Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Use a socket set to remove the brake caliper bolts.
3. Carefully slide the caliper off the rotor and secure it with a bungee cord to avoid straining the brake line.
4. Remove the old brake pads from the caliper bracket.
5. Inspect the new brake pads for proper fit and apply brake grease on the backing plates to reduce noise.
6. Install the new brake pads into the caliper bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or damage.
2. If replacement is necessary, remove the rotor by unscrewing the retaining screws (if applicable).
3. Install the new rotor, ensuring it's seated properly on the hub.
4. Torque the retaining screws to the manufacturer's specifications.

4. Reinstall Brake Caliper

Sub-steps:
1. Slide the caliper back over the new brake pads and rotor.
2. Secure the caliper with the original bolts and torque them to the manufacturer's specifications.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque lug nuts to the manufacturer’s specifications.
2. Reconnect the battery.
3. Pump the brake pedal several times to ensure proper caliper functionality.
4. Test drive the vehicle at low speed to listen for any remaining noise.
