Caboobaroo Posted April 13, 2004 Share Posted April 13, 2004 Is it possible to put rear disks in a gen 1 4wd wagon? Anyone done it? I'm thinking about gettin rid of the drums and swap it to disks. Any clues, suggestions, ideas? Thanks Russ Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 13, 2004 Share Posted April 13, 2004 Yes - I know a guy that has done it. You have grind a little on something I think.... can't recall exactly, but yes, it will work. GD Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 13, 2004 Author Share Posted April 13, 2004 So what all do I have to do? What parts do I need? Just need a little more info on it. Do you recall how did it? Thanks GD Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 13, 2004 Share Posted April 13, 2004 Same stuff you need for a Gen 2 car - disc+hub, caliper, backing plate, and rubber hose...... at least I'm assuming so. Like I said, I've only seen it, but not done it myself. GD Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 14, 2004 Author Share Posted April 14, 2004 Hrmm well I guess I'll have to find a set of gen 2 rear disks then.....What car did those come on? Was it even an option? Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted April 14, 2004 Share Posted April 14, 2004 EA82 turbo cars had rear discs. If you have a 2WD car you need 2WD turbo rear discs. 4WD needs 2WD rear discs. They were never original on EA81s. Quote Link to comment Share on other sites More sharing options...
Hondasucks Posted April 14, 2004 Share Posted April 14, 2004 no, 4WD needs 4WD discs, and 4WD discs won't work on an Ea71 cuz the splines are different, HOWEVER, Jason discovered that the FRONT disc's splines are the same, so that would work, you'd just have to figure out caliper mounting, etc...

GeneralDisorder Posted April 14, 2004 Share Posted April 14, 2004 Yeah - I think that one of the caliper bracket mounting holes has to be ovaled out or something.... just can't recall exactly what he said. Maybe a little grinding too. You'll just have to play around with it. GD Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 14, 2004 Author Share Posted April 14, 2004 well would anyone have a front disk setup that is trashed that I could play around with? It needs to be in kinda decent shape, enough where I can modify it and get it to work before I go and get a nicer set. Just in case I screw up. Oh and I will make a step-by-step process so it can be put in the USRM. So I'd need the calipers and the rotors? Would there be anything else I'd have to get for it?

adaptorraptor Posted April 14, 2004 Share Posted April 14, 2004 I've got a 78 Brat with all four wheel disk brakes. Is this a gen 1? Jim. Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted April 14, 2004 Share Posted April 14, 2004 Yes, that would be a gen 1 car. Do you have pics of your setup? Quote Link to comment Share on other sites More sharing options...
lukr Posted April 15, 2004 Share Posted April 15, 2004 I put rear disk brakes on my 81 gen 1 brat. It was pretty easy all I had to do was grind a notch in the trailing arm for one of the caliper bolts. I got the entire brake setup, calipers. backing plates, hoses etc, off of a 88 4wd xt. Other than cutting the notch it was all a bolt in deal. Quote Link to comment Share on other sites More sharing options...
bajavwnsoobnut Posted April 15, 2004 Share Posted April 15, 2004 hey lukr call me! 971-506-7203 Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 15, 2004 Author Share Posted April 15, 2004 yeah gimme more info on the swap. Where did you have to grind the notch? Can you get pics and a more step-by-step follow up? Thanks a million!!!! Quote Link to comment Share on other sites More sharing options...
bajavwnsoobnut Posted April 17, 2004 Share Posted April 17, 2004 russ I will call you on details but it is a direct bolt on for yours just that you might need to do some modification if things are in the way (read Dremel) Quote Link to comment Share on other sites More sharing options...
subawoohoo Posted April 17, 2004 Share Posted April 17, 2004 well hondasucks just said that ya need the front disks to make it work and lukr, you just said that youve actually did it. so are you saying that you did a rear disk to rear disk swap, or did you use the front setup like hondasucks just said was needed? oh well im nice and confused now. im REALLY lookin into this and would like the info. thanks.

Caboobaroo Posted April 19, 2004 Author Share Posted April 19, 2004 cool Jason, I'll get in touch with you about it Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 19, 2004 Author Share Posted April 19, 2004 Well I just got off the phone with Jason and here is what he said: You use EA82T rear discs for the conversion. He said that all you need to do is bolt everything in and sometimes depending on the car, there is one bolt that will not go in all the way so then you have to grind a bit off of whatever its hitting so it'll go right in. Parts list consists of... calipers, rotors, and all the bolts from it. So now I'm gonna be on the hunt for rear discs and do the conversion, take pictures and have it put in the USRM. I am also gonna be having the front suspension swap, seen in one of my other threads, in there also. Quote Link to comment Share on other sites More sharing options...
v8vega215 Posted April 20, 2004 Share Posted April 20, 2004 you need the calipers, rotors, and backing plate off of an 87ish GL10 wagon or equivelent and you will need to grind a little off the top of the trailing arm to get the caliper on and you will need to grind a little off the botom to get the backing plate down. other than that it is a direct bolt on. you will need to plumb your own brake lines. I got my set up this weekend fron the wrecking yard for less than 40$.total bill was 40$ with trailing arms spindles and head liner and mirrors off the 80 brat that was in there.

Caboobaroo Posted April 20, 2004 Author Share Posted April 20, 2004 So I need a set of rotors, backing plates and calipers for an EA82? Do I need the trailing arms or anything else or is it just the parts mentioned above? Quote Link to comment Share on other sites More sharing options...
v8vega215 Posted April 21, 2004 Share Posted April 21, 2004 just the parts mentioned above and a portable grinder is nice but you can easily get to it with a hack saw and some creativity for the clearance issue. well worth the 40$ in my book.

Caboobaroo Posted April 21, 2004 Author Share Posted April 21, 2004 well went to the j/y today and they have like 4 sets of rear discs!!! Knowing them, they'll prolly want 70-80 bucks for just the whole shibang..... Quote Link to comment Share on other sites More sharing options...
bajavwnsoobnut Posted April 22, 2004 Share Posted April 22, 2004 just the rotors, calipers, backing plates, the lines coming from it (the first and second flex lines and the hard line in between), and the misc. hardware you took off to remove the stuff. If Andrew brings up one of the turbed cars or even the carbed wagon I can point out what I am talking about this weekend or if need be I can try to find some info in some of my repair manuals.
