It's my tcase, but I haven't bought one. I just loaned my tcase to them to do the build up. I might buy one, but right now I have some other issues to take care of on the car.
For those of you with a tcase disc ebrake...

From the looks of it, as long as you can get something like a pulley to have the cable pull from the side, you can maybe weld a longer piece of metal to the caliper lever on the TSM kit. Obviously you wouldn't want to make it too long, since the handle itself can only travel so far. Maybe use one long piece, drilled in one inch increments, then just experiment to find the ideal length............and sell the idea to TSM
My real concern is that I don't want to rebuild my tcase just yet, so if I have to actually pull the entire output shaft to get at the backside of that flange to put the rotor on, I'd wait until I get a 60 Tcase (for the full manual shifting) and install the brake while rebuilding the case.
Good idea Spook.
The rear flange on the 60 splitcase is removeable so no case disassembly is necessary. Just take the stake nut off and tap off the flange. It might leak some oil though since the flange seals the opening (if I'm remembering right) so draining it first is probably a good idea.

So Mike .. when you where ready to make more magic and create the t-case e-brake that worth !

Just poked in here out of curiosity and I'm surprised to see so much interest.
I would like to make the point that unless you REALLY need to run a t-case ebrake, it is fundamentally a bad idea.
We are talking about an E-brake, E as in EMERGENCY, and having it rely on that many components of the drive line is just a bad idea, especially something as prone to damage as the drive shaft.
Thats, it. I am gone now, back to the thread.

I think that a lot of people want them so that they can put on rear disc brakes. I think the additional safety gained from full time 4wheel discs would outweigh the concerns about the potential use of the emergency brake in an emergency, but I'm probably not considering all angles.
For me, I never use the emergency brake other than to hold the car still while parked on a hill.

Same here. I use it as more of a parking brake, but if the situation should arise that I need an ebrake, I want something that will stop the truck.
I figure if I'm in a situation where I break my rear driveshaft (how often has that even happened?) AND my brakes go out, I'd be in 4WD anyway, so I'd still have the ability to use the braking force through the front driveline.
I sheared my 40s t-case e-brake off when I was test driving it. Didn't know it was on and the truck was in low range. Popped it off like the bolts were nothing.

Every time I see this topic come up I am always surprised some company hasn't come up with a caliper design that works with the handbrake.
I have the JTOutfitter disc setup using Eldorado calipers and for regular braking, they work great.
When I need to use my parking brake though, I would give it an F. You really have to pull up on the hand brake as hard as you can then pump the brake pedal too since the Eldorado calipers are GM and the GM cars used foot e-brakes.
If I do that, I can barely get it to hold in neutral on a 2% hill (aka my driveway). Even with that, if I pushed on the front end, I could still push the truck down the driveway.
I don't like the idea of the transfer case e-brake all that much either, but really, it seems to be the best option.
Does anyone know any mechanical engineers that work in the auto industry? We need a ground swell movement on this...

Note two things on late models, they call them "parking brakes" and they are nearly all drum style brakes internal to the rear rotor's hat. Neither is an accident.
I've bt-dt when I worked in R&D for one of the aftermarket racing brake companies. Designing a mechanical caliper looks easy, but the devil is in the details. Cable/linkage travel vs clamping force is a much more delicate balance than might be obvious.
Disc brakes as parking brakes aren't that great of an idea. A drum is self-energizing and it's large surface area means that it is better suited to holding position than a disc. Shedding heat is a disc's advantage, and there isn't much of that in this application (p-brake). When used as an E-brake it's better than nothing, but seriously if you need that yer skrewed...
E-Brakes really came about because of early hydraulic brake failures. We've learned a little about making high pressure flex hoses & plumbing since the 1920's, but the law hasn't been changed.

i have had customers cars come in with a bad master cylinder that failed on both halves of the cylinder (rare but does happen) and had to pull em into the shop and stop em with only the emerengcy brake.

No denying their usefulness that way, but I get the impression that the OE's no longer call them "Emergency Brakes" for legal reasons.
