Anyone have experience with Hydraboost, like the ones installed on mid-70's LTD's, etc? Is there any advantage (assuming you have a car that produces vacuum so you could use a dual diaphram)? They sure look cool. |

I've driven trucks with it, and I have stripped a few Lincolns with it... That help? I find the pedal feels "funny" compared to a vacuum booster. Hard to describe. In my Cougar, I run the dual diaphragm from a 77-79 Ranchero. When I was having my disc brake issues, I could have gone with the hydroboost to up the psi as well, instead of the dual diaphragm. I like the booster for the following reasons 1. Cost.. $90 vs $300 + for a rebuilt (+ that pesky core). 2. Ease of installation 3. Appearance (Kind of hard to hide all those hoses). 4. See #1 5. A single diaphragm gave me 800 PSI at the calipers... the dual gave me 1150. I think hydroboost can give 1300 PSI? I'm not sure. Unless I HAD to run it, vacuum, clearance, etc, I personally, wouldn't. |

The hydraboost (hydroboost) is advertised at more like 2800+ psi pressure, which supposedly makes a considerable difference. However I hear what you are saying, and on that I will start with a dual diaphram rebuilt from a reputable place.

Well I checked rockauto.. They show $150ish for a hydroboost from a 78 Mark V, with a $10 core.. not bad.. but, I didn't see lines there. I'm sure Napaonline.com or someone else has them, but that'll still get the dollar amount up. http://www.hydratechbraking.com/forums/viewtopic.php?t=90&am p;highlight=psi Still a bit there at 2200 psi |

Good reference there. That guy seemed to know what he is talking about. I guess it would be wise to start with a dual diaphram and move up as needed. The switch to hydraulic is no small switch because of lines, etc. Not to mention a standard Ford steering pump may not be up to it.
