    White Womper and I just finished installing TSM rear disk brakes on the UAV, real straight forward install except the kit does not come with any kind of bracket to use with the factory e-cable. Looks like I could just fab up some kind of l-bracket and make it work, what have you guys done?

    just getting ready to do the same conversion... got everything from TSM also (ss brake lines, calipers, and portioning valve) except I've got misfits backing plates! [​IMG]

    would like to see a pic of what you end up fabing...

    Also ORU has a master cylinder I've been considering throwing on to go along with this thing. take a look at it and let me know what you think would you???

    That's a hydro boost system, I believe it runs off your power steering pump or something which I wouldn't want. If you want to upgrade get one out of a 3/4 ton truck.

    I wanted as much clearance as I could get onmy e-brake cables so I mounted my caddy calipers reversed. The left caliper is on the right and the right is on the left. This makes it a pain to bleed the brakes but that is mostly a one shot deal. With the calipers mounted this way I fabbed two cable brackets that mount to the 1/2" bolts holding the caliper plates in place. The e-brake lever points forward above the axle and the factory cables are held by my two cable brackets. This allow the cables to stay above the axle and leaf springs and to use all the factory K5 e-brake cables and hardware.

    Yeah, thats how I mounted mine as well, do you have any pics of your bracket? It looks like I could almost use a piece of small angle and bolt to the back side of the caliper bracket.

    A line Loc will not pass a safety inspection. You need a mechanical E-brake. If you lose your brake fluid a line loc A) will not stop the vehicle and B) will not hold the vehicle from rolling if you're already stopped.

    I know a couple guys that run them, however you can't use the electrical style like for drag racing. You must use a mechanicaly actuated one, which means either running the brake lines through the cab or having the lever poke through from the outside. We don't have safety inspections here, just smog.

    Unfortunately I don't have pics and I'm in Europe on business. The brackets are built from 1/4" plate (yeah it's a little overkill...) anyway. A piece of angle clearanced around the axle tube will provide a good starting point. If I remember correctly the brackets are about 4" long, the side that bolts to the axle is about 3/4" and the top flat side that holds the cables are bout 1.5" wide. I welded another piece ( I had lots of the stuff) of 1/4" plate to the top of the flat plate at a 90' angle to the e-brake lever. I then drilled a hole to allow the e-brake cable to feed through and stop on the cable stop. I also welded a short piece of 1/2" NPT pipe to this plate. The pipe provides a place to hold and retain the stock caddy release spring on the cable. You NEED to have a strong release spring or the e-brake will hang. The bracket is really simple once you mount the calipers and route the cables. I spent about an hour or so on mine with basic tools such as a grinder, welder, drill etc. Sorry that I can't get you some pictures right now. Good luck!!

    i don't understand why you guys have to fabricate anything, i used calipers off a 79 seville, made my own brackets that mount the calipers the same as they were on the caddy (still out of the way) the bleeder is straight up, the e-brake cable comes over the top. i just cut the ends off the factory cables, pulled them through and crimped an end on them, 20min job, works great and e-z to take apart. ( you must have the calipers w/the e-brake bracket, a dime-a-dozen)

    Did you do that on a 14-bolt FF or a 10-bolt rear end? The later Caddy calipers wouldn't fit over the rotors that I used on my 14-bolt FF conversion. They were 1/4-inch shy of opening far enough to fit over mine. I had to use '76 calipers from a real land barge Eldorado. [​IMG]

    I guess you might be able to get the newer ones to fit if you used half-worn pads. [​IMG]

    The parking brake cable brackets are on my list of things to do. [​IMG]

    i did it on a 12bolt, had to use a caliper tool to get the piston to retract enough to get the pads over the rotor.

    Even fully retracted, I couldn't get calipers from a '78 Seville (the cheap ones) to fit over the 1.25-inch thick rotors used for the 14-bolt FF conversion. [​IMG]

    No, you must use Caddy Eldo rear calipers from 1974-1976 on the 14 bolt FF disk conversion...1978s are the smaller ones used for the 10 and 12 bolt rear disk conversions.

    ya, ken's right, or, you can use front calipers that are WAY easier to get to work right and come up w/a line lock or something

    That's what I thought. The 74-76 calipers with the built-in e-brake are way more expensive, mostly because they're so rare. The later model, smaller calipers are way easier to find. I was bummed that I couldn't get them to work. I lucked out and stopped at a JY that had just got in a '76 Eldorado the day before, so I got a pair that actually worked! [​IMG]

    As for going the "no mechanical e-brake" route... Not where I go wheelin'! Losing your hydraulics on many of the trails in Colorado or out around Moab would result in a truck full of dead people at the bottom of a deep canyon. [​IMG] I want to know that even if a master cylinder fails completely, there's still a cable hooked directly to the e-brake levers. [​IMG]

    Doesn't the FF conversion use 76-78 Eldy calipers?

    The 14 ff uses 76-78 Eldy calipers.
    I was in the hardware store today and I bought two 1/4" thick braces that I will cut down to use for my brackets. I think the braces were meant for heavy duty shelving or something.

    hey to me the brakes are just a back up for granny gear in 4-lo. I still don't think I'd every be willing to go w/out a mech. e-brake.
