Help, Need Parking Brake Assembly

Lost power to rear wheels in northern New Mexico. Was towed to Raton, NM and now setting in RV park. Drive shaft was loose going in to back of parking brake unit. After removing brake unit found that the front bearing had disintegrated and the input shaft broke even with the end of the transmission tail shaft. Still waiting to see if the mechanic can get the brake parts off of the shaft, if not new transmission along with brake unit.
NOW the problem cannot fine a new or rebuilt brake assembly. Ford is searching but no word yet.
2014 F53 24K chassis. Part number on unit is 6C24-2598-ABX
By the way the unit never showed any sign of leaking.
And checking fluid level is not on the maintenance schedule.

wackymac, Thanks, you have 4R100 transmission mine is a 5R110W. I did give them a call, no luck. They showed a dealer in Ohio having one and gave me the phone number again no luck.
For now there is a shop in Illinois that has a used one they will pull Monday and ship second day.

I had a similar failure. The parking brake didn't come off without a fight, and when it did, it brought the output shaft of the trans with it. Shaft was seized to the parking brake. Never came apart.

I'd get things apart before you do anything.

In my case, I had to have the trans rebuilt, and replace the parking brake. I was lucky to just have to rebuild the trans, not replace it. And I was really lucky to find a cheap ($75) used parking brake that I didn't have to do anything to.

WOW, this parking brake seems to be an issue, maybe or maybe not, but so far at least a few people having problems with them.

Is there something that can be done to prevent such damage?

Seems like with all the dealers out of stock etc... there is a problem with this design.

Now granted there are thousands of these being used everyday, so might not really be that big of an issue.

tderonne was able to get the brake off. The brake unit shaft broke off even the end of the transmission tail shaft, see picture. Have been able to move the part on the tail shaft about 1/4" so far will get a bigger puller tomorrow.

CJ7365, the good news is Ford stopped using this parking brake assembly when the 6 spd came out 2016 model year.
The problem is checking the oil in this unit is not in the schedule maintenance list.
Deep in the owner's manual "Check the parking brake fluid level only if
there is visible signs of fluid leakage"
From now on I will check the parking brake oil level at least at ever oil change.
I never saw any oil leak and I have parked on a concert floor for the last three years.

I'm on my third one now. Always seem to leak. It's a pain to check or add fluid. They only hold about 4.5 oz. of ATF for lube. Keep an eye out for drips on the bottom of the "backing plate" next to the brake drum. I'm going to rebuild one this winter at my friend's machine shop in Santa Cruz.

We probably need a sticky for the e-brake fluid check.
