Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly (do not fully remove).
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Check the brake pads for wear indicators. If they are worn down to 3mm or less, they should be replaced.
- If replacement is necessary, use a socket set to remove the caliper bolts.
- Carefully lift the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotors for warping or scoring. If they are damaged, they should be replaced.
- Remove the rotor by taking off the retaining screws (if applicable) and sliding it off the hub.
- Install new rotors, ensuring they are clean and free of any grease.

5. Reassemble Components

Sub-steps:
- Reattach the caliper over the new brake pads.
- Tighten the caliper bolts to the manufacturer’s specified torque (usually around 20-30 Nm).
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and tighten the lug nuts to specified torque (typically around 100-120 Nm).

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure the pads seat properly against the rotors.
Check brake fluid level and add as necessary.
