I think we all might have a leaking(minor to major) hydo boost.
I just found out mine has been leaking a little for awhile now
I am going to replace as soon as I can

Low/soft Pedal.. hydra boost systems

Doing a 2001 excursion ... aftermarket shows only one master cylinder.. motor craft shows two 1 with hyraboost BRMC26 and one with vacuum booster BRMC27. this is stroked differently .. try the correct master cylinder.

just found out the hard way

I can't live with *****ty brakes any longer so I'm ordering both the Hydroboost and the Master cylinder, I can get both for under $300 and it looks super easy to install. I'll post by the middle of next week on results here goes nothing ........
Not trying to bust anyone's *****. But I'm researching soft breaks and thinking it's a master cylinder. I see no fix reported

I was told by a member on here a while ago Ford had an issue with our master cylinders where the internal piston would over travel and force fluid past the cruise control cutoff sensor. Ford blamed the sensor for the fluid leak (and fires) but the real culprit was the MC. I have noticed on my truck the hotter the outside temps get the weaker the brakes and I get a progressively louder squeak/squish noise when the pedal is pressed. Hydroboost is also leaking a small amount.

So if the hydroboost only provides power brakes like a vacuum booster then the pressure and efficiency lies in the MC. If it is overtraveling causing leaks then maybe the pressures are off internally (+/-) causing poor performance. As soon as I have some money I am going to replace both units on my truck this summer.

Ok i'm guessing no one has heard anything about this. I'll chime in because i am about to put my 3RD set of rear brake calipers on my truck in the past year. Not sure why i keep going through them but i have the same symptoms and then eventually one of them will start dragging followed by the other. Just wondering if maybe this problem is related to what you guys are having going on?

Have you replaced the hoses? Not the lines, the hoses.

I'm happy to say mine was as simple as replacing the MC. I read through a few threads here on the brake issues and the one issue that couldn't get me past the MC is that with the truck not running, I could push the pedal slowly and it kept sinking.
