Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Wheel

Using a socket set, loosen the lug nuts slightly while the wheel is still on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel completely to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off the rotor and suspend it (do not let it hang on the brake line).
- Inspect the brake pads for thickness; replace if they are below 3mm.
Brake Rotors:
- Check the surface of the rotors for any scoring or warping.
- If damaged, replace the rotors.
Calipers:
- Inspect calipers for proper movement and look for signs of leakage.
- If the caliper is seized or leaking, replace it.

4. Replace Components

If brake pads are worn, replace them with new ones.
If rotors are damaged, remove them and install new rotors.
Reinstall the caliper and torque the caliper bolts to manufacturer specifications (typically around 20-25 ft-lbs).

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then fully tighten the lug nuts in a star pattern to the manufacturer's torque specifications (usually around 100-150 ft-lbs).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal to ensure proper brake engagement before driving.
