    Hmmm... cannot make up my mind on this one. Should I run with the parking brake setup on the Dana 18 transfer case or should I use the setup that my waggy axle has on it. What would the pros and cons be for each setup? How big of a problem is brake lining contamination with the xfer case set? I've done brakes before on other vehicles but never on the xfer case setup.

    the problem with using the rear drums as e-brake is that you really can't pull them tight enough with the hand operated handle. My t-case mounted brake has always been trouble free.

    But the xfer case brake is infamous for being a bit, ehr, underwhelming at best. Just rebuilt mine, and wasn't able to stall the engine with it set. :oops: Still, some is better than none.

    Thad I hate to say this but my emergency brake on my Dakota won't stall the 318 in it with and automatic and thats with the brakes recently rebuilt. I don't use that as a judge of how effective the parking brake would work. You jerk that handle out at 40 miles an hour:shock: in a panic and I'm sure that you're gonna crap when the Jeep changes lanes or worse when that single 8" binder locks up, I know I certainly did, as I tested mine that way at 45 mph several years back.

    LOL, never thought of it as an "emergency brake". :shock: R) Was that an actual emergency or were you testing it?

    And yes, I get that the brake is much more effective at keeping the Jeep from rolling under its own weight vs. engine power. But then, so is a large rock. :rofl: R) But respectfully, I still believe that the ECJ5 parking brakes are in the bottom 50%.....

    The original owner of my jeep used it as the Brakes.:D
    I just wanted to test it, and I also used to play with the emergency brake handle in sports cars to do power slides. Oh that was fun!!!:D I'm sure that using it as mentioned above is not good on the u-joints but it sure was fun to do it once and to know that it would stop my Jeep decently if needed in an emergency.

    I set the t-case parking brake and pulled the tow bar loose on a hill, I have warn FF's on the rear that were not locked, never entered my mind, till the jeep was out of site, that the brake wasn't doing much good.

    I use my Tcase brake on hills sometimes, it holds fine. I would think that, with the hubs locked in, the tcase brake would have a mechanical advantage of holding 4 wheels from turning as opposed to just two (in a hill climb situation). I have had both types of brakes on hills and prefer the tcase type. Now for a DD situation the tcase would lose out due to the extra force from the two other wheels, hence the jeep moves under power when the brake is applied. I hope I explained myself correctly here.:coffee: :coffee: :coffee: :hurrican:

    Theoretically speaking, the transfer case brake should have more leverage over the tires than the brakes at either end of the differential because they have the added torque multiplication of the differential gears.
    Though the practical application is a bit different simpley because the Dana 18 has a tendency to leak get’n gear oil into the parking brake drum.
    Personally, I’m gonna rebuild my t-case, again :rofl: , hopefully eliminating all the leaks and install a transfer case brake.

    I have the warn FF kit on mine too, and this is exactly why I'm going with parking brakes at the wheels.

    I would think that the total swept area of the shoes on both back brakes would make up for the difference in leverage the tc brake has over them. I aslo think that having the ebrake engage at the wheel is a good idea on a vehicle that tends to brake ujoints and twist drive shafts as jeeps sometimes do. that said, I have a TC parking brake and it seems to work ok but I wouldn't put much faith in it during an emergency:coffee: $.02

    I didn't put my TC ebrake cable and handle back on as I have an mico brake but, someday I want to put a foot pedal actuator on it. I just need to get to a wrecking yard and find one that will work.

    You don't have an mechanically activated e-brake?

    I don't either right now but not because I don't have plans for one.

    There's plenty of discussion here and in the tech section on Micolocks and why they're not e-brakes or parking brakes...

    The only problem I had, and maybe it was an adjustment problem aslo, was that my xfer case leaked quite abit and the parking brake didn't hold well due to the gear lube in the drum.

    Still was effective when playing in the snow.......made cornering a blast:rofl: :twisted:

    I haven't heard anyone mention a big disadvantage to the TC brake: If you've got an open differential and get one wheel in some mud, away you go, the other side doesn't have anything to stop it. Ever ride a lawnmower down wet grass with one wheel going forward and one backward? I like my TC brake, never had any problems with it.
