Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, safety glasses, gloves.
Safety Warning: Ensure the vehicle is on a flat surface and securely supported with jack stands before starting work.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Jack up the vehicle and secure it with jack stands.
Remove lug nuts completely and take off the wheel.

3. Inspect Brake Components

Sub-steps:
- Use a brake cleaner to clean the brake caliper and rotor area.
- Remove the brake caliper by unbolting it from its mounting bracket (usually requires a socket set).
- Carefully slide the caliper off the brake rotor and support it with a bungee cord to avoid straining the brake line.
- Remove the brake pads from the caliper bracket.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- Inspect the brake pads; replace them if they are worn to the minimum thickness (usually 3mm or less).
- If rotors are scored or below the minimum thickness, replace them. Check manufacturer specifications for minimum thickness.
- Install new brake pads into the caliper bracket.
- If replacing rotors, unbolt the rotor and replace it with a new one, ensuring it is torqued to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and rotor.
Bolt the caliper back to the mounting bracket securely.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Test the brakes gently to ensure proper operation before driving.
