Well I've got a bastard 90 STD hatchback with Si front spindles on it, and the brakes just aren't what I want them to be. The rotors are warped and the pads are due for a change.

Here's my big question:

If using rotors, caliper hangers, calipers, and brake pads from a 1991 EX, can you simply bolt it all to the Si spindles without having to find a salvaged 1991 EX to get the whole spindles from it?

Here's why I'm asking:

I figure I can order reman calipers from Honda or Akebono along with caliper hangers and brake pads and just bolt them in.

1991 EX 4-doors are pretty much non-existant here in my area, plus I'd rather have new/reman parts anyways if they'll bolt up.

Has anyone tried this?

 

Never tried it, I did use Da knuckles on my crx though. I now have 90-91 EX Civic knuckles that I am gonna install instead of the DA knuckles.

 

Wont work....even if they do bolt up, it wont work

Find yourself some EX knuckles


You can go with a Fastbrakes kit which bolts on

 

What about DA integra knucles and brakes? The DA stuff is the same as 91 EX.
Any Da's in yor area?

The rotors/calipers will fit on your current spindle. It all looks like it's gonna work until you install the pads. You'll see what i mean

 

Correct me if I'm wrong, but don't the DA knuckles throw the camber off?

I've had two mechanic coworkers of mine use DA knuckles and it threw the camber way negative requiring them to bend the spindles because they did not want to buy camber kits.

?

 

By the way:

Why won't it work? What specifically makes it not work?

Once you install the pads it won't fit over the rotor .

Thanks that's what I needed to know. I think I had just found this out by trying to do something similiar with some spare EG spindles I had here. EX calipers won't fit DX spindles.



Well damn it. I seriously cannot find 1991 Ex spindles here, and I have personally seen how messed up the camber is on the DA knuckles when used on an ED/EF chassis.

Edit:

I suppose me asking why is like someone asking why a B series head won't fit on a D series block.

 

I think if you go with new rotors and decent pads (Carbotech P+) you will have all the brakes you need.

I track my full weight Si on the regular and drive everyday on these pads and OEM rear , no brake woes EVER.

I would also flush the old fluid completely and get something decent in there...

I'm using DA knuckles and I have no problems. I just needed an alignment right after the installation.

The bolt holes that hold on the caliper are further apart.

I understand that, but I'm so used to having a lot of brakes since my other hatch has the Integra discs at all 4 corners with the 15/16ths master cylinder and all.

EDIT:

I run ATE Super Blue in my other hatch, but I'll probably flush all of the fluid out of it and go with the Valvoline Syn Power **** since it has very close wet and dry boiling points to the ATE and it's uber cheap.

 

just making a suggestion

I've measured DA and EX knuckles...the difference was very minimal...like 1/4" if I remember correctly.

The tie rod ball joint location was a little more off, but this won't affect camber; I'm sure it makes a change to the way the steering feels though.

Tom, I can probably hunt you down a set of EX knuckles if you wish. I've probably sold 8-10 pairs here on H-T.

 

So the Fastbrakes kit being referred to - are we talking the ones with the Wilwwod calipers, etc?

This is not my "fast" car so i'm not trying to put better brakes on it than my other hatch.



If there is some sort of Fastbrakes kit that allows one to use OE parts such as calipers, then I'm all ears!

 

If you're already going to upgrade to EX knuckles, why waste additional money on the Fastbrakes kit on top of that?

Get some Accord Wagon/Vigor/Legend calipers, Prelude VTEC rotors and do the small changes necessary to make them work....a lot cheaper!

The standard fastbrakes kit allows you to run Integra calipers on DX/Si knuckles with an 11" rotor...it may even do it with the ~10.2 (?)" rotor.

Damn I didn't know that. Will they clear 14'' steel wheels though?

As far as the Accord wagon calipers on Prelude VTEC rotors redrilled, I knew about that one. That's a mod better suited for my 1992 hatch if I don't do some calipers like Wilwwods, etc.

 

Fastbrakes has a kit with 10.2 in rotors and 4 piston calipers that will clear factory 14 in wheels.

 

Well upon further consideration (from talking with Dr. Cortez via IM) I'm going to try some new stock-sized Brembo blanks at $12.00 a piece and then get some Carbo-Tech pads and do a total flush on the fluid and do the rear shoes and see if that helps.

If for some reason it's not enough, well maybe I'll find some EX front knuckles in the time being.

His best point though was this:

The bigger rotors will take something away from the small engine in terms of roatational mass.

Good point Doc!
