Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and set the parking brake.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a socket set before lifting the vehicle.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove lug nuts completely and take off the wheel.

3. Inspect Brake Components

Sub-steps:
1. Inspect brake pads for thickness; replace if less than 3mm.
2. Check brake rotors for grooves or damage; replace if necessary.
3. Assess calipers for movement; ensure they are not seized.

4. Replace Brake Pads and/or Rotors (if necessary)

Sub-steps:
1. Remove caliper bolts with a socket set and slide caliper off the rotor.
2. Remove old brake pads.
3. If replacing rotors, remove the rotor by unscrewing the retaining screws (if applicable) and slide off.
4. Install new rotor (if applicable) and new brake pads, ensuring proper orientation.
5. Reattach caliper over new pads and torque bolts to specifications (typically 25-35 Nm depending on specifications).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 100-120 Nm).
2. Lower the vehicle and reconnect the battery.
3. Pump the brake pedal a few times to seat the pads against the rotor before driving.
