Symptoms
  • Shaking or vibration felt in the steering wheel or brake pedal when braking.
  • Possible noise from the braking system (squeaking or grinding).
  • Reduced braking performance or longer stopping distances.
  • Possible pulling to one side when braking.
Diagnostic Steps

  1. Visual Inspection:

    • Inspect the brake pads and rotors through the wheel spokes for any visible wear or damage.
    • Check for uneven wear on the rotors or pads.
    • Look for any signs of brake fluid leakage.

  2. Scan for Error Codes:

    • Use an OBD-II scanner to check if any brake-specific error codes are present in the vehicle's computer.

  3. Check Brake Components:

    • Verify that the brake calipers are functioning properly and not sticking.
    • Inspect the brake lines for any signs of wear or damage.

  4. Brake Rotor Condition:

    • Use a dial indicator or micrometer to measure the runout on the brake rotors. Excessive runout can cause vibrations.

  5. Tire Condition:

    • Check tire balance and alignment. Uneven tire wear can also cause shaking during braking.
Repair Instructions

If Brake Rotors are Warped or Damaged:

  1. Tools Required:

    • Jack and jack stands
    • Tire iron
    • Socket set (including a torque wrench)
    • Brake caliper tool
    • Brake cleaner
    • New brake rotors and pads

  2. Procedure:

    • Raise the Vehicle:
      • Use the jack to lift the front or rear of the vehicle and secure it on jack stands.
    • Remove Wheels:
      • Loosen the lug nuts, remove the wheels, and set them aside.
    • Remove Brake Calipers:
      • Use a socket set to remove the caliper bolts and carefully hang the caliper (do not let it dangle on the brake line).
    • Remove Brake Rotors:
      • Remove the rotor. If it’s stuck, gently tap it with a rubber mallet.
    • Install New Rotors:
      • Place the new rotor onto the hub, ensuring it is seated properly.
    • Reinstall Calipers and Pads:
      • Install new brake pads in the caliper bracket, compress the caliper piston if necessary, and reinstall the caliper.
    • Reinstall Wheels:
      • Put the wheels back on and hand-tighten the lug nuts.
    • Lower the Vehicle:
      • Remove the jack stands and lower the vehicle to the ground.
    • Torque Lug Nuts:
      • Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually around 80-100 lb-ft).

  3. Estimated Time for Repair:

    • Approximately 1.5 to 2 hours.
Safety Warnings
  • Always wear safety glasses and gloves when working on your vehicle.
  • Ensure the vehicle is securely supported before working underneath it.
  • Be cautious of hot brake components after driving.
