1991 Bounder/454/p30/31'
I had a squeek in my brakes when applied so I replaced all four calipers-the rubber hoses-rear disc's and pumped 3 quarts of fresh fluid into system-Brakes haven't got any better but squeek is gone-If I hold pressure on brake pedal it stays up and does't bleed down so I assume Master cyl is not leaking by--BUT --I have to push the brake real hard and I can stop quickly if I need to but realy have to push hard-Is there some kind of a booster that could not be working???-This brake system doesn't have a vacum booster like a car but really don't know how the booster would work or even where it is-Rich

You could have a hydro boost which works off the powering steering pump. Hydro boost is located under driver's seat area.

May not be helpful but does give you the name of the system to search on.

Did you bleed the sys sound like it just needs to be bled?

Scott we bleed the system quite a few times and now if I pump the peddle it gets no harder or higher so we have ruled more bleeding out--I just took her on a shake down run on the Hwy and it seems I got the same amount of brake that I had before I started--MAYBE it is as good as it gets-Maybe the newer Rigs just have better brakes-When we get back from FL I will talk to couple mechanics and get their opinion after they drive it---Rich

Dose the reservoir ever goes down while you are pumping or dose it stays full.

I'd want to check this too. Bad/loose power steering belt, low on fluid, or partially plugged screen could all have something to do with this. The Hydro-boost has a large plastic screen and several 'O' rings. The screen could be plugged or an 'O' ring could have broken.
Tip off that it might be a power steering pump issue would be squealing when you turn the steering wheel full left or right.

Yes the reservoir does go down as we bleed the brakes but we kept checking to make sure we didn't run it dry-All the belts are tight-I pretty much come to the conclusion it is was it is and to live with it the other MH I drove was a 2005 and mine is 1991 so even though I got 4 wheel disc brakes they just aren't as good as newer models-Thanks Rich
