Hey y'all!
So, I daily a 1997 Civic EX. Said Civic has a pretty silly problem.

A couple months ago, I decided I'd r&r my front rotors and pads. At some point during the teardown, I realized the old front left rotor was a bit smaller than it's replacement... So I checked the other side, which turned out to be exactly the same size as it's replacement. I then took a gander at the calipers, which were definitely not a matching pair... Ugh. At this point I was a bit bummed out that someone, somewhere, at some point in time was a fool, and now I was paying for it. Oh well, I'll just order me up a new caliper! I decided, figuring it would be that easy.
The following morning, the new caliper was delivered. I excitedly requested some shop-time off the clock so I could get my brakes squared away.
Teardown completed, I grabbed the new caliper to mount it up. Well, as you can most likely presume, It was not a match...
It was at this point that I realized it wasn't just a mismatched rotor and caliper from side to side, but an entirely different steering knuckle. Initially, I wasn't keen on the fact that different trimmed Civics came factory with different sized brakes. Now I am.

tl;dr Though I may now know that different trimmed Civics did indeed come factory with different sized braking components (10.2"/9.4" ? rotors etc.), I do not know exactly which steering knuckle I need to purchase as a replacement. All I know is that I am fairly certain I need an EX steering knuckle.

Any helpful advice will be greatly appreciated!

 

We have a FAQ-your answer is there. Scroll down until you see:

96-00 Civic EX or 99-00 Si knuckle. (51210-S04-N10)

96-00 Civic CX,DX,HX or LX knuckle. (51210-S04-980)

92-95 Civic EX, 94-97 Del Sol VTEC or any 94-01 Integra knuckle. (51210-SR3-N10)

eH.

 

92-95 civic si and del sol si have small front brakes.

 

Thank you both! Sorry for missing the FAQ, I'll look a little deeper before posting next time.

 

Ah, good info!

 

Alright, just ordered up a new knuckle. It's off a 2000 EX. Should be good from what I can tell, no?

 

Wow, baller huh? Ordered a new knuckle.

 

Haha, no, I misspoke. I ordered up a new-to-me knuckle, off a 2000 EX.

 

Fixed

 

Lol, thanks bud.

 

Yes, it will work. Any '96 - '00 LX/EX knuckle will work. '92 - '95 Civic and '94 - '01 will give you alignment issues for anyone else reading this.

 

umm, aren't EX knuckles bigger than LX/DX/CX knuckles?

 

Yes they are

 

Post #3 updated with accurate information and part numbers.





eH.

 

Ah, that would explain the constant pull... Thanks for the info!

 

Sooo, only '96-'00 EX then?

Well, it's a good thing I ordered a used '00 EX knuckle then :D

 

That's only on the dx, cant fit 13's on si/ex rotors

 

Yes. EX/Si front brakes are bigger than the rest of the lx/DX/CX brakes .

The calipers are physically different as well.

They also have a larger bearing/race/hub in the knuckle, I do believe.
