Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Lift the Vehicle

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

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for any warping or uneven surfaces on the rotors.
- If warped, proceed to replace.
Remove Rotors:
- Unscrew the caliper brackets using the appropriate socket.
- Lift the caliper off and secure it with a bungee cord to avoid stress on the brake line.
- Unscrew and remove the rotor from the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective oil.
- Install the new rotor onto the hub, ensuring it sits flat.
- Reattach the caliper bracket and torque the bolts to the manufacturer’s specification (usually around 25-35 Nm).

4. Replace Brake Pads

Remove Old Pads:
- Remove the old brake pads from the caliper bracket.
Install New Pads:
- Apply brake grease to the backing of the new pads to prevent squealing.
- Place the new pads into the caliper bracket.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (usually around 25-30 Nm).
Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (usually around 90-120 Nm).

6. Lower the Vehicle

Carefully lower the vehicle back to the ground.
Test the brakes by pressing the pedal a few times to seat the pads against the rotor.
