Solution
1. Preparation
  • Gather necessary tools and parts. Ensure the vehicle is parked on a level surface, and the engine is off.
  • Tools Required:
    • Socket set
    • Brake fluid
    • Vacuum gauge
    • Brake line wrenches
    • OBD-II scanner
  • Safety Warnings:
    • Always wear safety goggles and gloves.
    • Disconnect the battery before working on electrical components.
2. Check and Refill Brake Fluid
  • Open the hood and locate the brake master cylinder.
  • Inspect the brake fluid level; if low, top it off with the appropriate brake fluid type (DOT 3 or DOT 4).
  • If the fluid is contaminated, proceed to flush the brake system.
3. Inspect Brake Lines and Components
  • Visually inspect all brake lines for cracks, abrasions, or leaks.
  • Check the condition of the brake calipers and ensure they are not leaking fluid.
  • If any leaks are found, replace the damaged components.
4. Test Brake Booster
  • Start the engine and let it idle.
  • Press the brake pedal several times; it should feel soft. If it remains hard, proceed to testing the vacuum.
  • Use a vacuum gauge to check the vacuum at the brake booster. If it’s below specification, inspect the vacuum line for blockages or leaks.
5. Check Master Cylinder
  • Remove the master cylinder from its mount (disconnect brake lines with a line wrench).
  • Inspect for internal wear by checking if the bore is scratched or if the piston seals are damaged.
  • If defective, replace the master cylinder with a new one.
6. Bleed the Brake System
  • After replacing any components, bleed the brake system to remove air.
  • Start with the wheel farthest from the master cylinder, typically the right rear, followed by the left rear, right front, and finally the left front.
  • Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valves.
