Solution

1. Preparation

• Gather tools and materials.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Disconnect the battery to avoid electrical issues during repairs.

2. Remove Wheel

• Tools Required: Jack, jack stands, lug wrench.
• Sub-steps:
  1. Loosen lug nuts slightly while the vehicle is on the ground.
  2. Use the jack to lift the vehicle and secure it with jack stands.
  3. Remove lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

• Tools Required: Socket set, brake pad tool, torque wrench.
• Sub-steps:
  1. Remove the caliper bolts using the socket set.
  2. Carefully lift the caliper off the rotor.
  3. Inspect the brake pads for wear; replace if the thickness is below 3mm.
  4. If replacing, compress the caliper piston using a brake pad tool.
  5. Install new brake pads, ensuring they are oriented correctly.
