    How to add an ebrake to a Dana 44 coverted to Disc Brakes

    I am trying to find out how I can add an emergency brake to a dana 44 that has been converted to a disc brake system. I am not sure what make/model the calipers have come off of. This is really holding me back on getting the TJ certified.

    I "DON'T" think all calipers have e-brakes.... ???

    Perhaps yours is one of them? I know that the caddy calipers do (Hence the relatively high demand on them).
    RIP OD, YOU'LL BE MISSED.... BUT that's OK 'cuz you've been REPLACED !!!

    ^ That would need all new brake parts....everything would have to be changed.

    If that is the GM caliper 7" bolt center size I think they are, you can use these:

    If it is the smaller GM 5.5" caliper bolt center, use these:

    ^ That's what I was thinking too, but it's an annoying design. Wonder if there's a way to convert the caliper to use a cam style cable actuated master cylinder.

    Is their anything in particular that I could look for on the caliper to identify the make?

    ^ Measure the caliper bolt center and read post #4. That should answer all of your questions. Judging by the pic, it *looks* like a large GM. A tape measure will end the speculation. They are a 76-78 Eldorado caliper.

    thanks guys.. measured the bolt centers and they look to be 7". I ordered the new calipers and they should be here in a couple weeks. What do I use for the ebrake cable?

    Did you order the TSM calipers with the integeral cable brackets (#3120) or the 76-78 Eldorado calipers from another source?

    TSM #3120 (Eldorado caliper with integeral bracket) = should be able to use OE TJ cables.

    76-78 Eldorado parts store caliper = *should* be able to use OE TJ cables BUT you will have to provide a bracket/mount for the cable housing to slide into.

    I think the Lumina car has a small caliper ebrake you would have to buy the cable / hydraulic actuator though, you'd be cheaper just going back to drums or getting the 05 and up rd44 set up.

    gotta look at his cost and what brake performance he can afford + drums work better than the stock rd44, It's cost me almost $500 to get them to actually brake like disk brakes should. Think the Acura Legend also ca\me with a small caliper for ebrake.

    I ordered the TSM 3120. The jeep has 5.5 inch suspension lift and 1 inch body, i was concerned that the OE cables would be too short

    I have never heard of anyone having trouble with the OE e-brake cables being too short but perhaps a TJ expert can chime. I'd be willing to bet that you will be fine with the stock cables.

    Hi. From experiance, as a GM parts Guy. Those GM calipers and e brake set ups are CRAP, with a very short lifespan on cars, so they sure wont last long on a Heep. You need some special tools to make them retract, and they seize up just sitting in the driveway. The Cutlass/Lumina they they came on where recalled at least 4 or 5 times. Seems to me, they used a vented rotor as well, so the thickness would be way off (could be wrong on that, but the wheel bolt circle would be way wrong)
    As far as the 44 goes, a lot of Grand Cherokees, came with 44A rear ends if equipped with a factory trailer hitch ( I own one) and they have disc brakes, with shoes inside the rotor. It works. Also, Ford Explorer 8.8's have exactly the same set up, and the parts exchange from the 44 to the 8.8 ( I also have one of those in my YJ). Seems to me the cables are also the same, or very similar. I just hooked up Ford stuff to my YJ last week, and if you use the Ford stuff, you dont need the adjuster bolt and Rube Goldberg set up..just grind down the front cable end ball and use a short connector..total no brainer

    My calipers arrived today so I am going to try putting them on tonight and see how they work. I am still trying to find some ebrake cables for it if anyone knows of anybody parting their jeep out.

    ^ Not worth your time putting used parking brake cables on your heep. They are inexpensve enough to buy new....there is no way to tell the condition of a used cable....and they can seize and cause you grief.

    Thanks CTD Nut.. i don't know what i was thinking when i typed that. I have ordered cables as well, the part that I am looking for is the ebrake cable adjuster. The part that connects the cable coming from the hand lever to the two cables going to the rear.
