You have what they call a hydro boost system, the power steering pump give power steering assist, and give power brakes, so if your power steering hose looses fluid you get not power steering and no power brakes, So check the power steering hose for leaks if there is no leaks replace the powersteering pump
Look and if you have the hydroboost system on your vehicle..If so the power steering pump control the brake assit and the power steering..Then if you have that system,, check the power steering fluid level ..If its not low then you might have a bad powersteering pump..The hydroboost is located right behind the master cylinder..It has hoses coming off of it and circles back around to the pump..
If you have the hydroboost system..The powersteering pump gives you power assist while you steer..And it also gives you power assist to your brakes..When you have trouble with the power steering pump,,you lose your assist in your steering and your brakes..Youll get a hard brake pedal feel and it will be hard to steer as well
Hello hummelsautob. Changing the power steering cooler can't allow air into the brake system. Two different fluid systems. Your F250 has it's brake assist powered by the power steering pump. Instead of using a vacuum assist it uses the hydraulic power from the pump. When refilling your pump you have gotten air mixed in with the fluid. This turns it into a consistency something like whipped cream. When in this state it isn't effective. Let it sit for a couple hours and let the air bubble out of the fluid. Recheck your level after this as it will drop. This will make your brakes feel normal again. Just a note on adding fluid to an empty power steering pump. Add fluid to the reservoir but not to the top, turn the steering wheel back and forth slowly with the engine off. This will keep the fluid from foaming.
Replace the ps pump, brake fluid is not a lubricant, your pump is scored, raise the van, block it, remove the sheild, belt and right axle, and remove the pump, you will have to flush the system with 4-5 litres of PS fliud only. GOOD LUCK, RDJRP
take the bolt out and put some locktite on the thread ,then tighten it up again with the flywheel locked up the best you can ,ie-- with a big screwdriver jammed into the ringear
three things to check the powersteering hose, the pump and the steering rack itself usualy the power steering hose and the steering rack usualy go bad in them
