Brake Booster Check Valve | Bronco | F100/150/250

The Brake Booster Check valve is a fairly obscure item, its sits on the side of the brake booster and doesn't seem to do much.

However it is an important component and its job is to allow vacuum to draw from the brake booster but not allow air to return. When it fails, its bad, so you will want to ensure it is in optimum condition.

In fact, just play it safe and replace this as a matter of standard maintenance.
