Mechanic needed

Hunt hwy near Gary, Queen Creek AZ

Description

Please note this is in San tan valley. I was told I need spark plugs and engine coils replaced, I had someone else from CL come over and look at the car and he discovered that something way less intense was the issue, but when he left after taking a look my break pedal is extremely hard to push down, I read about it and this a vacuum came loose? I have a 2015 Jeep Grand Cherokee.
