Solution

1. Preparation

Gather all necessary tools and parts.
Safely lift and support the vehicle using jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Remove the caliper and hang it securely (do not let it dangle by the brake line).
3. Remove old brake pads from the caliper bracket.
4. Inspect the caliper bracket for wear and clean it with brake cleaner.
5. Install new brake pads in the caliper bracket, ensuring they are seated properly.

3. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
1. Remove the caliper bracket from the rotor by unscrewing the mounting bolts.
2. Slide the rotor off the hub and inspect for any major grooves or warping.
3. If necessary, install new rotors, ensuring they are clean and free of grease.
4. Torque the rotor retaining bolts to the manufacturer's specifications.

4. Reassemble Brake Components

Sub-steps:
1. Reinstall the caliper bracket over the new rotor and torque bolts to specifications.
2. Reinstall the caliper over the new brake pads and torque caliper bolts to specifications.
3. Reattach the wheel and torque lug nuts to the manufacturer's specifications.

5. Final Checks

Sub-steps:
1. Connect the battery if disconnected.
2. Pump the brake pedal several times to seat the pads against the rotors.
3. Check brake fluid level and add fluid if necessary.
