custom 4wd rear disc conversion

So it looks like you don't have to hack the rear trailing arm. any thoughts?

    Sounds interesting. When i did the rear rotors from my 93 sol SI that I had. I dont remember seeing splines on the rotors. So what do the axles bolt to? I have not taken the rear apart yet.
  • ricefighterricefighter Wagonist
    wow as in wow. im been looking for a bracket for sometime now and this is a welcome surprise. i was thinking of using the ep3 2002 2003 rear rotors. the reason being is that its 10.3" compare to teg's 9.something. i just dont know if the ebay brackets will be the exact measurements for the rt4wd rear disc conversion. i will surely be happy if this works with 95 teg rear caliper. that will be awesome.

    okey we need more inputs here people. put some good ideas.

    85$ is a little steep for some laser cutting and some welding. But now that I see how the brackets are, I meant tear apart some rear brakes this weekend.
  • skinnyskinny Senior Wagonist
    keep us posted. we may just all have rear disc befor the end of the summer 8)
  • ricefighterricefighter Wagonist
    how about we could do a mass order. maybe somebody can make our rt4wd rear dics bracket. i would recommend ep3 2002/2003 rear disc since it is 10.3" (same offset as teg rear disc only bigger)and teg caliper( maybe DA 90-93 or DC 94-00. just my suggestion.

    With the ep rotors you won't be able to fit the rt rims. I'm gonna get the rear calipers and disc and try to bolt them up and see what's up

    i beleive 14's will fit coz DA tegs are 14's oe. tegs oe front rotors are 10.31 inches. my fronts rotors are DC tegs and im running 15's so im okey. if i can do ep3 rear rotors/95 teg calipers, ill upgrade the fronts to prelude rotors/legend caliper combo.

    ill wait for skinny's rear brake investigation. thanks in advance :D

    Well slap me and call me a bitch :lol: so I'm wondering if the mounting holes for the brackets will be there. I they are it should just be a part swap. I love how the guy on the site doesn't go into detail it just says there from a del sol. No custom fabbing or mounting that I see
  • evol911evol911 familEE
    FYI: Don't forget if you swap discs onto the rear you have to get a 4 wheel discs proportioning valve.
  • skinnyskinny Senior Wagonist
    I never did with my crx. it had DA fronts and 93 si rears. I think this time around I will try the valve and see what the fuss is about.
  • Old SkoolOld Skool Council Member
    The proportioning valve is not required.. I have the stock one on my '79 wagon with 12.3" fronts(Custom hats and Willwood rotors) and 11.1" rears (re-drilled type R front rotors) and Acura legend 15/16" master and accord booster. I'm going to do a similar swap on the '89 this summer.. I also made up brackets for the nsx calipers (front and rear)
  • evol911evol911 familEE
    From what I understand, the front disc/rear drum prop valve is heavy on front braking, while the 4 wheel disc prop valve evens it out a little more but as always most of the braking is on the front. The prop valve probably isn't that big of a deal but if you are swapping rear discs on then might as well make them do some work.

    I'm interested in the difference between running a brake booster or not, anyone have some insight on this?
  • JakerJaker familEE
    Those Ebay brackets use the bolt holes that mount the drum brake backing plates onto the drum brake hubs.

    Here's my setup. It really was not that difficult. Unfortunately, it won't transfer over to the RT4WD in it's OEM configuration, since I'm using CRV rear hubs, ITR calipers and the 2 piece rotors. The rotor hats don't place the rotor in the same place as an OEM rotor's hat would. Rotors in my case are 10.75" Wilwood off the shelf rotors that I had turned down to 10.25". The hats are also an off the shelf item from Wilwood. These are the same as the ones I'll be using on the front, but my front rotors are not turned down (full 10.75") and they are cross drilled. The rears will get cross drilled once I get the car up and running, and sort out all the bugs (not a high priority right now).

    It took me about 2-3 hours of thinking, measuring and massaging to get this setup to work. I also spent about $100 at the machine shop to get them to machine the brackets "nicely". I could have done it myself with an angle grinder and a drill, but then they would have turned out quite ugly. I started with a 1/2" thick piece of aluminum plate, and went from there. I think most of you guys could figure this out for yourselves, and if you had a welder and some time, you could make them yourself out of steel plate. The only issue with my setup right now is the E-brake. The OEM setup for the cable does not clear the trailing arm. As you all know, the Wagovan trailing arms are quite different from the hatchback, CRX, etc... arms, as pertains to the part that goes up to the upper control arm. Well there just isn't room for the E-brake cable bracket to hold the end of the cable via the OEM routing. I'll sort that one later on as well.

    If you go with the 10.2" EP3 rotors, you'll also need to use the ITR or EP3 rear calipers, as the larger rotor will require the caliper to be further out from the hub, and the ITR and EP3 have that extra distance built in (for obvious reasons). If you're making your own plates, that no big deal (you don't need the ITR/EP3 calipers), but if you go with the Ebay brackets, you'll need the different calipers.

