Fabricated suspension arms

[Harrison_Bergeron]

Has anyone on here tried building their own rear suspension arms to run an easier to find disk brake spindle, or a spindle with better aftermarket options than the SEi version?

What about fabbing fronts and rears to fit a whole new lug pattern or to mimic a car with full aftermarket support? The front would be harder as you would need to make sure the axles were compatible, but should still be doable.

The only incentive to doing the front would be the use of unmodified rotors and maybe 5-lug wheels if you wanted, the front brake setup that members here have developed seems pretty nice. The rear setup 3geez members have developed seems like it could use some stream lining though.

Our rear suspension is vastly different from any civic or integra. The closest possibility would be a legend or 93 accord se. Aftermarket for those is worse anyway.

The rear pad size for the SE-i is the same as a 88-96 civic, most integras, and 88-91 preludes. Some rear upgrade kits and larger rotors fit as well.

I only so far have adapted the front Integra Type R front brake rotor,calipers, and pads.

As far as the rears I think Legend master is running front civic rotors on the rears. Check on his setup-build threads.

My only idea is to try and use the drum knuckles and adapt something to that since there popular. But I have not done a thing about it but get all the stock parts.

I've read Legend_Master's brake threads, that is what I was referencing in the original post. The front setup seems flawless, but the rear requires you to first find an SEi at the junkyard, which may not be easy for everyone. The idea of converting the drum uprights to disk is intriguing though.

[Harrison_Bergeron]

Does anyone know what Honda calls the front hub? I can't seem to find them on Rockauto or google.

I am referring to the part that holds the wheels studs that the brake rotor sits on.

[Joay]

Edit: wrong end.

Not the knuckle?

[2drSE-i]

Also called the spindle. Rockauto won't list either of these parts though, because they are unnecessary to replace. Unless your trying to upgrade, but they aren't really worried about you drum brakers

The wheel hubs are the same for all 86-89 accords, disc or drum.

[Harrison_Bergeron]

Thanks, all I saw was rear, I seriously searched a bunch of different models for over an hour and found nothing.

My first upgrade project is going to be trying to find a simpler disk conversion for drum folks, and I am researching the cost and benefits of doing a 5 lug conversion as well.

[Harrison_Bergeron]

Does anyone have a pic of the SEi rear knuckle next to one of the drum rear knuckles? The diagrams here show them looking pretty much the same, which I know cannot be true.

The only way to do this is to make a plate that will bolt in place of the drum backing plate and have threaded holes and a recess for the caliper. The plate will need to be pretty thick (at least 3/4"), have a recess for the mounting surface on the spindle, and have some shaved off of where the caliper bracket mounts. The mounting surface for the caliper bracket would need to be at the same level as the mounting surface for the backing plate/dustshield on the spindle.

It's definitely possible but it would be much more cost effective to find a set of SE-i spindles. There wont be enough interest on here to offset the machining set up costs either. I personally have 4 sets and have seen many more. They're not that hard to come by.

[Harrison_Bergeron]

I kind of figured I would use the backing plate mounting location, I have ideas on how to make the plate simple, but until I get my car or at least see pics of the stock setup my ideas are not worth putting out there yet.

Why do you say that they bracket would need to be 3/4"?

From my few days on here I think that if the plate could be made simply enough it would at least beat the dizzy adapters in units sold. (I can't believe I read that whole damn thread)

Even if the final product is not marketable I am confident I could get it to work for my own car.

[cygnus x-1]

Interesting project. Just from reading this so far and looking at the diagrams, my guess is that it probably would be cheaper to just get the SEi spindles. But if you do have some ideas for making some sort of adapter I would be happy to help with simplifying the design to make it cheaper/easier to make; regardless of whether or not you ever have any parts made (be me or anyone else).

i'll believe this when i see a screen shot of the paypal account that the money's been paid into lol... i'd be interested in seeing the design and finished product.

how were you figuring on using the existing brake cables or were you planning on using the sei brake cables?

[Harrison_Bergeron]

Do you mean emergency brake cables? If so, then the plan so far is just to use SE-i ones, I think they were like $20 or less on Rockauto, but I would probably look into trying to make the stockers work, I doubt they would though.

