Solution

1. Preparation

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

2. Remove Wheel

• Loosen lug nuts with a socket set while the vehicle is on the ground.
• Raise the vehicle using a jack and secure it with jack stands.
• Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

• Sub-steps:
  • Remove the caliper bolts using a socket set.
  • Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid strain on the brake line.
  • Remove old brake pads from the caliper bracket.
  • Inspect the caliper slides for dirt or damage and clean them if necessary.
  • Place new brake pads into the caliper bracket ensuring they are seated properly.
• Tools Required: Socket set, bungee cord, brake cleaner.

4. Inspect and Replace Brake Rotors (if necessary)

• Sub-steps:
  • Check the surface of the rotors for scoring or wear. Replace if they do not meet manufacturer specifications.
  • If replacement is needed, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
  • Install new rotors, ensuring they are properly aligned and secured.
• Tools Required: Torque wrench, socket set.

5. Reassemble Components

• Sub-steps:
  • Reinstall the caliper over the new brake pads and secure it with the caliper bolts.
  • Reattach the wheel and hand-tighten the lug nuts.
  • Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specifications using a torque wrench.
• Safety Warnings: Ensure the vehicle is secure on jack stands before working underneath.
