Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Disconnect the battery before working on the electrical components.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels using a socket set.

3. Inspect and Replace Brake Pads

Remove Calipers:
- Use a socket to remove the caliper mounting bolts.
- Carefully lift the caliper off the rotor without stretching the brake line.
Inspect Brake Pads:
- Check each brake pad for wear. Replace any pads that are worn unevenly or below the minimum thickness.
Install New Brake Pads:
- Apply brake grease to the back of the new brake pads to prevent noise.
- Install new pads in the caliper bracket. Ensure they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If rotors are warped or scored, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install New Brake Rotor:
- Clean the hub surface and install the new rotor. Secure with screws if applicable.

5. Reassemble and Lower Vehicle

Reattach the caliper over the new brake pads and secure it with the mounting bolts.
Reinstall the wheels and lower the vehicle back to the ground.

6. Brake System Bleeding

Bleed the brake system to remove any air, especially if the calipers were removed or brake fluid was low.
Use a brake bleeder kit to ensure all air is expelled from the lines.
