Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and securely supported with jack stands.
  • Wear safety gloves and goggles.
2. Check Brake Fluid and Lines
  • Remove the master cylinder reservoir cap and check the brake fluid level.
  • If low, top off with the manufacturer's recommended brake fluid type.
  • Inspect brake lines from the master cylinder to the calipers for leaks or damage.
3. Inspect and Test Brake Booster
  • Locate the brake booster and visually inspect for cracks or damage.
  • Connect a vacuum gauge to the brake booster vacuum line.
  • Start the engine and observe the gauge. It should read a stable vacuum (usually around 18-20 inHg).
  • If vacuum is low, inspect the vacuum line for blockages or leaks.
4. Replace Brake Booster (if faulty)
  • Disconnect the negative battery terminal.
  • Remove the vacuum line from the brake booster.
  • Detach the master cylinder from the brake booster (remove bolts and gently pull).
  • Remove the brake booster mounting nuts and carefully remove the booster from the firewall.
  • Install the new brake booster by reversing the removal steps, ensuring all connections are secure.
5. Bleed the Brake System
  • Fill the master cylinder with brake fluid.
  • Bleed the brake system using a helper or a brake bleeder kit, starting from the farthest wheel from the master cylinder and working towards the closest.
