Solution
1. Preparation
  • Gather tools and equipment: jack, jack stands, lug wrench, torque wrench, brake cleaner, and a runout gauge.
  • Ensure the vehicle is parked on a flat surface and engage the parking brake.
  • Disconnect the battery if working on electrical components.
2. Inspect and Replace Brake Rotors
  1. Lift the Vehicle:

    • Use a jack to lift the front or rear of the vehicle and secure it on jack stands.
    • Remove the wheel using a lug wrench.
  2. Check Rotor Condition:

    • Use a runout gauge to measure rotor warping.
    • If rotors exceed manufacturer specifications (typically 0.002 inches), they need to be replaced.
  3. Remove Brake Caliper:

    • Unbolt the caliper from its bracket and hang it using a bungee cord to avoid putting stress on the brake line.
    • Remove the rotor from the hub.
  4. Install New Rotors:

    • Clean the hub surface and install the new rotor.
    • Reattach the brake caliper, ensuring it is securely bolted.
  5. Reassemble Wheel:

    • Place the wheel back and hand-tighten the lug nuts.
3. Inspect and Replace Brake Pads
  1. Remove Brake Pads:

    • If the pads are worn unevenly or below the minimum thickness, remove them from the caliper bracket.
  2. Install New Brake Pads:

    • Apply brake grease to the backing plates of new pads to prevent noise.
    • Reinstall the pads into the caliper bracket.
  3. Reassemble Caliper and Wheel:

    • Reattach the caliper over the new pads.
    • Tighten the caliper bolts to the manufacturer’s torque specifications.
    • Finish by tightening the lug nuts in a star pattern.
4. Suspension Inspection and Repair
  1. Check Suspension Components:

    • Inspect control arms, tie rods, and bushings for wear. Replace any damaged parts.
  2. Alignment:

    • After replacing brake components and any worn suspension parts, perform a wheel alignment.
