Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety while working on the braking system.

Tools Required:

  • Jack and jack stands
  • Socket set
  • Torque wrench
  • Brake cleaner
  • OBD-II scanner
  • Multimeter (if necessary)
2. Inspect and Replace Brake Pads

  1. Remove Wheel:

    • Loosen lug nuts, then lift the vehicle using a jack and secure it with jack stands.
    • Remove the wheel to access the brake components.

  2. Examine Brake Pads:

    • Inspect the pads for wear; they should be at least 3mm thick.
    • If worn unevenly, replace the brake pads.

  3. Install New Brake Pads:

    • Remove the caliper bolts and slide off the caliper.
    • Replace the old pads with new ones, ensuring they fit securely.
    • Reinstall the caliper and torque the caliper bolts to the manufacturer's specifications.
3. Inspect and Replace Brake Rotors

  1. Check for Warping:

    • Use a dial indicator to measure rotor runout; anything above 0.002 inches indicates warping.
    • If warped, the rotors will need to be resurfaced or replaced.

  2. Remove Rotors:

    • Remove the caliper and bracket to access the rotor.
    • Unscrew the rotor from the hub and replace it with a new one if necessary.

  3. Reassemble Components:

    • Reinstall the caliper bracket and caliper.
    • Torque all bolts to the specified values.
4. Brake Fluid Check

  1. Inspect Brake Fluid:

    • Check the brake fluid reservoir for proper levels.
    • If low or contaminated, flush the brake system and refill with the manufacturer's recommended brake fluid.

  2. Bleed Brakes:

    • Bleed the brake lines to remove air and ensure proper pressure in the system.
