Solution
1. Preparation
  • Gather necessary tools and parts.
  • Elevate the vehicle using a jack and secure it with jack stands.
  • Ensure the brake fluid reservoir cap is removed before starting.
2. Check Brake Fluid
  • Sub-steps:
    • Remove the cap from the brake fluid reservoir.
    • Inspect the fluid level; it should be above the minimum mark.
    • Check the fluid condition; it should be clear, not dark or contaminated.
  • Tools Required: None
3. Inspect for Leaks
  • Sub-steps:
    • Visually inspect brake lines and hoses for cracks or wetness.
    • Check around brake calipers and wheel cylinders for signs of fluid leakage.
    • Replace any damaged lines or components as necessary.
  • Tools Required: Wrench set, brake line repair kit if needed
4. Test Brake Booster
  • Sub-steps:
    • With the engine off, press the brake pedal several times to deplete the booster vacuum.
    • Start the engine and press the brake pedal; it should feel firmer. If it doesn't, there may be a vacuum leak.
    • Repair or replace the brake booster if a leak is confirmed.
  • Tools Required: Vacuum gauge (optional)
5. Brake Pad and Rotor Inspection
  • Sub-steps:
    • Remove the wheel to access the brake components.
    • Inspect the brake pads for thickness; replace if below 3mm.
    • Check rotors for warping or excessive wear; replace if necessary.
  • Tools Required: Socket set, torque wrench
