hydroboost?
Looking at what its going to take to get my OM617 into my 115, and id like to keep that stock oil filter which the vacuum boost canister hits.

Searching around online, I find a lot of aftermarket hydroboost setups available. What do people think about adapting one of these setups to an MB? Sure would be convenient if I had a wagon engine to put in, then conceivably I could use the SLS pump setup to run the hydroboost brakes

RE: hydroboost?
Yeah, what is hydroboost?

Maybe you can keep the same arrangement, but use a narrower booster. Like a 7 inch dual diaphragm typically found on Street Rods.

Or move the master cylinder.

RE: hydroboost?
I don't know if this will help or not but, I've got a hydro-boost system on my '04 Chevy Avalanche from the factory. I like it. I don't know why they put it on my gasser but, it's there.

I've also seen the system on a 2002 6.0L (Gas) Silverado 1500HD, and 6.6L Duramax pickups.

The hydro-boost system from GM uses the power steering pump to provide hydraulic brake assistance.

RE: hydroboost?
My dads '90 Chev Dually has hydro boost. They general put it on larger work trucks just because it provides MUCH more braking power and will provide more braking assist after the engine is shut off. Also much more compact in size.

RE: hydroboost?
Some of the S-19s had a real small vac booster. Should bolt right in place of yours. Hotrodders used them & A-10s w/ 350s. Sold alot of them while in auto salvage.

I removed the factory vacuum booster and installed a universal kit from Hydratech, the difference is amazing and the kit was super easy to install!

it looks like a nice product. Did you adapt the MB master cylinder, or did you go with the optional included vette master? Seems to be a pretty decent solution actually.

how did it come on the back side, any issues attaching it to the brake pedal?

also, any pics!? Big Grin

RE: hydroboost?
I measured the bore on the MB master cylinder and used a GM cylinder with the same bore and similar setup. On the backside it came with a yoke that hooked right up, only things I had to do was re-drill the adapter plate to match my firewall and made adapter brake lines with metric on one end and standard on the other. They supplied the correct flare nuts, I bent new lines, flared, installed and bled the brakes and steering system. The lines on the MB pump are standard hydraulic fitting but on the steering box it was not so I had to cut the end off and weld on a JIC fitting which was $20.00 at the local hydraulic shop.

RE: hydroboost?
If I understand Captain America's photo correctly, the hydroboost assist is essentially T-ed into the line going to the power steering gearbox? I'm thinking about doing this after my trans swap so I csn eliminate all vacuum crap completely
-1982 300D Turbo, 280k miles, ALDA apparently maxxed, fram 8038, 12 lbs boost, non-egr manifolds, W/M injection, 4 brake light mod, Gen II w126 front rotors/calipers, 4-speed swap
In the works: A/W IC, adjust pump, turbo rebuild (w/60 trim comp wheel)
-1980 300SD, 110k, project car. Goal is to get it lookin' like it did on the showroom floor (body and interior wise, not necessarily under the hood )
-1974 240D, FRESH PAINT!!!!!!

RE: hydroboost?
The ones I've seen have a high pressure line from the pump to the booster, then from the booster to the steering gear.

very cool , i plan to do this as well, but a quick qauestion

i lost you at the lines on the mb pump ? th power steering pump ? did the kit come with a t fitting to pull high pressure to the booster ?
and you mentioned welding to the box , im assuming the return line fitting ?

RE: hydroboost?
I put a hydroboost on my 85 ford with a diesel. much better. It runs from PS pump to brakes, then brakes have a return and a hiogh pressure out you run to your steering box. have to have 2 return in power steering box. i drilled another return in the stock ford pump and it died so i mounted a chevy pump that had hydroboost factory.

RE: hydroboost?
the v12 adaption in the w123 made me remove the vacumm brakebooster to be able to fit the "downpipe"
how big is these hydrobosters, and how much of a cost is it?
this might be a realy good solution for me!

RE: hydroboost?
They're very thin-look at kmaser's picture. Common on extra large American pickup trucks. Maybe Volvo has a similar part?

Another solution is to remove the booster completely, and use a larger bore master cylinder. Manual brakes were once fairly commong (think 80's pickups and cheap cars). It's all about building up pressure in the lines, you can assist by vacuum, hydraulics, or by displacing a larger amount of fluid.

For what it's worth, I plan to run a large master cylinder with no assist in my little Jeep project. I'll probably use a pickup truck master cylinder.

yeah, but with a turbocharged v12 im not to fond of not having sufficient brakepower Tongue
hydroboost will probably be the way, could one run that with an electric pump?

maybe change out the AC-compressor for another PS-pump to run the hydrboost on?
