What is a Power Brake Booster all about?
A brake booster makes it easier to push the brake pedal. It is a vacuum assist system. If the car did not have a brake booster, it would be very hard to push the brake pedal and stop the car. The brake booster is located underneath the hood in the engine compartment, behind the brake master cylinder.
Keep in mind
The most common reason why a brake booster fails is because the master cylinder is leaking. Your mechanic should inspect the master cylinder to ensure there are no leaks.
How it's done:
- Remove/replace power brake booster.
- Check brake fluid level and condition.
- Check complete brake system for any leaks in system.
- Inspect the brake master cylinder.
- Bleed brake fluid system if needed.
If you notice a clear fluid underneath your car or on the wheels, get it inspected as soon as possible. Do not drive the car with brake fluid leaking. It can make the brakes weaker and eventually lead to brake failure.
What common symptoms indicate you may need to replace the Power Brake Booster?
- Very hard, stiff brake pedal.
- Lack of braking power.
- Hissing noise when stepping on the brake pedal.
