Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery if working on electronic brake components.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads; if less than 3mm, replace.
Replacement:
1. Remove the caliper bolts with a socket.
2. Slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors

Inspection: Check rotors for grooves or excessive wear.
Replacement:
1. If replacing, remove the rotor by unscrewing the retaining screws.
2. Clean the hub surface with brake cleaner.
3. Install new rotor and secure it with screws.

5. Reassemble Components

Reinstall the caliper over new brake pads.
Torque caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to 80-100 ft-lbs in a star pattern.

6. Final Checks

Reconnect the battery (if disconnected).
Pump the brake pedal to ensure pads are seated properly before driving.
