Solution
1. Preparation
  • Gather tools and parts.
  • Ensure the vehicle is parked on a flat surface.
  • Engage the parking brake and place wheel chocks behind the rear wheels.
2. Inspect and Replace Brake Components
  1. Remove Wheel

    • Use a jack to lift the front of the vehicle and secure it with jack stands.
    • Remove the lug nuts using a socket set and take off the front wheel.
  2. Inspect Brake Pads and Rotors

    • Visually inspect the brake pads for uneven wear. Replace if one side is significantly more worn than the other.
    • Check the rotor for scoring or warping. Replace the rotor if necessary.
  3. Examine Brake Caliper

    • Ensure the caliper is functioning properly and not seized.
    • If the caliper is sticking, remove it by unbolting it from the bracket using a socket set.
    • Clean the caliper slide pins and apply brake grease before reinstallation. Replace the caliper if it’s damaged.
3. Check Suspension Components
  1. Inspect Suspension
    • Look for any damaged or worn control arms, bushings, or struts.
    • Replace any faulty components as necessary.
4. Wheel Alignment
  • After replacing any brake or suspension components, perform a wheel alignment to ensure proper tracking.
5. Reassemble
  • Reinstall the brake caliper, ensuring that it is securely bolted.
  • Reinstall the wheel and hand-tighten the lug nuts.
  • Lower the vehicle and torque the lug nuts to the manufacturer’s specification (typically around 80-100 ft-lbs).
