Air to Hydraulic Brakes

[Rebelpride]

Was sitting on the porcelain thinking chair today and wondered if you could take the deuce brake system and make it all hydraulic, that way there would be no brake failure from lack of air. What purpose does the air serve?

 

[jwaller]

the air is a booster just like a vacuum booster on a car. if you had arnold swartzeneggers leg then you might could do that.

 

[clinto]

As jwaller said, the air is just a boost. You'd be well served to spend your time trying to come up with a reasonably priced dual circuit brake upgrade.............

That would be far more useful and if it were cheap enough, you might even make a little spare cash selling the kit to fellow enthusiasts.

Ok, I'm new to working on big trucks, so do beat me up for being stupid here!

Why couldn't you take the vaccume assist hyd. brake booster/master cylinder/pedal assembly off of say a 1 ton truck, and put it on a deuce? It would eliminate the air system, make your brakes completely hydraulic, and all you would have to hook up is a vaccume line.

diesels don't make much vacuum. Why get rid of the airpack? When properly maintained, they aren't much trouble at all.

 

[russ81]

Thanks for the info. Like I said, I'm new to this stuff, and have never delt with this type of brake system before.

Spicergear modified his deuce with a hydroboost(hydraulic, uses power steering pump) system off a newer large truck. Said it works well.

 

[russ81]

I'm just looking for the simplest, easiest to maintain system. The fewer moving parts, and the fewer accessories the better for me.

Air Brakes...

Brakes from a one ton truck?

Uh, because that truck is alot heaviertham a one ton truck.

Do have to release a parking brake valve to set the parking brake?

RE: Air Brakes...

The deuce system is a very good system and requires little maintenance. I think you'd be hard pressed to find a system that performs this well for as little money and maintenance.

The little maintenance that it requires is important, though.

I've bobbed my deuce so it's not a lot heavier.

RE: Re: Air Brakes...

ah..sorry not familiar with term bobbed.

I know you'll come up with soemthing,

Good luck,

Tom

It's just like the vaccum sysetm, but uses pressure instead of vaccum.

Bobbed as in shortened.

Bobcat, bobtailed, bobbed hair.

A LDT-465 doesn't make any vacuum at all. It will have positive manifold pressure because of the trubo.

Disconnect the hose from the air cleaner, stick your hand over it, let me know what happens. There WILL be vacuum on the intake side of the turbo.

From the info I have, a bobbed deuce is still close to 11,000 lb....empty...

 

[JasonS]

My bobbed deuce with the ~900lb gas engine weighs right at 8klbs. About the same as a full size pickup.

Yes there is if you cause a restriction with your hand. If you have very much vacuum at all with everything in place you better clean your air filter.
