Almost everytime I start my truck the brake pedal jumps out at my foot right when its just fired up. Is this normal or not?

If you have your foot on pedal on startup, yes it is normal to jump.

Normal as Numbnuts said.

its just the hydro-boost system suddenly becoming pressurized by the engine turning the pump...normal as everyone said!

Normal as Numbnuts said.

Normal, yes. But somehow, the above statement just seems ... weird.
