Me Again, I haven't heard of this problem with 'older trucks'. I sent cummins12v98 a pm. I love my old 7.3, I have done a ton of work to it and that's one of the reasons I keep it, I CAN WORK ON IT!!! I keep saying I'll buy a new pickup one of these years because as time goes on my body is breaking down, LOL. New pickups I can't work on for obvious reasons. OK, enough off topic, if this is my problem then I would like to correct it before my wife and I get killed. Why wouldn't the tech guys talk to me about this possibility instead of just sending me new ones?
Edit: My pickup with the new brakes can stop that 5er, no problem. I was towing my Travel Supreme and lost its brakes all together. I didn't have far to go so I went for it and my pickup stopped that 5er fine. Found out the fuse next to the Carlisle disk brake controller blew the fuse. The Carlisle people (now Cargo Brake) told me in cold weather to up the number on the fuse, I did and never had a problem again, except the one we are discussing. Thanks you guys for this help!
