Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts during the repair.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Components

Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.

Brake Rotors (if necessary)

Sub-steps:
- Inspect the rotor surface for grooves or excessive wear.
- If damaged, remove the rotor by unscrewing the retaining screws or using a hammer to gently tap it free.
- Install new rotors, ensuring they are properly aligned.

4. Reassemble Components

Reattach the caliper over the new pads and rotor.
Torque caliper bolts to the manufacturer's specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).

5. Final Checks

Reconnect the battery.
Press the brake pedal a few times to seat the brake pads against the rotors.
Inspect for any leaks around the brake components.