Does anyone have a pic of the drum brake knuckle?

Are the knuckles cast or forged? If they are forged then I'm thinking that at the very least the bracket could be welded on for my own car, and maybe sell the lasercut brackets to folks who have welders at their disposal.

Again, this is all just brainstorming, I am confident that it can be done, but my ideas on how are all based on info I've gathered from the internet. I should have my car by the end of next weekend, that is when the fun will really start.

its not that hard...can be done with the right tools in a couple of hours...i did mine the day after x-mas in the cold driveway...haha

[stat1K]

i'm sure he knows HOW to swap brakes, hes saying it's hard to FIND said brakes. He's also talking about using the existing drum hardware so you don't have to find the sei rear trailing arm and brake assembly, so did you use your existing drum knuckles and fabricate a bracket to go disk brakes messy? (read sarcasm).

i love how this is the millionth time you've posted what you've done to your car with little to no regard as to what the OP is talking about.

as for my question, yes i was talking about the e-brake cables. I would avise against rockauto's brake cables as from what i've seen they are pieces of shit. if you could find stock ones that would be ideal in my opinion but i'm not even sure if they're available from the dealer anymore as the 1989 is now more than 20 years old. It's my impression that the dealer will no longer order parts from japan when the car is over 20 years old. I've been told this by several dealers, in which case the rock auto ones may be the only resort.

[Oldblueaccord]

I would lean towards a setup thats easy and affordable to find parts for. I don't think the SEi rear calipers are that cheap without looking up anything.

As far as how many would be interested hard to say. I think I had had 2 pms about my front brake setup in the what 3 years I have had it posted so me getting brackets made or putting a kit together would be a not for profit deal.

My starting point is going to be to try and get 2g (same as non-abs 4g?) Integra rear brakes, rotors and calipers, to bolt up. We use the same rear hub, and the wheels from an Integra fit a 3g, so it seems like rotor offset should be easy to work with.

First I am going to try and devise a bracket that is just a flat laser cut piece. That seems like a long shot, so plan B is to try and make the bracket just a flat piece with bungs for caliper spacing welded one. I have a plan C and D that involve bent base pieces and bungs.

The prototype will just be made in my garage from scrap and will go on my car, if people are interested I would then start worrying about laser cutting and a jig to production weld them.

[LX-incredible]

Good to luck trying to weld to the casting. You will not be able to use a simple flat bracket without spacing out the rotor or using a different one. With a different rotor you may run into the issue of caliper to wheel clearance...

[Harrison_Bergeron]

I wasn't sure if the stock knuckle was cast or forged, some pics looked forged, but cast seems more logical.

Shouldn't the caliper to wheel clearance be fine, if an Integra uses the same hub, and a 3g can run an integra wheel, then shouldn't that mean a stock integra caliper on a stock integra rotor should clear the wheel fine? The issue seems like it should be the clearance on the back side, whether the rotor contacts any thing on the knuckle side.

This is promising, in that pic it looks like the tab for mounting the caliper on the SEi is flush with the holes for the drum backing plate/dust shield. This makes my ideas look even more realistic. I can't wait to get my damn car.

On the SEi, does the caliper bracket mount on the tire side, or body side of the tabs on the knuckle? In other words, is the knuckle threaded for the caliper bracket bolt, or is the caliper bracket threaded. In the diagram below, what does bolt #34(top right) thread into?

I think I should point out that the 2nd gen Accord drum knuckles have a factory, bolt on disc system available to them.

The 2g Prelude and 2g Accord share the same rear knuckles, drum or disc. So the Prelude disc's bolt to the Accord knuckles. Comprendez?

If Honda already made up a bracket to do the conversion on the 2nd gen, why can't you do it on the 3g? And it certainly doesn't have to be .750" thick, either. Drum brake backing plate is, what, .050"?

Hell, maybe the 3g disc and drum knuckles are the same, and nobody noticed.

And nobody is going to be doing anything stupid, like welding cast, either.

rough idea of the hole spacing etc.
