OEM Front Brake Upgrade for Aus ED

[SPEEDCORE]

So as has been written everywhere.. rear disc conversions for 5th and 6th gens are an easy fix given the RTA is shared between these platforms, and its virtually a bolt on affair.

However I have been having a hard time finding info on what OEM components can be thrown together to get a good upgrade for the front of an Aus ED...

So question is... is it possible to get EK4 front calipers and rotors on the ED, and heres the catch... using parts from australian delivered civics/tegs?

[Snoop_gee]

here is the easiest upgrade i can think of for ED's

the tegs that look like this

was used to end up with results like...

the rotor size difference between the ED and the TEG is significant.

shit looks good^ :thumbsup::thumbsup::thumbsup:

Thanks Snoop..... yeah was thinking that much with the DA teg stuff.. what exactly was changed over for that?

Still was wanting an option to go to the DC teg/EK - 262mm/10.3" rotor.

alternatively, you can do what i did to my ed.
head to ebay, you can pick up a set of pbr xbg semi metallic brake pads for the front + slotted (optional drilling) brembo rotors for $160 shipped. i rang up and sent pictures to brembo and they confirmed that what i received was a genuine brembo spare part.

the only problem you might have is that you have to tell them you need 19mm thick rotors, or they'll send you 22mm thick rotors, which = caliper anchor grinding on an ed.

but if you've got a bit of money to spend, you can get a jdm 11inch rotor + caliper conversion for around $600-700 shipped.

There's a wealth of information on various Honda sites around the world on brake upgrades. Too much for me to make a quick list here.

However, I've just upgraded the rear of my '91 Hatchback (ED) from drums to discs. This includes a rear swaybar. I have just got all the bits to upgrade the front as well.

Shopping List:
Rear trailing arms, discs, pads, calipers, brake lines and Lower control Arms (needed to link the swaybar)

http://i148.photobucket.com/albums/s40/infotechplus/EFHonda/DA9Integra_TrailingArm4.jpg

Rear swaybar plus all linkages, brackets, etc
Front swaybar plus all linkages, brackets, etc
Front knuckles, discs, calipers, brakepads

Brake booster, master cylinder and 4040 proportioning valve

All of these come from the DA Teg.

I've replaced the front discs with slotted DBAs otherwise everything else is used.

I'm planning a complete writeup but apparently I don't have enough rep or points or whatever to do that.

PS. The rotors in the photo above and my DBAs are 262mm. You can actually go bigger to 282 but that requires a bit of mix and match (Accord Wagon calipers/Prelude rotors) plus some drilling/machining that any shop should be able to do.

Thanks for the pics.... that's awesome. Yeah.. the rear is the easy bit :)

Could you do us a favour if you have the ED front knuckles still around... could you measure the difference in length of the upright bit that connects to the upper A arm between the ED and the DA.

I'm wondering about the effects on geometry (mainly camber) if there is a significant difference.

I can measure but it's been done before. The difference is about 1/4" I've read (between the Teg and the Civic) but I'll confirm that. People who've done this setup change have reported no problems and difference is minimal. There are other factors at play here that would exert more influence than the slightly longer knuckle arm. ;)

Test data shows a slight increase in camber but castor and toe are not affected.

Ahhhh now getting somewhere.... if its basically only an effect on camber, adjustable A arm should take care of things nicely.

Yeah I've spent a fair few hours reading on Honda Tech... but could not come across info reguarding this.. and what I did find it was a bit vague.

And yes... I read approx. 5mm taller, but would be good if we could confirm. Only if you have time though.. thanks Pete.

[cristian]

i've got a pair of EK4 front calipers and rotors if u want...

[tseesinngwailo]

Great writeup, I need to do this soon on a friends ED, will head to a wreckers with a shopping list haha, good photos too!

[SlobberGoat]

Another option is the wilwood big-brake kit, which was around the grand mark for the fronts.

[SPEEDCORE]

Yeah.. unfortunately I see that and even the OEM 11" as overkill for what I am trying to achieve.

[barefootbonzai]

building something nice for QR?

[SPEEDCORE]

HAHA nah bro... I've been there done that with SAS. :)

This is a very good article that covers most of the options:

In particular he says:

"The EX knuckles are regarded as the best knuckle upgrade for any EF civic. This is because they don't have any geometry differences and because they were "made" for a civic. The only problem with them is that they are a tad hard to find and become expensive if you want to get them from a junkyard with the brakes attached.

The DA knuckles (also with 10.3" brakes) on the other hand are plentiful, cheap and work great as well. They are, however, a bit heavier weighing in at 6lbs 7oz more per side than a full DX knuckle. Also, because they weren't made for any civic the geometry differences have been blown way out of proportion by message board folks and because of this, a lot of people are scared of the swap. The knuckles are ¼" taller than the civic knuckles but really, it is nothing. It raises the roll center ever so slightly and makes the camber curve a tiny bit more aggressive. So what? Who said the geometry was perfect to begin with? And caster is NOT affected by knuckles. It is determined by the ball joint locations on the control arms. So stop saying the knuckles themselves change/screw up caster! They don't and never will.

You can put the DA calipers and rotors on EX knuckles without any issues.

I have the DA knuckles myself and have to say that I have not felt nor seen ANY adverse effects, even after a full season of autox with them. I even switched back to DX knuckles for a while and noted absolutely NO gain, only a loss in braking power."

I have to agree in that you can easily find TEG setups at the yards but the EX doesn't exist as an Oz delivery (or does it?).

There is no need to go to big dollar $$$ brake upgrades. The whole point of all this Honda interchangeability is that you can build massive and very effective brake setups, even for circuit racing, from stock Honda parts. I can tell you I've outlaid less than half of what it costs to buy one of these kits for the front only, and I've replaced front and back setups with all associated bits inc. master cylinder, brake booster and prop valve, brake lines, discs, calipers, etc.

Shame I can't post any of it up in a build thread though. But here's a couple of teasers:

From my research... there was no USA EX equivalent sedan here in OZ. I could be wrong though as I was basing my research on chassis codes.
EX = ED4 (1.6L)
OZ GL sedan = ED3 (1.5L)

Not sure if the difference in capacity was their reason for throwing the bigger brakes on the EX.....

^ Slight edit and totally agree. :thumbsup:

Top work though.... hopefully you can get a few more pts from other members so you can contribute to the DIY section.

I'd love to post up my build thread and even though I've been on here since 2004 no-one has seen fit to give me a rep point or two for my posts. A couple of points would allow me to get my thread going, with lots of information and links that I've picked up along the way.

I've got my old D15 engine out last weekend and will be progressing to a body refurbish (paint) and interior cleanup (picked up some neat as new ED front seats last weekend), and engine tranplant to D16Y1 VTEC SOHC.

Also looking for a few parts.
