It’s great that you noticed your brakes aren’t working as they should. They’re an important part of keeping you safe! Since they are an integral part of your car, it’s best to have a mechanic fix a brake booster.
These are the steps a mechanic will take to fix your car’s brake booster:
  1. Locate the brake booster on the driver’s side, mounted to the firewall.
  2. Remove master cylinder from the outside of the booster.
  3. Remove hose clamp to disconnect the vacuum supply line.
  4. Disconnect booster pushrod away from the brake pedal and remove fasteners.
  5. Remove the booster.
  6. Install new a booster.
  7. Replace fasteners to secure the new booster in place.
  8. Reconnect pushrod and vacuum hose, and reinstall the master cylinder.
A mechanic will also do a general inspection to ensure there aren’t any other issues with your brakes or car.
