Solution

1. Preparation

Gather all necessary tools and parts.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts with a socket set.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of the old pads with new pads. Replace if worn beyond the manufacturer's specifications.
5. Apply brake grease to the back of the new pads to reduce noise.
6. Install the new pads into the caliper bracket.

3. Inspect and Replace Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or warping using a straightedge.
2. If damaged, remove the rotor by unscrewing the retaining screws and pulling it off the hub.
3. Install the new rotor, ensuring it’s seated properly on the hub.
4. Torque the rotor retaining screws to the manufacturer's specified value.

4. Reassemble the Braking System

Sub-steps:
1. Reposition the brake caliper over the new pads and rotor.
2. Tighten the caliper bolts to the manufacturer’s torque specifications.
3. Replace the wheel and hand-tighten the lug nuts.

5. Final Checks

Sub-steps:
1. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.
2. Pump the brake pedal to seat the brake pads against the rotors.
3. Check brake fluid level and top off if necessary.
