Solution
1. Preparation
  • Gather tools and parts required.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Disconnect the negative battery terminal to prevent any electrical issues.
2. Inspect and Replace the Brake Booster

  • Inspect the Brake Booster:

    • Remove the engine cover if necessary for access.
    • Visually inspect the brake booster for any signs of damage or fluid leaks.

  • Replace the Brake Booster (if defective):

    1. Disconnect the vacuum line and any electrical connectors from the brake booster.
    2. Remove the nuts securing the brake booster to the firewall using a socket set.
    3. Carefully pull the brake booster away from the firewall and remove the pushrod from the brake pedal.
    4. Install the new brake booster by reversing the removal steps.
    5. Reconnect the vacuum line and electrical connectors.
3. Refill and Bleed Brake System

  • Refill Brake Fluid:

    • Check brake fluid level and top off with the appropriate type (DOT 3 or DOT 4 as specified).

  • Bleed the Brake System:

    1. Using a brake bleeder kit, start at the furthest wheel from the master cylinder (usually the passenger rear).
    2. Have an assistant pump the brake pedal while you open and close the bleeder valve to remove air from the system.
    3. Repeat on each wheel until all air is purged.
4. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Start the vehicle and check the brake pedal feel.
  • Take the vehicle for a test drive to ensure the brakes function properly.
