Because I do not know question about PS Fluid?

[Ken1]

Earlier this year when I was searching for problems ( F350 in Sig) with power steering unit (later replaced) someone commented that the PS fluid also is pumped thru the brake booster?
When I was having PS unit problems the entire PS fluid had metal fines in system. The PS unit was replaced but even after 4+ months of driving I still fine metal fines attached to magnet I have in PS reservoir.
The question is could I also have fines flowing thru the brake booster?

Thanks for any help

Yes, those FINES would be flowing thru the booster too. But as long as your magnet is catching the fines..? Not to worry. As long as they are FINES, not Chips or Shavings. The magnet is doing its work. If the fines are like Muddy Dust (?) it's normal pump wear. (like the stuff you find when you flush & clean a Rear Dif., Normal wear)

JMO but bigger tires, wheels and changing suspension geometry [can] have an effect on speeding up Normal Wear too.. asking more from the OEM pump than it's design limits can deliver... in the long term.

Thanks for the reply, I will try to push Ford Tech to replace booster and fluid under warranty.

Thanks

Did thay flush the lines and ps cooler to? If not the whole system could be contaminated with filings.

The Ford Tech replaced the PS unit and removed the reservoir and pumped a small amount to flush. But I attached a magnet to PS Dipstick to catch metal fines. Now 4+ month later still have a metal fine problem.

Thanks for the replies

Yeah I think I'd ***** and go back to them asking WTF? That metal is coming from someplace, and unless the amount your collecting is becoming less and less, you have another wear issue at hand. If what your collecting seems to be trending downward, you're probably okay, but all that means is whoever "flushed" it did a lousy job.
