Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
  • Gather necessary tools and parts.
2. Inspect and Replace Brake Fluid
  • Sub-steps:
    1. Open the master cylinder reservoir cap.
    2. Remove any contaminated brake fluid using a turkey baster or fluid siphon.
    3. Refill with fresh brake fluid that meets manufacturer specifications (e.g., DOT 3 or DOT 4).
    4. Replace the reservoir cap securely.
  • Tools Required: Turkey baster or fluid siphon, funnel.
3. Inspect and Replace Brake Lines
  • Sub-steps:
    1. Locate and inspect all brake lines for leaks or damage.
    2. If leaks are found, use a line wrench to disconnect the affected brake line.
    3. Measure and cut a new brake line to the appropriate length.
    4. Install the new brake line, ensuring all fittings are tight and secure.
    5. Bleed the brake system to remove air.
  • Tools Required: Line wrench, pipe cutter, brake line flaring tool, brake bleeder kit.
4. Inspect and Replace Brake Pads and Rotors
  • Sub-steps:
    1. Remove the wheel to access the brake caliper.
    2. Unbolt the caliper and slide it off the rotor.
    3. Remove the old brake pads from the caliper bracket.
    4. Inspect the rotor for damage; replace if warped or worn beyond specifications.
    5. Install new brake pads and reassemble the caliper over the rotor.
  • Tools Required: Socket set, torque wrench, brake cleaner.
5. Test the Brake Booster
  • Sub-steps:
    1. With the engine off, pump the brake pedal several times to deplete the booster.
    2. Start the engine and press the brake pedal; it should feel firm and drop slightly.
    3. If it doesn’t, inspect the vacuum line and the booster for faults.
  • Safety Warnings: Ensure the vehicle is in park and the engine is running during tests.
