KA7 Legend Brakes SWap?

[cyra]

I found on b-ht.com, that some of the civics they turboed have a KA7 Legend brakes ( double piston calipers). Since Accord of the late 80´s is similar construction to civic, did somebody tried this swap on Accord? Thx

you can use the calipers, you just need discs that fit. they are supposed to be 23 or 25mm thickness I believe. You can use NSX calipers as well, their bleed valves are not upside down like the legend calipers.

Doesn't it depend on your model and year of Accord? I thought the 88-89 LXi brakes were different from the rest... Of course you can always swap the spindles over I suppose. Don't the 86-87s have to get the JDM F1 edition calipers if you want twin piston goodness? Those calipers also fit the 2g Accords as well.

[thegreatdane]

yes it's the 262mm brakes that can use prelude/itr/legend/nsx calipers

So these fit the Accord caliper holder, ok..... and Accord main brake drum and power assist, will this fit to these calipers? the hydraulic ratio etc?

my si exclusive has the two piston calipers as standard, not sure of the rotor size tho.
might be worth investigating a set of those unless the legend rotors are heaps bigger.

Well, that is because you re lucky new zeeland b*****d :-)
Here in europe we have nothing from these JDM delicates......

Looks like I am going to visit our local Honda junkyard and compare ....

if i remember right the "stock" twin piston calipers have the same size rotor as the 86-87 lxi-s

That's right.

This is why the 2.0Si can have 13 inch wheels. I always wondered why the top of the line Accord in Japan came with stupid 13 inch tires. The 88-89 lx-i/se-i has to use 14 inch tires in the front, the 13 inch won't clear the caliper.

and here i was thinkin that i had a good brake package
mind you it does stop pretty dam well with just semi metalic pads
not going to worry bout bigger rotors, just after market slotted/drilled replacements and flasher pads.
anyone tried grafting on gen 5 sir brakes?
could also be worth a look

[carotman]

Well, the JDM Accord has twin piston calipers so the pressure is spread alond the pad. This gives a nice advantage.

Like you said, just get better pads

I also thought so but recently I have found out that early type JDM Si has smaller rotor for 13inch wheel and the later type Si has larger rotor for 14 inch wheel. But the calipers are the same.(pads are the same size as cab model's!) The knuckle are also different to relocate the caliper.

Hope I'm not dragging things completely off topic.

For wild brakes I read something about the top spec. Rover/MG ZS180? (Euro Accord based floorpan) disc rotors having 282mm Dia (15+ inch wheels ) with 4x100PCD [& also 260mm rear!] that could be paired up with matching MG/Rover calipers or with slightly modified Legend Calipers for use on '90- CRX Vtec/SiR.
(25m thick compared to 23mm Legend, not sure about offsets though)

Might be worth investigating for those in Europe able to easily order those disc rotors just to save having to redrill Legend items.

Apparently MG ZS120 still had 262mm, 21mm thick discs shared with '90- CRX Vtec/SiR (different offset & knuckle/hubs from std 4g Civic).

Unfortunately you can't read the forum without joining up though:

And it goes on forever so I hope I'm not misleading everyone after only having reread the first page.

the only disadvantage of the accord twin piston calipers are they stop good, until you wanna stop good 100 times in 15 minuites then your rotors get all red hot and you brake pads catch on fire and melt the center cap out of the center of your wheel lol

have thought bout that
brake ducting
piss easy to do
