Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Put on safety goggles and gloves.
2. Inspect and Replace Brake Fluid
  • Sub-steps:
    1. Locate the master cylinder reservoir and check the fluid level.
    2. If low, top up with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
    3. If the fluid is contaminated or dark, proceed to replace it.
  • Tools Required: Brake fluid, funnel.
3. Check for Leaks and Repair
  • Sub-steps:
    1. Inspect brake lines and hoses for any signs of wear or leaks.
    2. If leaks are found, replace damaged brake lines or hoses. Use appropriate fittings and seals.
    3. Check the brake calipers and wheel cylinders for leaks; replace if necessary.
  • Tools Required: Wrench set, brake line tools.
4. Bleed the Brake System
  • Sub-steps:
    1. Start at the wheel farthest from the master cylinder (usually the rear passenger side).
    2. Attach a clear tube to the bleeder valve and submerge the other end in a container with brake fluid.
    3. Have an assistant press the brake pedal and hold it down.
    4. Open the bleeder valve to release air and fluid, then close it before releasing the pedal.
    5. Repeat until no air bubbles are present, then move to the next wheel in order (rear driver, front passenger, front driver).
  • Tools Required: Bleeder kit, clear tubing.
5. Verify Brake Booster Functionality
  • Sub-steps:
    1. With the vehicle off, pump the brake pedal a few times until it feels firm.
    2. Hold the pedal down and start the engine. If the pedal sinks slightly, the brake booster is functioning correctly.
  • Tools Required: None.
