Good to hear the SSBC piece is quiet. It must be an updated design, as the older ones where really loud.

I made my own hydroboost kit for my 69 charger. I used a booster off a astro van. It was in excellent shape for $50. I think it was a '98 or a '01, but its been a while so I don't remember. I used a early 90's C3500 master cylinder with a 1" bore. They used an identical looking master cylinder in the dodge rams of similar years but the dodge master cylinders had metric fittings and the chevrolet had english threads. You will have to machine the bracket or make a spacer. If not you will have to modify the hole in your firewall to get the proper alignment. I used a aftermarket clevis and threaded the shaft on the hydroboost. I got the tool to remove the nut on the hydroboost from factory five racing for about $20. I used russell hoses and fittings. Overall I think I spent about $250 for the raw materials and parts. I don't have any drawings or notes anymore, but you can try checking with Ira. He and I were working on our conversions at the same time. The reason I installed it was because I have 4 wheel disc and little vacuum. It works great and can easily lock the wheels.

Edit: I found my old post that give more information on the conversion.

I have wanted to add a hydro-boost brake booster for some time now, but I really dont want to pay the 700-900 for a kit. Has anyone done their own? You can pick up rebuilt boosters for about $120 and possibly just have to fab up a braket or to.

So has anyone done this?



I have the Hydratech kit on my Challenger with a AndyFs Viper front brake kit. When I bought my kit it was less than $500 and the customer service was great. I think you have to purchase through his dealers now since he could not keep up with all the orders and tech support.

The only draw back to hydroboost is pedal feel is not very good.....hard to modulate the brakes. My car stops very well and one has to be careful so not to put your head thru the windshield

Found some other resources out there for this.

I've picked up a 95 Astro unit including the 1-1/4" master cylinder and am in the process of figuring out my own setup thanks to the trail blazing spirit of those that have figure out all the tough details.

I have a 75 Dart originally equipped with vac power brakes. Originaly disc/drub and now converted to disc disc thanks to Dr Diff's cobra conversion. Seems to be the best way for me to get some good power assist to help make the car stop as it should.

I know this is some other A-body owner out there that has made the conversion and I'd sure like to know your approach to mounting the thing and which master cylinder you went with.

I could get a complete Hydroboost Power Brake Unit from a 1984 Caprice with mounting brackets it looks like if the studs could bolt to a B-Body Mopar firewall. Anyone tried?

With a MC from same car it should work with a B Body Disc Brake, or going wrong direction?

The Hydraboost in my '93Sub worked for nearly 200K miles, then failed. I bought a rebuilt one from Advance. Glad I wasn't starting from scratch because the unit and the core charge were BOTH in the neighborhood of $160. Which means if I didn't walk through the door with the old onel, the rebuilt would have cost over $300.

They're made by Bendix.

In my Suburban, the brake feel was excellent. It was very progressive, not like the "on-off switch" feeling of late '60s Mopars.

It's been a few years, but I researched this heavily. A guy on Ebay was selling rebuilt Hydro boosters in a kit which included the mounting bracket and all fasteners. I can't remember if he was selling the adjustable plunger rod. Seems like I had to find that on my own. I bought a new aluminum master cyl. (I think 15/16") (or it might have been over 1") There are kits you can buy for close to $1000, or you can make your own. There are plenty of sites on the web to show you how to do it cheaply. I never found a "high output" power steering pump for a Mopar. I haven't installed mine yet. I may try to use a late model Jeep power steering pump. I was going to put it on my 67 Coronet, but am now going to put it on my Challenger. Seems that every Ford hydro unit had the mounting flanges straight up and down. I don't know how you would mount them easily. GM has horizontal mounting flanges, making it much simpler. The set I have looks very nice, factory brand new looking. It even has the firewall mount pre-attatched to the booster body. Very complete, even with the rubber boot for the rod, nylock nuts and ALL assorted hardware needed. It did NOT come with pump, hoses or Master cyl. Or instructions. Lol, I just looked at the kit to refresh my memory. Sorry. I can't remember the Ebay vendors name. It was a fraction of the price of all those popular pre made "kits" on the market. Only a couple of hundred bucks.

So you can't really use this hydro-boost on a vehicle that has a Vacuum booster because the cam is really lopey, runs 2 canisters AND had vacuum headlights.....right?


Hydro Boost SOLVES low vacuum brake problems caused by big cams. You are using power steering fluid to run your brake system assist INSTEAD of vacuum. You actually remove your vacuum booster and mount the Hydro Boost directly to the firewall. It can give you much needed valve cover clearance.

The pump you want is a mid 80's to late 90's GM 3500 series diesel, it is a Saginaw pump with 2 return lines on the reservoir. Mounts the same as any other sag pump. You also don't need a high output pump, the brakes done use much volume. Tim
