Emergence Brake

Scott Thanks for the grate pics I'm going to attempt to do this it looks a little intimidating but II have searched the internet on this and some say it's really not that bad. So thank for everything.

Scott & Jill,
Well Sir, as has been stated, it's not an easy job. To remove the unit from the coach is not all that bad. Once it's off, to start with, there is a large, I think, 2 5/16" nut on the end of the main shaft. If you've got a 1/2" drive impact gun that's rated fairly high in torque, that will do the job. You'll need it for re-assembly too. But, it's a very, very tricky and unique assembly as it almost has to be put together "outside-in". Sounds odd doesn't it?
The way the tapered bearings are situated, it's just a semi-backwards way of assembling it. If I can find all my pics of when I did mine on our previous coach, a '99 Fleetwood Bounder 34V with the V-10, I'll post them so you'll see EXACTLY what you're up against.

The real funny part of acquiring the gasket is, you're actually purchasing a gasket for a transfer case-to-transmission. Most of the Ford parts guys are clueless in this application. You see, that transmission can, and has been, coupled to a transfer case for 4WD applications. They simply remove the tail cone and, mate the T/C up to it, using the said gasket.

But, if you go into a Ford parts place and ask for a gasket for your parking brake to transmission, more than likely you'll get the deer in the headlights look or, the crooked puppy head look. I haven't seen any talk about the ZF parking brake in quite some time.

P.S. When you look at the close-up of my brake shoes, you'll see some serious cracking and pitting. That's from leaving the parking brake on while driving, not a good plan. Needless to say, those brakes endured some serious heat. Back when I rebuilt mine, Ford said they AREN'T REBUILDABLE!!! I told Ford, WATCH ME! I got it apart, got new shoes and, kept the bearings as they were flawless and, re-assembled it. Yeah sure they're not rebuildable. For what Ford wanted for a complete unit, at the time, $1,600.00, I was DEFINITELY going to give it my best shot before forking out that much coin.

Richard Thank you for the link to the Emergence Brake this will help a lot.

If you research there are instructions on how to rebuild them you need to replace some seals and a plastic sleeve that breaks when you take it apart and a gasket and new brake shoes. C.H.Topping a brake shop in Long Beach, Ca. can rebuild it for you.

Thank you for your reply
Do you have the instructions and if not what would I look under to get it ?
