If you move the pushrod you will get more stroke Imagine a teeter totter the further you get from the pivot point the more travel,same with your pedal. Further from the pivot point is more movement. Get someone with a power brake truck to measure how far from the pivot point their pushrod is located,compare to yours. Normall a power brake vehicle will have the pushorod further from the pivot point than a non power car.I'd check it for you but can't until Thursday. Also there is a pushrod in the booster, that should have adjustment checked,there should be .020 clearance between the end of the pushrod and the master. It takes a special tool to check it,but you can do it without the tool,just not as easy. Google it. And you still don't understand parked vs. Not parked or I don't understand what you are trying to tell me. I'm not concerned about engine running or not. What I was talking about was it is possible to have a good pedal in a vehicle that is parked,but not have a good pedal if the truck has rolled at all,loose wheel bearings will allow the rotor to push the pads in,just like you had pushed them in to change them,so will warped rotors,so in either case it is possible to end up with a pedal you have to pump if the vehicle has moved. That is why I kept asking can you get a good pedal parked
