Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel corresponding to the brake pads needing inspection.
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper and secure it with a strap to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Compare the thickness of old pads to new ones and replace if worn.
- Apply brake grease to the backing of the new pads to reduce noise during operation.
- Reassemble the caliper and wheel, tightening bolts to manufacturer specifications.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- If rotors are warped or scored, remove the caliper as above.
- Remove the caliper bracket and then remove the rotor from the hub.
- Clean the hub surface to ensure proper contact with the new rotor.
- Install the new rotor, ensuring it is properly aligned.
- Reinstall the caliper bracket and caliper, tightening to the specified torque.

4. Brake Fluid Change

Sub-steps:
- Locate the brake fluid reservoir and remove the cap.
- Use a brake bleeder kit to remove old fluid from the system.
- Refill with the manufacturer's recommended brake fluid type.
- Bleed the brake lines starting from the farthest wheel to the nearest, ensuring no air remains in the system.
