The vacuum brake booster check valve is important to your braking system, and acts as a safety feature. Depending on what actually broke, the repairs can range from simple vacuum brake booster check valve replacement to complete brake system repair and replacement. Hopefully you never get to this point, but if you do, safely stop the car, have the vehicle towed back home and contact a mechanic who is certified with brake system inspections and replacement. The worst-case scenario occurs when the vacuum brake booster check valve completely breaks and eventually leads to a brake system failure. As such, when you experience a problem like this in your vehicle, stop driving it as soon as possible and have the entire brake system professionally examined.

In order to remove the air from the brake lines, the brake system will have to be bled. When air enters the brake lines, it typically becomes trapped due to the fact that brakes are hydraulically controlled. This situation calls for an immediate inspection of the brake system. While driving it will feel as if the brake pedal is spongy, however, the brakes will also take longer to stop the vehicle. This causes a reduction of pressure inside the brake lines and can cause the brakes to be applied softly. In this case, the air that is supposed to be removed by the check valve enters the master cylinder and then into the brake lines. Brakes feel spongyĪs the problem with the vacuum brake booster check valve increases, air bubbles will progressively move down the brake lines and to the brakes themselves. The inconsistency of the brake pedal is a warning sign that a potential safety issue exists with the brakes and should immediately be inspected by a certified mechanic. This is due to the excess pressure inside the master cylinder, which the check valve is designed to regulate. Specifically, the pedal goes from smooth and soft to aggressive and very difficult to press down. When the check valve is not working correctly, the operation of the brakes becomes much more difficult. When the vacuum brake booster check valve is working correctly, applying pressure to the brake pedal is easy and very smooth. Remember, these are common warning signs that should be professionally diagnosed by a certified mechanic and properly repaired.

Here are a few of those warning signs so you can determine if a potential problem with your vacuum brake booster check valve exists. Typically the vacuum brake booster check valve is not inspected during routine maintenance, but there are times when this part can show signs of wearing out or that the booster check valve has failed entirely. This part connects the body of the brake booster to the vacuum hose and is a safety solution that still allows the brakes to work – even if the engine is shut off. This protects the brake lines from developing an air bubble which can seriously impact braking performance.

The check valve is designed to suck out air that is trapped in the brake booster without letting additional air enter the cylinder. This includes the brake booster check valve. From time to time, the vacuum brake booster is susceptible to damage or typical wear and tear. This component is common on a variety of consumer cars, trucks and SUVs. It's designed to provide consistent flow of hydraulic brake fluid to the brake master cylinder while increasing brake pressure and helping heavy vehicles stop more easily. Many vehicles employ a vacuum brake booster in order to provide additional power to the braking system.
