What is the Vacuum Brake Booster Check Valve all about?

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.

Keep in mind:

The vacuum brake booster check valve is not designed to require maintenance, so it will not be inspected during routine services.
Damage to the vacuum hose from the engine can mimic problems with the check valve.

How it's done:

The vacuum brake booster check valve is removed
