Solution
1. Preparation
  • Tools Required: Socket set, brake fluid, wrench set, OBD-II scanner.
  • Ensure the vehicle is parked on a level surface and turn off the ignition.
  • Engage the parking brake for added safety.
2. Check and Replenish Brake Fluid
  • Locate the master cylinder reservoir (typically near the driver's side).
  • Remove the cap and inspect the brake fluid level.
  • If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) to the maximum fill line.
3. Inspect Brake Lines and Components
  • Examine all brake lines for signs of wear, corrosion, or leaks.
  • If leaks are found, identify the source and replace the damaged brake line or components accordingly.
  • Check brake calipers and wheel cylinders for leaks or damage.
4. Replace Worn Brake Pads or Rotors
  • If brake pads are worn down to the wear indicators or rotors are warped, replace them.
  • Sub-steps:
    • Lift the vehicle and secure it on jack stands.
    • Remove the wheel to access the brake components.
    • Remove the caliper and bracket (torque specs usually around 25-35 ft-lbs for caliper bolts).
    • Replace the brake pads and, if necessary, the rotors (torque specs usually around 70-90 ft-lbs for rotor bolts).
    • Reassemble in reverse order and ensure proper re-torquing.
5. Bleed the Brake System
  • After any repairs, bleed the brake system to remove air bubbles.
  • Sub-steps:
    • Use a brake bleeder kit or have an assistant press the brake pedal.
    • Starting from the wheel farthest from the master cylinder, open the bleeder valve and let fluid escape until no bubbles are present, then close the valve.
    • Repeat this process for each wheel, moving to the nearest to the master cylinder last.
