Iv'e got this ugly brake booster mounted high on the firewall. What are the options in moving it. I can fabricate, just dont know what the "rules" are. Can I put it under the floor?
Got any pics of cool stuff you have done with ugly brake boosters?
and since I am talking about brakes, I have disc front and drum rear but no proporsioning (or whatever you call it) valve. Whats the story on that?
Thanks -M
What kind of car we talking about???? Should be able to hide it under the dash if there's room, or under the floor.
You should be running a residual pressure valve for the rear, and also a proportioning valve so you can set your front to rear brake bias. I use Wilwood valves, kind of spendy, but they work great.
Its a 46 Chevy truck. It is located high on the drivers side and the pedal hangs from way up under the dash. The space under the dash is mostly empty but I will have to take another look at it when I get to the shop today.
Is it possible to put the whole thing, booster and master, under there? or maybe just the booster and let the master look like it is mounted on the firewall.
I have also noticed when I depress the pedal, I hear a hissing sound from the booster, this doesnt seem normal. It does work though. One guy told me this is normal, but I just cant believe that, its loud and anoying.
Under the floor is good, but I will have to wait for the day the cab comes off for that one.
The booster is ugly, someone needs to develop a nice looking cover for the lazy people, like me.
I am going to investigate the valves from Wildwood.
Thanks for you help.............again! -M
I've been using an 8" dual diaghram booster with a Corvette master cylinder, nice sized booster and on the master cylinder you can have the lines coming out either side.... Should be a picture of it on one of the Mercs in my gallery......
They do sell nice shiny chrome ones if ya want to spend the extra $$
Part of the reason for building a car is self expression, and as such that brings a touch of art to the equation. The origins of hot rodding are based on performance, and the biggest contributor is the engine. For years rodders left off part or all of a hood assembly to show off thier "bullet". That's my long winded rationale for why I really dislike firewall mounted master cylinders, and power boosters even moreso. They are a major wort on what should (and can) be a pretty face. Some will whine "Its about go, not show!", but if you're building the car one doesn't preclude the other (a point that some narrow minded folks don't get when they think a well turned out car is a trailer queen when in reality it's driven).
If you like a swing pedal, and/or have limited under floor space on the frame, take a look at some full size Dodge vans. They have an under dash booster/m.c. unit, similar in design to the after market one made by Kugel http://www.kugelkomponents.com/produ...akesystem.html They're a little bit of a pain for checking the fluid level, but in a good system that's not a frequent requirement.
Under floor systems are made by many suppliers, and as Dave said, you want a proportioning valve, as well as residual check valves. Here's a nine page article that will probably tell you more than you want to know; http://www.hotrodheaven.com/tech/brakes/
