No steering/brake pressure.

Had the Humvee sit over the winter. Mostly anyways. Had it out at Xmas and I’m once in Feb and a decent drive in March. No issues. Just started it and zero steering pressure or brake pressure.

Fluid is good level and condition,

Any quirks to these or did the pump just go bad?

Thanks guys.

I just revved it up decently and now it’s back…..for how long? I guess a pump is in order probably.

No quarks or tricks there, if it has fluid and the belt is good condition and spinning the pulley the correct direction, then all should be working. I have seen the pump shaft break inside the housing and the pulley just free wheels. Other wise the pump element can go bad and there is a valve in the pump that can be stuck and bypassing fluid internallly. Can you see the oil churning around in the pump when its running?

So revved it up and now it’s perfect. Shut down and totally normal on restart.
I suspect pump is probably going?
Did not check for fluid churning, but fluid, belts, pulley are indeed all good.

Most likely you have an air leak somewhere that allowed the fluid to leak out of the pump. Once you revived the engine, you got fluid circulating again. Remember that steering fluid pressure also controls the brakes.

I have no fluid leaks tho…..the fluid is less then a year old as my fan failed last year.

It’s parked on clean concrete floor and no drips.
Possible a vane was stuck?

I’ll leave it for a week and try again maybe. I just found it odd how it came back. Lmao. Well maybe it’s actually par for the course

Yes, I had no hydro boost either obviously.
