So what is the deal with these? It seems to be much harder to find kits for brackets for these than 60s, i guess it is just a demand thing.

What would the difference be between a 70 kit and a 60 kit?? could it work with some mods or are they too different??

Any options for keeping the ebrake other than eldorado calipers??
 
Not that hard. I put a set on mine. Got the brackets from great lakes off road for around 70 bucks shipped. Went to advance auto and got 1977 k20 chevy front brake parts. The parts cost me around 200 bucks. thats new rotors, calipers, pads, wheel studs, and small parts.
 
The tube OD (bracket ID) is bigger. You could machine it, but that's more trouble than it's worth. The bolt-on kits for the 60s include DOM tube spacers that you have to cut. There are 23 different types of 60s, about something like 6 or 7 different 70s. Instead of making that many brackets, a lot of places just do tube spacers. I recommend getting a weld-on bracket. It's the cleanest and simplest method, not to mention strongest. Not really any e-brake options other than eldorado calipers. Maybe go with K20 calipers and line locks. If you have any other specific questions, let me know - I've dealt with quite a few disc conversions.
 
Line locks shouldn't be used as an e-brake as it is only held by an electrical solenoid, if the circuit or battery fails, so does your e-brake. Eldorado calipers are the only option I know of for wheel mount e-brakes, but I have seen driveshaft mounted e-brakes.
 
Yeah, I agree with you on the line locks not being the most desirable, but if he's not running the caddy calipers, then line locks are the only option, aside from the t-case e-brake. I think that high angle driveline is making output yokes with the disc on there, but they are pricey.
 
Pricey, but less expensive than parking your rig at the top of a hill, and returning to find it at the bottom of said hill, in the trunk of a new Benz because you cheaped out on an e-brake.

I disagree, I have the bolt on brackets, four bolts go on faster and cleaner than welding. no guessing or trying to get it all just right. As far as strength, good hardware, and no issues. All factory disc brakes are bolt on.

Not all line brakes are electric, mine is not(although I have yet to install it. It will be as good as your install, and your brake system

NO the only option. With a manual trans, engine compression is your friend. Not so good with an auto though, another method , and cheap is a big rock under the tire(or two) edging up to a tree( and no, I never harmed one,) or turning the tires into a bank

I also got my kit from Great Lakes Off Road
 
id say itd prob be cheaper to use cable actuated go-kart brake parts on the tcase, then getting eldorado calipers... but there are also other calipers with e-brake such as camaro or f-bird... and i think some companys are offering add-on ebrake setups that look similar to a cart caliper, that mounts at the wheel, but would require an additional/different bracket
 
Upnover, the statement I made about simplicity with a weld-on bracket has to do with all the different variations of 70s there are. There are some companies out there who are making the "do all, end all" kits for the 70s, but there is no way possible that the kit could work on all the ones they advertise, just because of the difference between the axles. Some drum backing flanges are flat, some are flat with a "shoulder" for the backing plate, the 70-Us versus 70-HDs have difference bracket offsets, etc.
 
ok, thanks for all the replies. i am really posting this for a friend. this will be on a street truck, that will see no time towing. I will talk to him about some of the options.
 
line lock?

What line lock will you be runing? If it's a mechanical lock, yes it will work well for an e-brake. All the ones i've seen to this point have been solenoid operated, and will fail in a heartbeat. Would definately be a good option to eleminate the need for high $ calipers and having cables in the way for trail damage.
 
haa a thread about my truck

the application is a 95 ram 2500 with CTD (2wd). complete street truck with performance in mind (a hot rod diesel is what I call it)
