I noticed a raised bump on my hood this morning, almost like the hood was closed with a tool left in there (but it wasn't). I'm fairly sure that this bump occurred with the hood closed. On the underside of the hood where the raised bump is, the left-over adhesive is worn away and white, and the highest point in that metal line is what is making contact there. You can see on the metal line, right near the red cap, where it is shiny - that is where the line is the most raised and where it is contacting the underside of the hood. Is it possible that that like could raise up with enough leverage to make a small bump? Are are some pics.

that is the hard line for your rear brakes

it might be bent slightly upwards but it still shouldnt be getting close to the hood, has the hood ever been repositioned on the car ?

The brake line doesn't look that much higher than the reservoir or the booster, is it?

The wear on the hood looks like it's from continued vibration and not a single blunt impact.

would the firewall crack pivot from the top?

you might have someone push the brake and clutch pedal down to check for movement.

That does look like an abrasion instead of an impact. I've left tools on the engine and experienced impacts.

I can say that I've been successful repairing impact injuries using a rubber mallet and a short section of 2x4 stud. If you're careful the damage can be completely removed.
