Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a flat surface and engage the parking brake.
  • Disconnect the battery to prevent electrical issues.
2. Remove Wheel Assembly
  • Sub-step 1: Loosen the lug nuts on the wheel associated with the braking issue.
  • Sub-step 2: Raise the vehicle using a jack and secure it with jack stands.
  • Sub-step 3: Remove the wheel to access the brake components.
3. Inspect and Replace Brake Pads
  • Sub-step 1: Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
  • Sub-step 2: Inspect the brake pads for thickness; replace if they are less than 3 mm.
  • Sub-step 3: If replacing, remove the old pads and install new ones, ensuring they are properly seated.
4. Inspect and Replace Brake Rotors
  • Sub-step 1: Check the rotors for warping or scoring; replace if necessary.
  • Sub-step 2: If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and slide it off the hub.
  • Sub-step 3: Install the new rotor, ensuring it is clean and properly aligned.
5. Reassemble and Test
  • Sub-step 1: Reattach the brake caliper and secure it with the bolts to the specified torque (typically around 30-40 Nm).
  • Sub-step 2: Reinstall the wheel and tighten lug nuts in a crisscross pattern to the manufacturer's specifications.
  • Sub-step 3: Lower the vehicle and reconnect the battery.
