No breaks
I have 2002 ford f250 with the 7.3, I have no breaks or power steering, this happened d the night after it was negative 15 in Wisconsin. I have the bleed the breaks and the booster is only about a year old. Any ideas what it could be. The ABS light comes on before starting then I turn it on and it goes away it does not come on when I press the breaks either. Please give me any ideas I would like to have the truck fixed before school starts again

Both the booster and steering are powered from the power steering pump, so logic says your problem likely lies there. Check that the belt is tight and the pully is clean so no slipping is taking place. Check the reservoir is full and that fluid is circulating while the engine is running. If you think the issue is related to the low temps check that the fluid isn't milky w/ condensate. It's possible the pump has worn out, truthfully they weren't really up to the task when everything was new off the line. If it does turn out to be the pump I don't recommend a parts store reman they don't have a very good track record.

Several years ago and about 6 months after replacing my steering gear again, we had a cold spell come through. The brakes were not working properly as well as the steering. They were not "breaking", but the braking was not great either.
See video below...
Turns out there was air in the power steering/hydroboost system and 3/4 of a gallon of ATF flushed it out. The only thing I can figure is that the small amount of air was not a problem until the temperature dropped below 10°. It then either condensed or created moisture in the system causing abnormal behavior. Again, the truck was roadworthy and fully operational the entire 6 months prior.
Good luck and just be careful not to break anything while you are trying to fix your brakes.

Brake fluid is hygroscopic, meaning that it absorbs water right out of the atmosphere. If it was fine before and now at 15 below, they're not, my first thought is that they needed flushing before the cold weather hit and now what water was in the system is now frozen. I've never had to deal with arctic cold before, but I'm guessing the truck needs to be brought into a heated garage for a day, then a complete brake fluid flush/replacement needs to be done to it. Then you'll have your brakes back.

Kwik, he also has no power steering. This points to an issue with the pump which supplies both.
The others have already covered how to look into the pump side. I just want to add, this system does NOT use power steering fluid. It takes ATF. There’s also a good video on YouTube about how to flush the system. I think my search was hydroboost flush or such. I’ll see if I can find it.
Edit: this isn’t the video I was thinking of (and used for my flush) but it looked pretty good.

The vacuum pump has absolutely nothing to do with brakes or steering on these 7.3 powerstroke trucks. It's only function is to provide vacuum for the HVAC ductwork actuators and if equipped four wheel drive automatic hubs.

The pump is the lower pulley on the driver's side below the alternator. Assuming you got the more common single alternator belt drive configuration that is.

thank you I did figure it out and it was the power steering pump. I took it out and out would barely spin on it’s own. Just ordered the part for it and should be here this coming week
