Just wondering if anyone has used one, How noisy are they, where did you mount it?
we installed both the ones from summit, the lower operating vacuum one first and then the higher one. They are fairly noisy but it you rubber mount it and have any kind of motor/exhaust it covers it off, that said you'll never get used to the random vibration of it cycling.
Was it worth it? if a big cam and soft brakes then yes, if its just to hold you over until a brake swap just get used to the heavy pedal and remove/break the valve in the booster.
You are really chasing your tail on this issue. Just install manual discs and be done with it.
Not the best advice. The pedal geometry between a power brake car and a manual brake car are different. Very different. Doing this compromises your safety and the safety of others around you.
just a hard pedal... caused by bore size and leverage, if you can push the pedal the car will stop. If you have a bad leg or a weak leg then yea, probably not the best idea but if your healthy and without issue you can push it. At the end of the stroke the same pressure at the wheels is being applied.
I can lock up all 4 on the swinger with factory disc/drum and un-powered power brakes (wouldn't be that way if they will made a check valve with a 3/4" nipple for the 13/16 seal...)
Um, no. Pedal ratio is different between manual and power brakes and master bore sizes are usually different also. I now refer you to Pascal's Law on fluid dynamics.
I agreed that you can stop a power brake car with out power. It is not a safe thing to do or recommend to someone that they disable their booster and drive their car.
As others have said, convert to a manual brake master cylinder, then go drive the wheels off of it. I did and even my wife can drive the car with no problems.
Or,
Take the kid's advice and join the manly thigh club.
I think some people are using the used pump from a saab or volvo with success. One version or the other has a built in vacuum pressure regulator so, self regulating.
