Component
Brakes
Repair Time
2-4 hours

Safety Warnings

  • ⚠Ensure the vehicle is securely lifted before working underneath.
  • ⚠Always wear safety glasses and gloves when handling brake components.

Symptoms

  • •Steering wheel shakes or vibrates when braking
  • •Vehicle pulls to one side during braking
  • •Brake pedal pulsates or feels uneven
  • •Increased stopping distance
  • •Possible noise from the brakes (squeaking, grinding)

Diagnostic Steps

  1. 1Inspect brake components visually for wear or damage, including pads and rotors.
  2. 2Check rotor thickness with a caliper to ensure they are within specifications.
  3. 3Use a wheel balancer to verify that all wheels are balanced correctly.
  4. 4Perform a test drive to confirm the presence and conditions of the shaking.
  5. 5Inspect suspension components (control arms, ball joints, bushings) for wear or damage.
  6. 6Check alignment settings to ensure proper vehicle handling.

Solution

Solution

1. Preparation

  • Gather tools and parts needed for the repair.
  • Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
  • Disconnect the battery if electrical components are involved.

2. Inspect and Replace Brake Pads and Rotors

  1. Lift the Vehicle:

    • Use a jack to lift the front or rear (depending on which brakes are being serviced) and secure it with jack stands.
  2. Remove Wheels:

    • Use a lug wrench to remove the lug nuts and take off the wheels.
  3. Remove Brake Caliper:

    • Use a socket set to remove bolts securing the brake caliper.
    • Support the caliper with a bungee cord or similar to avoid straining the brake line.
  4. Inspect and Replace Brake Pads:

    • Remove old brake pads from the caliper bracket.
    • Compare new pads with old for wear.
    • Install new brake pads into the caliper bracket.
  5. Inspect and Replace Brake Rotors:

    • Remove the old rotor by unscrewing any retaining screws or clips.
    • Clean the hub surface to ensure the new rotor sits flat.
    • Install the new rotor, ensuring it is secure.
  6. Reassemble Caliper and Wheel:

    • Reattach the caliper over the new pads and tighten bolts to manufacturer torque specifications.
    • Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even pressure.

3. Check Suspension and Alignment

  1. Inspect Suspension Components:

    • Visually check for any worn or damaged parts in the suspension system.
    • Replace any parts that show signs of wear.
  2. Perform Wheel Alignment:

    • Use an alignment machine to adjust the alignment according to manufacturer specifications.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
  • Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

  • •Follow the manufacturer's recommended maintenance schedule
  • •Address warning signs early before they develop into major issues
  • •Use quality parts and fluids recommended for your vehicle
  • •Keep detailed records of all repairs and maintenance

Tools & Equipment Required
