Because you have a vacuum leak somewhere in the power brake booster. If you take and plug the hose that goes to your brake booster from the intake manifold the problem will go away. Be carefull, because your braking ability will also be severely compromised. This means that you may have a hard time stoping the vehicle. It is likely that you havea crack in the diaphragm in your booster. I am guesing that you also have a change in idle when you appl the brakes. If this is indeed the problem, you have to change the diaphragm or the whole booster itself.
It might be right under the hood of the truck, or it might be right in the middle/ box part of the truck.
right below the intake gotta take intake off to get it off

If you have a carburetor, there should be a throttle adjustment screw right next to where the throttle cable connects. Additionally, if you have a carburetor on an F250, the truck is likely a 1987 or older. Not absolutely certain, but I believe Ford has been putting fuel injection on all models since at least then.
To adjust the choke on a 1978 350 4 barrel Chevy truck engine, turn the screw on the side of the carburetor. This screw is located in the side of the carburetor. Turning the screw to the right makes the choke open farther. Turn to the left to make the choke open less.
Right behind the carb, down a bit. there is a wire going to the head on the right side. its a cylindrical aluminum part, kinda behind the throttle body.
right on top of the tank its the small black wire
welll u can eat a bannena that always helps me with diaria. just jokin right
It will if that's what it needs and it is done right.
The fuel filter is in the carburetor. if you're facing the engine, hood up, remove the air filter assembly. There's a large bolt in the lower right position of the front of the carburetor a little bit above the carburetor plate. You have to unscrew this bolt to get out the fuel filter. CAUTION: When I did it, the bolt was in cockeyed and it stripped out and cracked the carburetor. I had to jb weld the carb, and jb weld the bolt back in place with no fuel filter replacement. Then I had to run a hose with a removable fuel filter from the fuel pump to the carburetor. Now I can see the fuel filter and replace it readily.
On my 49cc scooter engine the carburetor is found on the engine. The engine is broken down into 3 parts, the part to the left (looking at it) where the air filter is is right next to the carburetor.
