    I just installed mine last night and tested it it with a dpdt switch it was pretty exciting to see the caliper work. For final wiring I am going to use resettable breakers to limit the amperage and am also going to get a momentary dpdt switch which I figure will allow me to just hold for for in and out. I used an axle from a 73 with one piece shafts and the set up went together great but Brennan gives you everything you need to use an earlier axle.

    If I hadn't rebuilt the entire axle I bet you could do the install in less then an afternoon. I should have the Jeep back on all 4 wheels next week and will start plumbing and final wiring and will give an update. [​IMG]
    Best part is the price this is what I paid for my parts I think it would be hard to rebuild the d18 ebrake and drum brakes for this price. Only issue I can see is it not being fast enough for ebrake turns but we will see.

    What do you have for front brakes, Brennan's "Track Kick" kit? I've just added his kit to my dana 30, but haven't hooked it up yet. I'm curious if the fusion calipers would alter the braking bias vs the normal kit or drums. Please share when you get it on the road!

    I'm doing his brakes on the front too. I should be able to button that up this weekend I am rebuilding the axle then next week will be plumbing and bleeding. I will let you know how it goes.

    Here is what I got
    Brackets Trackick Disc Brake Conversion Bracket, One Pair
    Calipers I ordered off ebay $50 a piece
    Passenger Right Caliper Rear Fits 13-19 FUSION 2060730
    EDGE 2019 Caliper 2035946
    MOTORCRAFT WPT1506 Parking Brake Switch Connector

    Switch and brakers are untested at this point but I ordered
    https://www.amazon.com/gp/product/B082QXGPZ4/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1
    https://www.amazon.com/gp/product/B08JTS3DVR/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
    https://www.amazon.com/gp/product/B08JSQ3YVV/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

    I would not order the witch again as it is not a momentary switch which I think would be helpful in this.

    Everything has gone together smoothly I will sketch up a wire diagram once I verify that it works. Only issue I am running into is my parts store sucks so I have to wait for Amazon to get me some banjo bolts for the rear brakes.

    316 is the number on the correct caliper brackets.

    I went with a simple setup. They both work independently of one another. :sneak:

    $40 calipers
    $120 Caliper brackets
    $20 organic brake pads
    $15 brake hose for a '13 ford fusion *I bought this hose to fix an issue I had so it's not needed if you have tracker disc brakes. Anything with a 10mm banjo fitting should fit. If you already have tracker brakes then you could reuse them, I did (driver side). If you use a 95 S10 2wd front brake hose it is a 10mm banjo and 3/8 on the other end so you don't need brake adapters.
    $15 DPDT momentary switches
    Tracker/samurai rotors * I had to drill the stud holes out with a 5/8 drill bit to sit flush on my wms.*
    Wiring is simple. I used a few different colors because that's what I had on hand. Don't leave the wire too tight or it could pull apart while the suspension does its thing. The wires will get covered in wire loom and tucked away. When you compress the caliper piston DO NOT force it in with a c clamp. It screws in clockwise. I used a pair of needle-nose pliers but they make a tool to do this.

    So they screw in like VW/Audi rear calipers. I used a set of needle nose pliers too! This is a great setup.

    Maybe I missed it, but is there a manual release on the calipers as backup in case the electrical is damaged somehow? Thinking more along the lines of the parking brake being engaged and not being able disengage them electrically for some reason.

    Maybe by taking the caliper off and screw the piston back in. I mentioned elsewhere that motor failure is my only worry with this.

    If this caliper would crush the pad into the disk hard enough to lock up a wheel, i don't think you could get it off that way. How to get it off is a good question though.

    I really think I want to do this conversion. My d18 parking brake is not up to the task even when everything is new and adjusted right with 35" tires.

    Looking at the calipers that they sell with no motor at Rockauto, it looks like maybe you could take the motor off and spin the shaft manually somehow to disengage the ebrake.

    I’m liking it on paper for sure. I think getting the geo setup in front, this in the rear, and stock master is how I’m gonna setup the brakes on “Dad’s” Jeep (the 48).

    I just wired mine up and used resettable breakers it doesn’t pull enough amps to trip them so I think if I were to do it again I would just use a fuse and momentary switch

    So about the clamping force....a fhead, t98, 4.88 equipped jeep can drive through one parking brake applied while in reverse high range. In fact, I'd imagine it could drive through both applied without too much fuss. :whistle: I tried to move it by hand and it didn't budge and that is what I care about most.

    Maybe when the pads wear in it'll hold better.

    My '56 cj5 e-brake certainly needs re-done. While looking at this thread, it occurred to me that it might be possible to replace the original drum e-brake set-up with some kind of simple rotor disc e-brake? Maybe with a shield to deflect any oil leakage? I'm not a real mechanic by any means, so the simpler the better, but I couldn't help thinking about it. Any and all responses welcome. (even an emphatic "No way" ! ... Ha Ha)

    I just replaced the shoes on my 71 parking brake. I looked at some of the trheads on this topic and became worried about my fab skills and my ability to procrastinate, I just went with replacing the stock shoes.
    Try using Google and start your search with "earlycj5.com" then add your search terms like 'transfer case disc parking brake'. You should see several threads.
