I found a great deal on a 4" d-celerator unit from US Gear. Only problem is it is just the brake, no wiring.... It is AIR actuated.

I'm looking for help with the set up. I don't know what all I need. I'd like to get the break set up before too long. I know I can buy the wiring harness from US gear for about 300. Just wondering if it'd be worth it or if I should design my own... using your help... of course!

Pictures would be great..... I AM VERY VERY NEW at this and want to do it right....

 

I think you could build a setup way cheaper than $300. Get 2 air solenoids from grainger (1 to fill and 1 to release air) and put them on a 3 way switch (up to pressureize the actuator, center to hold the air in the actuator, and down to release the air from the actuator. pretty simple and should be less than $100. get some quick connectors and plastic tubing and you should be in business. I just hooked up a friend's air bags with a similar setup, works great.

 

To do it right you'll need a compressor, tank, air lines, pressure switch for the tank, solenoid switch for air feed to the brake and a contact switch for the throttle. You would also probably want manual switches on the dash somewhere to enable/disable the brake and/or compressor manually, if desired.

I didn't see anything in your sig about onboard air already installed.

 

nope, no onboard air.....

 

My fault, I was under the impression you had onbaord air when you said you can get a wiring harness for 300 bucks. Now we all know what assumptions do... I still think you can do the whole setup minus the brake itself for around $400. You would need a tank, compressor, pressure gauge, solenoids, switches, and air tubing. You will need to do a TC lockup switch which takes about 30 mins and $4 in a switch and wires. to properly utilize the exhaust brake.

 

Under the circumstances, I think I would try to do it in phases. Get an air system installed and working, then get the tranny ready, and lastly go for the brake.

Good three-day multi-stage project.

 

I have the same brake, air actuated, and it already has a solenoid attached to the actuator. The solenoid is a 3 way so not activated it releases air from the piston, which is spring loaded to open the brake valve. So you only need to apply air the actuator to engage the brake. But i added one more valve to the system that only opens when the ignition switch is on because the valve on the brake leaks a little so this helps hold air in the system longer.

So to actuate the brake all I have is a toggle switch on my shifter. I did have a throttle switch, but after it didn't engage a couple times I took it off.

Also I wanted on-board air anyways, so I got a valair 100% duty cycle compressor, and mounted a couple air tanks that I stole from a truck sitting behind the barn.

any pictures of the set up (brake and air)?

Thanks.... That's the direction I'd like to go....

 

Sorry, no pictures, if it stops raining, i'll try to get some this week.

 

A little late, but as promised here are some pictures of my setup.

 

Air supply looks a little small, Aaron - I think you need another tank...

 

Hey thats all I could fit under the truck. The truck I stole those off of has another tank, maybe I could bolt it on the outside of the frame somewhere? If you really think I need another? funny guy.

But seriously I want a train horn. and I can run an impact if I ever have a flat.
