cleaner
- Parts: New brake pads (front and/or rear), Brake lubricant
Safety Warning: Disconnect the 12V battery before starting to avoid any electrical issues.

2. Lift the Vehicle

Use the jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use the lug wrench to remove the wheel nuts and take off the wheel.

4. Remove the Brake Caliper

Sub-step: Use the socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor and support it with a bungee cord or a suitable hanger to avoid stress on the brake line.

5. Replace the Brake Pads

Sub-step: Remove the old brake pads from the caliper bracket.
Sub-step: Use the brake caliper tool to compress the caliper piston back into the caliper housing to make room for the new pads.
Sub-step: Install the new brake pads into the caliper bracket, ensuring they are seated properly.

6. Reinstall the Brake Caliper

Position the caliper over the new brake pads and rotor.
Reinstall the caliper mounting bolts and torque them to the manufacturer’s specifications (typically around 25-30 ft-lbs, check the service manual for exact values).

7. Reinstall the Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually around 100-120 ft-lbs).

8. Final Checks

Sub-step: Reconnect the 12V battery.
Sub-step: Pump the brake pedal a few times to seat the brake pads against the rotors.
