may have found an interesting brake upgrade...

[Hash_man_Se_i]

Wow, im excited. But which AEM rotors would I need. I think this would be an awesome upgrade.

Civic

I've got an extra set of calipers for this and other swaps I think I've figured out. If you have an 88-89 Lxi or any Accord with the same brakes, I'll drive up to 3 hours from Knoxville, TN just to see if this really works.

How about CT??

[Hash_man_Se_i]

What kind and year of civic rotors do I need??

And I may try this upgrade once I have more money, and power.

[Immeraufdemhund]

hey i live in KNoxville TN. and i work at advance auto parts...so if you wanna go throuhg me i'm down with it (a nice 20% discount is a positive thing. and if you dont have the caliper right away i can wave that charge and wait for you to bring them back. I work in or near fountain city... (accross from krispy cream) I"m Robert. See me their

my number is 865 607 6051 call me if you want.

[guaynabo89]

too bad you don't work in Florida

[Immeraufdemhund]

ok i just called stacy on chapman highway advance. And for 2 rotors and both driver and passanger front calippers it would be like 90. (73 with my discount) without the cores being added. I looked up a 89 legend. Is this correct?

also, since i have a 87 lxi. Do i have to upgrade my master cylinder to a 89 accord/ 88 prelude? (i looked up the two and they are the same)... they look very identicle what is the difference between the two?

[guaynabo89]

No, we are looking for the Acura Legend 94-95 GS edition 2 or 4 door don't matter.

[RobT5580]

The kit is for Civics/Integras dont remember the exact years but i know 92-95 civics were included and i think tegs up to 2000 or so. The upgrade is expesive as it runs from $350-$400 and then you have to modify the brackets for the accord because the AEM ones are not thick enough. I had custom made CNC brackets made up and provided all the hardware (except rotors) and i had 3 kits made. Everyone wanted them but only 2 people sent money so that will be that last time i do that. The proper Bolts for this setup are very expensive because the mimimum quantity to order is 50 since they are a high strength metric thread. I tried a half dozen places and nobody had them so i had to order $130 worth of bolts. But i figured i would have sold atleast 10 kits but it never happened.

Anyway the brake upgrade is very nice and was worth the money next i will try the caliper upgrade if i dont get 4 piston Porsche calipers since i can get them for cost. But that will require a new bracket to be done on the CNC.

[Immeraufdemhund]

95 Legend gs caliper both sides 52.99 each (2 needed)

(for 86/87 lxi people)
89 perportional valve: (says i can't order it)
89 rotors front: 18.88 (wearever) each
89 rotors back: 19.99 (raybestos) each
89 steering knuckle: (umm.. what's the real name for this)
89 rear calipers passenger: 80.49 (a1 cardone)
89 rear driver calliper: 96.99 (a1 cardone)

I still dont know which rotors though, so i just guessed and put the 89 stock front and back ones in the list)

[guaynabo89]

Pretty good price on the legend calipers. Thats about how much I can get them locally.

[racerxh23]

Sind sie Deutch oder Schweizer?????

Have you done the swap? I'd personally go with an adjustable perportioning valve since your spending $$$ on a stock one anyways. Testing on on my Prelude has shown that the front/ rear bias is off by up to 15%. If you include the safty margin Honda built into the system for grandmaw, thats allot of room for tweeking.

Are you talking caliper brand or something.


racerxh23:

Do you happen to know if the master cylinder off a gs lagend will bolt up to an Accord or any other car for that matter?

I've been thinking the stock Accord one won't be able to push as much fluid that is needed for the dual piston calipers.

[Immeraufdemhund]

sind sie deutch oder schweizer (are you german or swiz (i think))

neither i'm in the states...well i suppose i'm deutch atleast my family line is.

yah i was wondering about the master cylinder also. Can i upgrade or do i have to with my 87 lxi goto the 89 sei master cylinder. cause the 89 sei is the same on the 88 prelude si. and that has 4 wheel disc.

ok i looked up the master cylinder for the 95 acura. and it has 3 threads. red, gray and green. It's also on the left side. I"m talking to dude at advance and he says the third thread could be for either my clutch (for hydrolic clutch) or abs. I dont konw which. does this thing have abs. either way can i just cap that one off? the bolt pattern looks the same. and they say that they have one over at clinton highway (for all yous in knoxville TN) So i'm going to run over there and check it out. is it a pain to switch sides though for the brakes??? here's a link to the site [link] http://www.partsamerica.com/PartDeta...pe=230&PTSet=A [/link]

tell me whatchas think

[racerxh23]

The biggest mc bore Honda makes is 1". The Prelude 92-01 I know has 1", the '95 Legend GS has 1", The Integra, and also the NSX. As far as I'm concerned the bore isn't that important in our case. A smaller bore you'll have higher line pressure but more pedal throw and a bigger bore you'd have the opposite. I tried finding an ideal pedal throw and line pressure, but then the pedal ratio and booster come into play. I've been playing around with this idea for a while but the booster has me stumped. It all comes down to either redesigning the booster or finding a way to increase vacuum (which I'm working on). Changing the pedal ratio is tricky too. The mc pushrod can't angled more than 5deg. That leaves very little room for adjustment. However that little bit can make a big diff. This is something else I'm working on very slowly. Take a look at how the petal is mounted and tell me you want to mess with that!


