Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools and parts required for the repair.
Clean the work area around the brake system.

2. Inspect and Replace Brake Booster

Tools Required: Socket set, wrenches, vacuum gauge, OBD-II scanner.
Sub-steps:
1. Disconnect the negative battery cable to ensure safety.
2. Remove the engine cover if present for easier access to the brake booster.
3. Disconnect the vacuum hose from the brake booster.
4. Detach the master cylinder from the brake booster (remove the fluid lines carefully and cap them to avoid fluid spillage).
5. Unbolt the brake booster from the firewall (typically 3-4 bolts) and remove it from the vehicle.
6. Compare the old brake booster with the new part to ensure correct fitment.
7. Install the new brake booster by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.

3. Brake System Bleeding

After replacing the brake booster:
1. Reconnect the master cylinder and vacuum hose.
2. Refill brake fluid to the appropriate level.
3. Bleed the brake system to remove any air bubbles (start from the wheel farthest from the master cylinder).
4. Check brake pedal feel and ensure proper functioning.
