How do you test Hydro Boost on a truck?

I have hydro boost in my 2005. I fing know if the test procedure is the same, but for mine they say to **** the truck off, pump the pedal 5 times to release the pressure built up, then hold you foot on the brake pedal and start the truck. If it is working properly it should push the pedal up against your foot when you start the truck.

What does it mean when your Hydro Boost doesn’t work?

If the pump never whines, or the engine never reacts to the load of the pump, suspect a bad pump or slipping belt. While not a perfect test, it is an indicator of a problem.
