    Remove the 8 bolts on the hub that is holding the axle in place. Then................damn, it's been a while, but I think the next step is to move the rectangle piece out of the lock nut. Then use a hub socket (6 prongs) to remove the lock nut. This can be done with a hammer and screw driver too, but will be painful (I used that method the first time), then I think that's it. pull the hub/backing plate out. Man, it's been so long, memory is a little fuzzy [​IMG].

    I just disassembled mine a few days ago, and it sounds a little different so I assume there are two different types.
    1. Remove the 8 retaining bolts on the hub
    2. Slide out the axle shaft
    3. I didn't have a key on mine, but instead had a locking washer behind the first nut, pry these back before unscrewing. I also used a flathead screwdriver and a rubber mallet to work it loose ( 1 light hit) and then spun it off by hand. You can purchase the correct socket at your local parts store (looks like a piece of pipe with a keyed end and a 1/2 drive on the other.
    4. slide off the retaining lock washer (wont spin off)
    5. spin out the final nut from behind the washer
    6. slide off the drum
    7. Unbolt 4 bolts on the backing plate and your done.

    Good luck

    I thought the calipers had to be '76 or '77, but I am not sure it's been a while since I converted mine. I used '76 on mine.

    No, it should all come off real easy, unless your drums are worn and have a lip grooved into them. If thats the case, you might need to adjust them loose from the hole in the backing plate before it will come off. the hardest part in all this is getting the lugs out of the drum to remove the brearing carrier. I'm planning on getting new lugs so I just pounded mine out but if you want to reuse them, a press and a copper block would be a good idea.

    No. The rotor simply replaces the drum.

    If it breaks, it wasn't good enough!

    I'm not sure the front d44 hub and bearings will fit. It was my understanding that you would have to press the lugs off the 14b hub and drum, then reuse the hub and run new lugs throught the 3/4 ton d44 rotor. There may be a way to do what your suggesting but I'm not aware of it.

    Anyone have any ideas?

    J.C. if you have any more questions about the install you can also contact me via pm or email and I can help you out. You will have to press the studs out of your 14 bolt hub/drum and seperate the two then place your new rotor where the drum was and press the studs back in. You do not use the d44 hub.

    Derbinator, have you or anyone else figured out any neat tricks for making the caddy calipers E-brake mount on top of the axle yet still blead without unmounting them? I don't have the calipers yet but wonder if mounting the whole caliper above the axle as opposed to behind it might put the bleeder in a better position. Then run the E-brake cable to the axle where you pivot a linkage to properly engage the caliper E-brake lever (since the e-brake lever now needs to be moved down instead of forward)? I'm sure if I had a pair I could see if it would work or not but I'm not that far along yet.

    JC,
    Yes you could have napa do it or if you have an old lugnut put it on to were the studs are not quite coming thru and tap (beat) them out with a hammer. When you put them back in just use a hammer and punch or similar item to tap them in. If the bearings are still in the hub make sure to cover them with a rag or something to keep them clean as tapping (hammering) tends to knock alot of dirt free.

    BorregoK5, I'm not familiar with the caddy e-brake but as far mounting the caliper on top instead of slightly behind it would just be a matter of rotating the holes in the bracket so it can be mounted in that position. As far as linkage for the the cable I would think that wouldn't be to complicated either.
