What Happened
Your vehicle's brake booster vacuum supply hose may swell over time and lose its grip on the intake manifold. This could cause the hose to detach during an engine backfire.
Risk if Unfixed
If the hose detaches, you may experience reduced braking power, which could lead to a crash, especially if you have to press the brake pedal harder to stop your vehicle.
Free Fix
You should contact your local Ford dealership to schedule a free repair, which will involve replacing the rubber hose on the brake booster vacuum supply tube assembly.
