Solution

1. Preparation

• Gather tools and parts needed.
• Ensure vehicle is parked on a level surface and secured with wheel chocks.
• Disconnect the battery for safety if working on electronic components.

2. Remove Wheel

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

3. Inspect and Replace Brake Components

• Tools Required: Socket set, torque wrench.
• Sub-steps:

  2. Detach the caliper from the rotor and support it using a bungee cord (do not let it hang by the brake line).
  3. Remove the rotor by unscrewing any retaining screws or bolts.
  4. Inspect the rotor for warping with a runout gauge; replace if necessary.
  5. Check brake pads for wear; replace if worn unevenly or below manufacturer specifications.
  6. Install new or resurfaced rotor and new brake pads.
  7. Reattach the caliper and torque bolts to manufacturer specifications.
