replacing brake chamber - issue

I'm a little confused, but...
I just try to cut the new one beside the old one uncaged and try to get the same leanth. That's what I have done.

 

I'm guessing running a die on there to get more threads isn't an option?

 

You probably have the wrong Brake Chamber that won't work for your Application.

It's best to call the Dealer, give them your VIN and get the right Part Numbered and Make of Brake Chamber for your truck.

I know most people think any Brand Brake Chamber will work, but there are differences in thread length, rod length, etc.

Same thing happened to me, a Shop sold me a Brake Chamber, I uncaged it and cut it, installed it and it was fine. I found out later after driving it for awhile the Slack Adjuster was hitting the Differential Housing.

It was found out that the Rod was too long still, and the Clevis needed more threads on there, which the Rod had none left.

The Shop sold me the wrong 30/30 Brake Chamber.

I had to call Dealer and they gave me the Direct Replacement Part Number for the Brake Chamber that will work correctly for my truck.

Luckily I was able to get my money back on the other one on the pretense that they sold me one that they stated would work and it didn't.

 

The part with rod rarely needs to be replaced.....I'd just replace the front part...much easier....

 

Ok I get it now.. When the parking brake is applied, it will go in up to the threads. I don't think you need to thread it more, also the slack adjusters will take up the correct leanth once you adjust them with the parking brakes off.

 

I've done the die thing once or twice. In all honesty, its so much quicker to change out just the park brake chamber half and leave the service pot if its good. Usually about 15-20 minutes to do that.
