i have a souped up olds cutlass with racing cam with power booster vacuum line attached to the carb-sometimes the car seems like it does not want to stop. i was told there is a way to run the vacuum to the power steering giving me much better braking
You are referring to a hydra-boost system of the type they used on diesels, and on the Chevy Astro (because of space requirements). It uses hydraulic pressure to provide boost rather than vacuum, but you'd have to change the whole system. It would be better to use a vacuum reservoir system like the other guy mentioned, much simpler. There are also vacuum pump systems, but they can be kind of expensive.
You are referencing "hydra boost". That would be a large change as you would need a hose setup the supplies pressure and return to the pump from the brake booster and steering gearbox. You will also need to get a hydra boost brake booster unit and adapt it to your vehicle. A cheaper and easier to implement solution would be to add a vacuum reservoir with a check valve between the intake and current booster, or add a AIR pump that has the vacuum valving.
there is not direct connection between the power steering and the vacuum brakes unless you are driving a newer car that runs a hydraulic booster to the brakes from the power steering system. if you are having a braking issue, dont listen, take it into a shop and have it looked at. hydro boost as he mentioned is the other system. if you are running a cam with a high lift and duration, vacuum suffers so your booster would not work a well
Thats a hydra-boost brake system. Factory used them in some apps. Aftermarket sells kits to retro fit. It's not a simple change a couple parts type thing. You need a master cyl, master cyl adapter, hyd. hoses, fittings, etc. Pretty much remove all your booster, master cyl stuff and replace it with the hydra boost systerm Now depending on how large of a cam you have, you can try a vacuum reservoir. It's a $25 can pretty much that plumbs in line with your vac hose from booster to carb. The can fills up with vac and gives you 2-4 good hard press on brake pedal before it's empty When I rebuilt my combo and went with a 249/252@.050, 106 LSA, .570"/.579" lift cam, I lost most of my idle vac (3-4" HG at idle) where you need around 12" HG for power brakes to work good. I used one of the vacuum reservoirs and it worked but just not good enough for stopping a drag car doing 125 mph at end of 1/4 mile. I went with a strange brand manual brake system. No power booster. The pedal is harder to press, but the car stops better and in a shorter time with the man. brakes vs the power brakes and lack of needed vac
