Brake booster is it bad

Hi,

Replacing a power brake booster takes a little time, but really isn't too hard to do. I recommend getting a lifetime replacement part so you never have to pay for a new one in the future.

Here are the directions specific to your vehicle. The pics attached below correlate with the directions.
