The vacuum brake booster check valve is part of the brake booster, and plays an essential role in brake system operation. It is a one-way valve that allows air to be sucked out of the booster, but does not allow air to enter it. This is a safety solution to ensure that if the engine is turned off, or if frequent stops or pedal presses are required, the brakes still operate. Its capacity ensures that you have enough boost for several brake applications. The vacuum brake booster check valve connects the vacuum hose from the engine to the body of the brake booster.
Many different issues can create problems with the braking system, including air in the lines, dirty/burned brake fluid, and more. If you suspect a vacuum brake booster check valve issue, have one of our expert mechanics diagnose it.
While a leak in the vacuum brake booster check valve will not eliminate your ability to stop, it will make braking much more difficult and increase your stopping distance. It should be repaired as soon as possible.
