What can fail
Corrosion can damage the brake booster, making the brake pedal harder to press and increasing stopping distance. In severe cases, the booster may separate, causing complete brake failure.
What the fix does
The dealer will remove the brake booster sleeve and inspect for damage. If needed, parts will be replaced. You may need a re-inspection within two years.
