Looking For E450 Trans Brake

vanderchevy18 · Mar 22, 2014

Like the title says, I'm looking for a GOOD E450 trans brake tail housing. Anybody have one? I'm going to use it mainly just to make my 4x4 trans work in the 2wd race truck, but I'm eventually going to go ahead and turn it into a trans brake for staging.

Smorris has me taken care of. Now to figure out how to hook it up to operate the way I want it to. LOL

Back to trying to figure this out. The trans brake I got was too long to fit in the trans.

what was the specifics on the one that didnt fit?
Ive got access to 3 ambulances that are being parted out. They should have trans brakes on em.

I have a parking brake that is mounted on the tail shaft housing from a e series bus conversion. Like you said it mounts up to a 4r100 4x4 output shaft. Is that what you need?

Yeah. I'll post pics and measurements of what I need later.

Can you hook it up with an air cylinder to actuate the brake? Then dump the air when you launch?
Air cylinders are stupid strong and act really fast if set-up right.
Would only add the weight of the air tank to the truck. They don't take much air and you can refill in the pits if need be. Don't need on board compressor, the cylinders don't take much volume.

That isn't the problem. The issue is the trans brake goes too far into the transmission housing and hits. It's too long by about an inch. I need a 4r100 brake that is shorter.

Brake I have is sitting in the bed of the bus waiting to go to the scrap yard. I took the trans for my van because it has the 4x4 out put shaft.

It's 2.5" from the slip yolk to the sealing surface though isn't it. I think they're all the same. What I think I need is the trans adapter that goes between the trans and the brake.
