    Well my stands finally came in and I found time to install one side yesterday and take some pics.
    They do need a couple mods to fit right but work quite well with a couple adjustments
    When I was working out the details with Litneon he mentioned how the brake pads overhang the outer edge of the rotor a little, we decided to move the caliper in a little to minimize this. Unfortunately this caused the caliper to move in enough to foul the original caliper mounts.
    Thankfully it is only a minimal amount and I was able to grind the edge of the bolt holes on the new caliper to get the clearance I needed.
    this did minimize the pad overhang and I used my cutoff wheel to trim of the excess on the pad, I also cutoff the low pad indicator since it just hangs inside.
    I also found the rotor does not perfectly center in the caliper, I think it could be used like it is as Litneon does with his now, I used a washer between the caliper and the stand to push the caliper back further and center it better over the rotor.
    I was also able to use the existing brake line with some tweaking, I cut the bracket in half and enlarged the original mounting hole that was left next to the hard line mount, I used the top caliper bolt to hold the bracket and bent the hard line to meet the caliper.
    A side note the original rotor is tight on the hub and you will have to drive a chisel between the back of the lug bolts and the rotor to force them apart and then between the rotor and hub.

    here are two slide shows of the pics I took

    finished! just have to bleed em!!

    By the way... you will need another set of bolts to mount the caliper
    the original caliper bolts work to mount the new caliper stand
    but you need bolts to mount the new caliper to the caliper stand
    the ones used with the 4wd caliper are much longer and have a larger threadless area... I luckily have a 4wd parts truck and stole the caliper bolts off it...
    they are the ones you need the 2wd caliper bolt won't work....

    Done!!!

    So I bled the brakes and took it for a spin today....
    UNBELIEVABLE!!!
    It brakes so good I can lock the front tires at anything over 30mph, without even stomping on em.

    I have 4 pairs of these left so If you want a pair let me know... $80 + shipping

    I will be putting them on eBay for $100 if they don't go to you guys soon...

    Absolutely the best mod you can do for your truck especially if you are running big wheels...and I know you are!!! LOL!

    First make sure you read through these two threads...

    http://toyotaminis.com/forum/showthread.php?t=241


    http://toyotaminis.com/forum/showthread.php?t=252


    the basic parts list is:

    2 wilwood 12.19x.81 rotors with a 7.62 bolt circle
    2 wilwood rotor hats 2" offset with the 7.62 bolt circle
    16 5/16-18 3/4" sockethead bolts grade8 and lockwashers (I will include these with the caliper stands)
    2 of the caliper stands I had made
    2 toyota 4wd brake calipers 86-95 (preferably loaded with pads or you will need pads)
    4 12mmx1.25 bolts for toyota 4wd calipers (you would need to get these from a junkyard or toyota parts dept.)


    The swap is pretty straight forward
    first remove the old parts
    disconnect the brake line from the caliper and remove the two bolts that hold the bracket for the brake line (easier to do when the caliper is still mounted)
    remember to catch the brake fluid with something
    unbolt the caliper and remove
    there are 5 bolts in the hub next to the wheel studs that bolt the original rotor to the hub that need to be removed.
    remove the bearing cap, cotter pin and spindle nut
    there is a washer behind the nut and roller bearings
    the hub and rotor will pull off the spindle now
    use a chisel between the back of the wheel studs in the hub to wedge the rotor off the hub
    reinstall the bare hub, roller bearing, washer, spindle nut, cotter pin and bearing cap.
    install the new caliper stand using the original calipers bolts
    install the new rotor over the bare hub
    the new caliper will need to be ground down next to the mounting holes for clearance, then mount the new caliper (this is easier without the pads installed) You need to use the bolts from a 4wd caliper that you got from a junkyard or toyota parts dept.
    install the pads
    Now you can either buy braided stainless steel brake lines and use them
    or "tweak" the original lines to work
    I used my original lines... I removed the hardline mount bracket from the line, then I cut it in half so only one bolt hole and the line hole were left, I then used a hole enlarger to make the bolt hole that was left big enough for a caliper bolt, I then used a hammer to flatten the bracket, I stuck the bolt hole end in a vise and bent the bracket with a hammer at about 35 degrees.
    You will need to bend the hard line up and turn the end of it 90 degrees to meet the caliper. use the top caliper bolt to mount the modified bracket
    You can see the modified bracket in my pics....

    Let me know if you have any questions....

    Interesting swap, but if you are going to go through the hassle of building stands why not dump the stock calipers?

    Hey Shoes...

    you can paypal or mail me a money order $80 plus shipping = $88 UPS with tracking number
    let me know which and I will PM you my info

    the links to the hats and rotors are on the other threads about this and the links to those two posts are on the first page of this thread in my previous reply to you

    the link you sent for the rotors are the correct ones... but...
    the best deal on hats is at jegs
    http://www.jegs.com/webapp/wcs/stores/servlet/itemproduct_10001_10003_191548_-1_763618_30155
    and the best rotors are here at carshopinc
    http://wilwood.carshopinc.com/product_info.php/products_id/57622/160-5844
    but if you call jegs they will pricematch the carshopinc price and they ship for free.. so you can get the best deal on both from jegs

    yes the hardware I send with the stands are for bolting the rotors and hats together...

    you really need to read thru all three threads on this....

    oh and you noticed my double steering stabilizer...
    I went with two stabilizers since when I went to 8 inch wide front rims my truck started really getting pulled around in the bumps and ruts on the highway
    it did help a lot but my steering is stiff

    Received the adapters today. Thanks for all your work. Won't have a chance to mount them until some time. i was just wondering if having them made in aluminum would be any different. I am also curious what process did they use to make them.
