Solution

1. Preparation

• Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, OBD-II scanner.
• Raise the vehicle using a jack and secure it with jack stands.
• Remove the rear wheels using a lug wrench.

2. Inspect and Replace Brake Pads

• Sub-steps:
  1. Remove the caliper bolts using a socket set.
  2. Carefully slide the caliper off the rotor and secure it to avoid strain on the brake line.
  3. Remove the old brake pads from the caliper bracket.
  4. Clean the caliper bracket and inspect it for damage.
  5. Install new brake pads, ensuring they are properly seated.
• Safety Warning: Ensure the brake fluid reservoir cap is removed to prevent pressure buildup.

3. Inspect and Replace Brake Rotors (if necessary)

• Sub-steps:
  1. Check the rotor surface for grooves or scoring; replace if necessary.
  2. If replacing, remove the caliper bracket and rotor bolts.
  3. Slide the old rotor off the hub and clean the hub surface.
  4. Install the new rotor and tighten the rotor bolts to the manufacturer’s specifications.
• Torque Specification: Refer to the service manual for the correct torque values.

4. Reassemble and Test

• Sub-steps:
  1. Reattach the caliper over the new pads and secure it with bolts.
  2. Reinstall the wheel and hand-tighten the lug nuts.
  3. Lower the vehicle and torque the lug nuts to the specified value.