In short if the mc is atleast 15/16", I wouldn't worry about it. If you have rear drums I'd go with a 4 wheel disk mc. I really haven't looked too much into mc bores on the Accords. If you go to Advanced, ask to see their reman brake parts book. It the best thing I've found so far for cross referencing.

I thing the grey cap your seeing is actually a plug. I'm not sure what its for but I do know no fittings get attached there. I'm thinking its so you can disassemble the mc for a rebuid. Yes it has abs but it doesn't effect what we're trying to do and no you don't need that mc. Infact, I don't even think we could use it due to the fluid cups angle.

Immeraufdemhund: Do you want to meet up with me tomorrow? All this talk has me amped and I'd like to find out once and for all if its possible and what the possabilities are. Hit me up on aim under highspeed155.

[guaynabo89]

I'm mot to worried about master cylinder either just wondering about matching up the whole brake system to gie it a natural feel.

I mean the Guys who upgrade to 4pot Wildwood, Brembo, SSbc, and aem don't change the master cylinder and I havent read any complaints yet.

[Immeraufdemhund]

hmm.. well for giggles i went and got the mc from advance on clinton. It's a mirror of ours, but i believe it will work. I cut a piece of alluminum and mounted it to that and i'm going to mount the alluminum to the firewall. The back brake line on the legend is 12-1mm and the front is 10-1mm. ours currently is 10-1mm for both. So i'm having fun with that. I'd like to get together someday, dont konw when. If you could give me a call that would be great too. I want to put on rear disks for fun but that will take some pieces-parts finding. I'm going to read the how to on how to put on the rear brakes so i know what pieces to find..... what is the difference in MC on 86/7 and 88/9. Cause they have different part numbers, but i have no clue what the difference is between the too. They look the same, feel the same and weigh probably nearly the same. I'd like to use those with the legend rotors, unless i can use the lude ones. I dunno it's goign to take some playing around.

Oh yah i havne't used aim in soo long. Give me a call, that would be quicker, i'll hit you up with a pm so you hvae my number.

The 88-89 push more fluid.

[2old_honda]

You wont be able to use Legend rotors because they are 5 lug (unless you re drill them) Same goes for prelude rotors, they will either be 5 lug or they will be the wrong bolt pattern (4x114.3 i think)

*thinking out loud*
I wonder how big integra rotors are? Probably a little bigger than the accords but not enough to make a difference.
The earlier JDM integra type r's (95-96 i believe) did have the 4x100 bolt pattern and bigger brakes than a regular integra. I wonder how big they are? It would probably be a bitch to find a set.

[Immeraufdemhund]

I looked at 89 rotors yesterday and 87 rotors. 89 are bigger. Then i looked up the two calipers and the 89 is larger, taller, and has a larger piston. I believe the mounting is different, but i'd have to pull it off to find out. so more fun at advance for me i guess till i get this figured out.

Oh yah i also have my acura mc installed. It works, but there is more pedal throw now. I think it's just cause i have bad fluid in their mixed with a little air. Fixable maybe. When i switch to 89 and acura calpiers i'll blead it better. And then final adjustments when i switch to rear disks....

[guaynabo89]

Yes it is. The bolts are set farther apart on the 88-89 Accords.

That also means if you have an 86-87 accord youll have to upgrade to 88-89 front spindles before you can go with an AEM big brake kit.


As far as your master cylinder....you do realize that this upgrade we're talking about is using the 94-95 Acura LEgend GS dual piston front calipers, not the earlier models or anything other than a GS model.

[Immeraufdemhund]

yah, i found out though that the master cylindar isn't all that important for htis upgrade, but i wanted ot see if i could put it on their being a mirror and all. I grabbed a mc off of another legend in the 90's and it mounts the same as the accord, but has the brake lines fed on the other side of the accord mc. So i should have put that one on if i was goign to put in a legend mc, but you live you learn. I'm waiting to get some more money so that i can go get the new upper control arm so i can fart around with the 89 stuff... i want to upgrade my rear ones first before i do the front ones.

Question can i put on the 3g prelude rear arms without playing around with it too much, or was that what that one FAQ was saying? I was a bit tired reading it and so i wasn't too sure if i was reading it right or not.

[Vanilla Sky]

hmmm... bump... i'd like to see an update to this...

[Slavic]

What I'd like to know is why is everyone so stuck on large rotors and no one is talking about getting an anti-lock brake system hooked up? I mean anti lock brakes were actually an option on 3Geez.

What are bigger rotors going to give me? More ability to quickly and easily lock up the wheels? I'll pass on that thank you very much. I'll take an anti-lock brake setup with drum brakes if there was such a thing before I'd spend money on larger rotors and better calipers so they can lock up on me instantly so I can slide into the rear of a lexus in Miami rain.

Does anyone know if I can hook up a 91 Legend anti-lock brake system to an 87 or 88 LXi and how?
