What BB, MC and Prop valve will swap into my 93 civic hatch with the least hassle? I have read a lot of contraversoy over what works and what does not. Thanks.

pdiggitydogg

all civic and all integra units

=GAME=

i got the mc/bb from a 92 integra LS in my eg. bolts right up without bending any hardline. its a 15/16 as well.

non-abs. I thought explained what you needed in your last
thread......

pdiggitydogg

my chassis is non
and my bb/mc is abs
no problems what-so-ever

func-tion

Or you could go a step easier. Leave your brake booster alone and do this.

its not a problem at all, if you want to re-flare
one of the lines going into the mc. Its not hard,
but some people get scared off. I hope your not
trying to tell me that you can use a non-abs flare
nutt with a abs mc. If so your wrong on that.

And that may be easier, but easier isnt always better,
or cheaper.

The poster of this thread is looking for info on boosters,
not what master cylinder he can bolt up to his booster.

My thoughts are if your going to be replacing the booster
why not get a new mc while your at it. I dont know the
price on a new booster, but I bet you could get a used one
for cheaper, and if you really wanted to you could rebuild it
with one of those 10$ kits they have. Im not sure if you can
re build the booster, but definatly the mc.

i did this. its a '99 gsr bb/mc combo (abs) on my '95 dx hatch. its all bolted together, and works fine, no leaks. All i had to do was bend the lines. No reflaring anything. I've had this setup for a few months now.

is a flare nut the brass nut that holds the flared brake line in place? if so, putting the stock civic (non abs) flare nut into the abs gsr mc felt completely normal, the same as every other nut i messed with (at the calipers, at the prop valve).

elwood

Well you guys are the exception I guess.

I have a few compleate abs systems sitting here, and on the master
cylinder one of the holes is much bigger then the other.
Makes me think that you guys arnt really using abs
parts. I didnt belive it either, got into a bit of an argument
with tom about it, and like always, he was right.

A abs master cylinder wont bolt up to non abs brake lines.
Belive it or not, I could care less. I know I am right though.

edit- yes the flare nut is the brass nuts that the hard line goes
through. I forget if its the front or the back, but one of them is
bigger when dealing with abs.

pdiggitydogg

I didnt reflare squat and its just dandy

itr mc is abs (standard)

elwood

If you didnt have to re-flare, then its not a
abs master cylinder. Search for it, you guys
are wrong, im sorry, your just wrong.

abs to non-abs master cylinder fitment

emerika is a certified honda technitian, but what does he know.


again, you are wrong

tonyXcom minght not post here as much or ever anymore, but I would take his
word for it. He had to do exactly what im explaining.

i really don't think we're wrong, but there definitely is something weird going on.

I pulled the mc/booster off a wrecked '99 gsr myself. It definitely had abs, the whole abs unit was there, along with the "fake" abs prop valve, along with abs lines to the brakes (i took the rear lcas/sway bar), etc etc.

I'll post a pic of the bent lines and where they match up in a minute to prove that it is indeed an abs mc.

is it possible that yes, one hydraulic line IS larger, but doesn't really require reflaring? meaning, the proper way to do it is to reflare, but maybe we're just getting away with not doing it.

edit - i just read that 2nd link, and there is no way that what i just said would work, because of the 10 vs. 12 mm flare nuts... so i guess that rules out that theory

carsaregood

ok, here's the pic for proof. '99 gsr abs booster and mc from the same car. i bent the lines to fit, its not pretty but it works. Again, i did NO REFLARING. The line on the left side of the pic went on the opposite side before bending.

I'm not sure how you can tell the year a bb/mc combo comes from, but one thing i've noticed is that the ears of different years are oriented differently. the mounting bolts of this one go straight across, parallel to the ground. like this ---. I have an RS 15/16ths that goes like /. my stock civic 13/16ths goes like \. i don't know why they made them differently. anyway my point is that maybe that can tell you something about the year they are.

I think there is a lot of misinformation floating around, especially about brake swaps, so I'm just trying to get things all sorted through. For example I read on ht that you can bolt up any integra mc to any integra booster, but its not true. For one, the orientation of the mounting ears i just mentioned above. For another, I have tried using an LS BB with the RS mc, but that did not work. It "worked," but not really. What i mean is that the brakes operated, but gradually the brakes would lock up, the more i used them. It came to a point where i had to pull over at a gas station, and my motor could not move the wheels. I had to open up a brake line to release the pressure, and that fixed it. But it would happen over and over, so I think that the piston inside the mc was maybe getting getting pushed in crooked, causing it to not return to the non-braking position.

crap that was a lot of rambling about stuff not relevant to this topic..

me too...

toEknEEg

on my 92 Cx, i used an RS brake booster and master cylinder. i didnt bend any lines and i didnt reflare any of the lines. search for topics made by me... i just did a how to.

What about just having my civic dx brake booster rebuilt (from a trustworthy shop) and use the 91 civic ex mc (15/16). How do you think this would be with my slotted rotors, hawk pads, teg front discs and teg rear discs?

I think I am going to pass on the 40/40 prop valve because I don't want lock up and I don't like too stiff of a brake pedal.

elwood

That is very strange. Im thinking that maybe honda went
back to using one size of the flare nut deals. You seem
to know your ****, so ill take your word for it that it did
have abs. Ill have to keep a look out for that. All of them
that I have seen have had the bigger nut, and I have looked
at a lot of them, maybe just nothing that new though.

carsaregood

elwood - yeah maybe thats it, maybe its year dependent... this is kind of frustrating to not know what the deal is.. but i guess as long as people know what to look out for.

also, i have an LS mc sitting in the garage that i just looked at, and its just like you said, the threaded hole on the passenger side of the mc is for the larger, 12 mm flare nut.. dumb ******* luck on my part with the gsr mc having both holes be 10mm!

importimage

supposedly the rubber material gasket between the mc and bb is faulty. From my research, I cannot just get the gasket, so I have to get a new one. Any suggestions?

tonyxcom

Sorry to revive an old thread, but I just wanted to clear something up.

My ABS MC came off of a 97 GSR. I took it off myself.

I didn't find out the fitting was larger until I got it all swapped in.

The hardline itself is the same size as everywhere else, but for some stupid reason the flare fitting is larger. A good 2mm larger.

It wasn't hard to reflare the line. I went to HAP and got the fitting I needed and also got some extra hardline to practice with.

DavidR

News flash.

94-97 Teg ABS M/C has the larger rear nut
98-01 Teg ABS M/C has the smaller rear nut

Nuff Said.

Edit: If you use a 98+ MC, you have to use a 98+ booster, and vice versa.

carsaregood

DavidR - Thanks for clearing that up!
