Has anyone on here replaced their hydroboost? The reason I ask is that on my Excursion, the brake pedal doesn't feel as firm as before, I replaced the power steering pump since it was making noise, and that helped for awhile but now is not as firm. Fairly intermittent..
Usually when a hydro boost unit goes out the pedal will be hard as a rock, just like a vacuum booster. I would look at pads or hoses maybe. Air in the line will doe that as well. Bleed first me thinks.
