dont forget*

si's were the same as all other hatches, except for the
abs equipet models. I didnt belive it untill I saw it with
my own eyes, but a friends 94si had the same size rotors
(calipers too I THINK) as my 92cx.

92 Si's didn't come with rear discs, they had rear drums.

the 94-95 Si's w/ ABS had the big rotors. If you dont already have one get a 15/16ths master cylinder and brake booster with the civic brakes. youl also need a proprtioning valve off a JDM Integra SiR to run the rear disks, unless you plan on running the full ABS system.

wow..........first off lets clear some of this up before
people get too confused.

if your going to upgrade to a big brake kit, wich
I dont think is needed, I would go for the 1". Its
much better pedal feel then the 15/16ths.

always use the booster that came with that model master
cylinder. Its a theory of mine that they were matched
like that for a reason, but when you start mixing and
matching, you can run into fitment problems, then people
freak out, make threads about it spreading the wrong info.

The very popular 40-40 proportoning valve came on many
cars. For non-abs your going to need the one with 6 lines.
4 for each brake, and two for the master cylinder. Almost
all of them look the same. You have to look at it very close
to see the small stamp thats on the middle where the top and
bottom peice are screwed together and to the bracket with the
tamper proof torx bit. Many cars with 4 wheel disc didnt come
with 40-40's. I have quite a few of them sitting here. Many 30-30's
to chose from.

the 15/16ths are 'matched' to those brakes. I meant the 15/16ths brake booster as well.

pedal feel isnt the issue inspiring an upgrade, its the insane brake fade. I think the 15/16th's is fine, but ive never driven a 1" so what do I know.

Are the 1" as easy to get? How much more expensive?

If its a good upgrade it piques my curiosity.

I have driven both 13/16ths (92cx), a friends
15/16ths hatch with stock 94 non-abs civic si brakes,
and my 92cx with the 1" and gsr fronts and stock drums.

The 1" just felt like a more responsive pedal. I just
figured I was a bit biass and never said much about it
but another member with a good name for himself said
exactly what I thought. I think it was newman not sure
on that though.

I was under the impression that the master cylinder didnt
have anything to do with the actually braking power, or
fade as in this case, but only with pedal pressure and feal?
Am I tottally missinformed on that?

Really its a matter of pedal travel.

The larger the diamter the more fluid it pushes per inch of travel. How much fuid is required for adequate feel depends completely on the size of the calipers and number of pistons.

He just said he was getting Si Brakes, so the easiest option would be taking the MC and booster of the same donor car. the 1" would certainly be stiffer, but on stock Si brakes it might be a little touchy. Turns out he already has the 15/16 from his 5 lug so hes set. wilwood recommends use of the 15/16ths with thier kit anyways. hes getting the fastbrakes wilwood kit though, which uses a smaller caliper then the genuine wilwood kit. So the 15/16ths should work out fine.

I tottally agree that the 15/16ths will be okay, I was just
giving the option that if you are in the market and looking,
dont just be sent on the 15/16ths. But if you already have
the 15/16ths I wouldnt bother upgrading, unless you came
across something bigger for cheap.

How much is the fastbrakes kit anyways? Im not trying to
talk you out of it, or be a dick or anything like that, but im
wondering why you want to go that route? I have pretty good
access to oem parts for decent prices, so I would recoment
just trying to piece together a nice setup with oem parts,
instead of going the aftermarket route, wich usually isnt needed,
but just another bling part. Not saying that you, but just what I
see happen most of the time, for all I know your building a full
race car.

If its hard to get oem stuff in your area, then maybe thats just
easist for you. But that makes me wonder why not just keep
the 5 lug? Im not going to get into finantuals with you though,
im sure you have your reasons for all this, just me thinking too
much past my bed time.

School starts in 4 hrs, and im trying to
save the civic forum one thread at a time.
