Solution
1. Preparation
  • Gather tools and parts.
  • Ensure the vehicle is on a flat surface and securely lifted with jack stands.
  • Wear safety goggles and gloves.
2. Inspect and Refill Brake Fluid
  • Remove the cap from the brake fluid reservoir.
  • Check the fluid level; if it's low, add the appropriate brake fluid (DOT 3 or DOT 4).
  • Securely replace the cap.
3. Check for Leaks
  • Visually inspect all brake lines, calipers, and wheel cylinders for signs of fluid leaks.
  • If leaks are found, replace damaged brake lines or components.
4. Bleed the Brake System
  • Attach a brake bleeder kit to the brake caliper.
  • Have an assistant press the brake pedal while you open the bleeder valve to release air.
  • Close the valve before the pedal is fully depressed to prevent air from re-entering.
  • Repeat this process until fluid runs clear without bubbles.
  • Ensure to repeat this for all four wheels.
5. Inspect Brake Pads and Rotors
  • Remove the wheel to access the brake components.
  • Check the thickness of the brake pads; replace if they are below the manufacturer's minimum specification.
  • Inspect the rotors for warping or excessive wear, and replace if necessary.
6. Test Brake Booster
  • With the engine off, press the brake pedal several times to deplete vacuum.
  • Start the engine while pressing the brake pedal. If the pedal drops slightly, the booster is functioning; if not, the booster may need replacement.