    I hate to have to ask but can you get us pics of just the bracket it self? And LOTS of pics please

    Jakers brackets won't work, he's using CRv hubs.

    Jakers: Are your trailing arms cut and welded? Looks like you had to splice the front of the wagon to the rear of the CRV? I can't tell if they are welded together because of the paint. It looks like they are just trimmed for wheel clearance.
  • JakerJaker familEE
    They are RT4WD trailing arms that were "clearanced" for big tires, and the front of the arm has been cut off, as I will not be using the toe control links. If I get time, I will take it apart to take some pics, but when I assmebled it the other day, I told myself that it would be the last time it was apart till the car is on the road. I've had it together and apart about 60 times trying to get things just right.
  • ricefighterricefighter Wagonist
    jaker thats a tight rear disc conversion there and thanks for the input. i have to figure out how to do mine.

    skinny waht kind of rear caliper are you gonna use for your wagon? and also what disc are you planning to use?


    wagon..................4ever.............
  • skinnyskinny Senior Wagonist
    Da all the way. there are a million of them at the yards around here. Im hoping to some how have a bracket made that will hold the calipers in the stock locations but bolt up to the RT4WD drum arms. If im comprehending it right, the rear axles bolt into the hub itself. then the rotors or drums sit on top of the hubs. The website posted isnt really descriptive about his swap short of its del sol parts. Jaker said the eBay brackets from ebay bolt up to the holes that the drum plate mounts to. If that will work I would rather buy the eBay ones. If I cant find them then its custom. My wagon is my DD until the weather hits a solid 75 so I cant have it down for long periods for fabrication, test and fit, mock up, and final assembly.
  • noahrexionnoahrexion Wagonist
    Skinny I am actually planning on doing the exact same thing as you are. Although I was planning on trying my hand at making some steel ones (and also possibly welding them to the hub too). These ebay ones would be great to test fit and see how things go. I would also go DA all the way; there are always 5+ in the yards. I've got the DA fronts and a 15/16 BMC waiting for my rear disc to get underway.

    I like you will need to wait till the weather gets consistently nice(r) since my motorcycle/bicycle will be my transportation when its down. If you start this please keep a good record of it so we can all benefit. I will definitely be doing a tutorial for mine (like I did with the DA knuckles) when I start. 8)
  • skinnyskinny Senior Wagonist
    will do. I will also share info with you and maybe we can get some custom brackets made for our fellow wagon lovers. I have been trying to find the ebay ones but im having little luck. could be im getting distracted every few pages. If you can find them post up a link so I can get a look at them. I went around and talked to people and I was told $50 at most if there being made from scratch. If I can get the ebay one and take it in it will be considerably less.

    If it was at the meet we had at Edgefield then no, but I can tell you what kind of beer I was drinking. Sleepy Hollow Honey Nut Brown Ale - check, rear disc conversions - doesn't ring a bell :lol:

    You are gonna have to nudge my memory Andy but as far as the adapter plates it looks like simple work to make your own...

    Oh yeah! Front suspension will go on fine, noahrexion just did this so check out his thread as for the rear with this adaptor plate, I'm guessing it would work, you just have to make sure you have the right diameter rotor but as for calipers they will work.

    I hate to be the Grim Reaper. :twisted: The Ebay brkts won't work. :( One observation is there's NO splash shield.The biggest reason they won't work is caliper placement.The Ebay brkt w/4 holes are for '93+ which have their caliper at the rear most position.It works 'cuz the LCA are set more forward . The Wgn. is set further back(clearance prob).

    The slotted Ebay brkt are for Post '93 .If I remember right this is also the reason it won't work on the Wagon.The upper trailing arm is at a different angle .For the Wgn. the caliper angle needs to be changed.This doesn't mean we can't use this idea.The eBrake won't clear.Looking at the left rear brakes.All the rear Wgn.rear disc conversions I've seen have the caliper at the 2-3'o clock position.If you look that the following link.Click on to the 1st link on my 1st posting.What he did was to bend the H :evil: LL out of the eBrake brkt.It's a poor pic:
    viewtopic.php?f=8&t=2247
    A different caliper will be done differently.All the Wgn. probs as far as the disc conversion are caliper related.
  • ricefighterricefighter Wagonist
    can anybody has access to a cnc design a bracket for our waggy? i am thinking of something like a 2002/2003 ep rear rotors ( since its 10.3" in diameter) and teg rear caliper (maybe from 90-93 or 94-up since theyre comon and has a lot of aftermarket goodies. maybe all we need is the bracket and we can mod to fit to our trailing arms.

    comments,reactions,better ideas are welcome.

  • JakerJaker familEE
    I think you could design 1 bracket for the 4WD and 1 bracket for the 2WD, and then all you would need to do is pick your caliper to match your rotor. The EP3/ITR/TSX caliper to go with larger rear rotors,and the 90-93/94-01 Teg caliper to go with the smaller rotor.
