Solution

1. Preparation

Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather necessary tools and parts.
Wear safety goggles and gloves.

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
Remove Brake Caliper:
- Use a socket set to unbolt the caliper from its bracket.
- Carefully slide the caliper off the rotor. Do not let it hang by the brake line; support it with a bungee cord.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.
- Apply brake grease to the back of the pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: If rotors are scored or below the minimum thickness specification, they should be replaced.
Remove Brake Rotor:
- If the rotor is held with retaining screws, remove them.
- Slide the rotor off the hub.
Install New Rotor: Position the new rotor onto the hub and secure it with screws if applicable.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer's torque specifications (typically around 25-30 Nm, but verify with service manual).
Reinstall the wheel and lug nuts, tightening in a crisscross pattern to the specified torque (usually around 100 Nm).

6. Final Checks and Brake Testing

Lower the vehicle from the jack stands.
Pump the brake pedal a few times to ensure the pads seat against the rotors.
Check brake fluid level and top off if necessary.
