Solution

Solution

1. Preparation

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

2. Remove Wheel

  • Use a lug wrench to loosen and remove the lug nuts.
  • Lift the vehicle using a jack and secure it on jack stands.
  • Remove the wheel to access the braking system.

3. Inspect and Replace Brake Rotors

  • Inspection: Use a dial indicator to measure rotor runout; if warping exceeds manufacturer specifications, replace the rotors.
  • Removal: Remove the caliper by unbolting it from the bracket and hang it using a wire to prevent strain on the brake line.
  • Replace: Remove the old rotor by unscrewing any retaining screws or bolts, and slide the new rotor onto the hub. Ensure it is seated properly.

4. Replace Brake Pads

  • Remove the old brake pads from the caliper bracket.
  • Compress the caliper piston using a caliper tool to create space for the new pads.
  • Install new brake pads according to manufacturer specifications, ensuring proper orientation.

5. Reassemble and Test

  • Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
  • Reinstall the wheel and hand-tighten the lug nuts.
  • Lower the vehicle and torque the lug nuts to the specified value.
  • Reconnect the negative battery terminal.
