Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel using a lug wrench.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the brake rotor and support it without disconnecting the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper for damage and ensure the caliper slides freely.
- Install new brake pads in the caliper bracket, ensuring they fit securely.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotor condition; if excessively worn or scored, replace them.
- Remove the rotor by unscrewing the retaining screws (if applicable).
- Clean the hub surface with brake cleaner to ensure proper contact with the new rotor.
- Install the new rotor, securing it with the retaining screws.

4. Reassemble Braking System

Sub-steps:
- Reposition the caliper over the new brake pads and rotor.
- Tighten the caliper bolts to the manufacturer’s specified torque (typically around 25-30 ft-lbs).
- Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Test

Sub-steps:
- Lower the vehicle back to the ground.
- Tighten the lug nuts to the manufacturer’s specified torque (typically around 80-100 ft-lbs).
- Pump the brake pedal several times to seat the brake pads before driving.
