transfer case parking brake

[cmyoung2]

There will be too much movement between the transfer case and frame/crossmember.

Are you using a mechanical spot caliper?

Yes. Mechanical spot caliper.

The Ford 04' E450 box truck that I used to own had an emergency brake on the drive shaft just behind the transmission. Too bad I sold it or I could take some pics. No idea on what other applications Ford may have used a drive line brake. You might find something in a bone yard to learn or scavenge from?

You do have me wondering though. I have a Ford E350 passenger van out in the driveway now. Guess I need to crawl under it and see how that one is made?

Old medium duty trucks had the parking brake at the back of the transmission too. The thing is, unless you have posi....real posi (spool), once one wheel breaks free, there is nothing holding your vehicle. There is a reason they don't do some things any more.

my f450 has a driveline mounted parking brake. it works very well

My old '81 Ford LN600 dump truck had the drum brake behind the trans and it would hold a 10 ton load of gravel in the bed on a hill. The shoes were ridiculously expensive though.

Only problem I've seen with the driveline brake is when you break an axle in the truck. Happened to a friend's rollback, broke an axle trying to take off up a hill loaded.
Had to wait for someone to come with wheel chocks before he could get out of the truck.

Other the the pain of maintenance I kinda like the system I've seen on some older trucks that uses a separate actuator on the brake backing plate for parking. Forgot the name of the system buy older ford F600-700 etc. seemed to use them alot.

OP I'll look for the driveline brake off of a 350/450. We have plenty of old ambulances around, maybe I can get one that way. Looking for the mounting plate, not interested in the drum brake. I understand about issues of the driveline brake, but any brake is better than none, and like I said, the current parking brake is 4wheel low in first gear.
Thanks for the interesting replies.

I don't think I've ever seen a 350 with a driveline brake and rarely see 450's with them. Even my 2000 F550 used wheel mounted parking brakes.

I just looked at the new F450/550 ambulances we have at work and they have what looks like a hyd. wheel mounted parking brake.

I will admit the Ford parking brakes on the 99 and up trucks can be temprimental but work well if setup right and used regularly.

I use to park my F550 with a loaded 3 car trailer and the brake held fine.

As I stated, my 04 Ford E450 box truck did indeed have one. The truck was manufactured as a cab/chassey then upfited with a 16 foot box. I only put about a dozen k miles on it in the six years that I had it. The rotors and disks on the four wheel disk brake system were looking pretty rough but I never had reason to work on the e-brake which held fine even though the open reared truck would get stuck on "snot".

Way back when, I did drive a number of vehicles with driveline brakes that may have indeed suffered from a lack of maintenance and they were pretty much not to be trusted.

I didn't mean to imply yours didn't, just wanted to let the OP know it wasn't standard equipment on all the trucks.

They were an option on the F450 and F550 although I rarely saw them on the trucks that came through the shop. I never saw the option for the F350 CC.
