Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor; do not let it hang from the brake line.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they fit snugly in place.
- Lubricate the caliper slide pins with brake grease before reassembly.

4. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
- If rotors are warped or worn unevenly, remove them by unbolting the rotor from the hub.
- Clean the hub surface to ensure a proper fit for the new rotor.
- Install new rotors, ensuring they are properly aligned and secured.

5. Reassemble Components

Sub-steps:
- Reinstall the caliper over the new brake pads and secure it with bolts to the specified torque (typically 25-35 ft-lbs).
- Reattach the wheel and lower the vehicle.

6. Bleed Brake System (if necessary)

Sub-steps:
- If brake fluid was lost during the process, bleed the brake system using the appropriate sequence (usually starting from the farthest wheel from the master cylinder).
- Use a brake bleeder tool or have an assistant pump the brake pedal while you open and close the bleeder valve.

Tools Required:

Jack and jack stands
Socket set
Brake caliper tool (if needed)
