which 1" master is this?
it was on my racecar (eg) when i bought it and it needs replacing but i have no idea what its from.

blackGSRcoupe94

from the pics it looks like a 98+ integra RS

It's the early itr/mid production and integra one I'm staring at the late model itr one and the ports are different

98SpecR

Incorrect. Judging by the single port, this is definitely a pre-1997 master cylinder. If it is a 1" it must have come off something with ABS, possibly a 96 spec ITR if it's JDM. However, I would guess it's off a DA with ABS.

The later DC master cylinders and resovoirs were dual port: The RS (no ABS) had 15/16" MC and the rest (with ABS) had 1" MC, all of which were dual.

I have not looked in a few yrs when I replace mine, but I thought that the older, '94 type had the slanted back, at hookup to the booster, and newer were straight across, and the reservoir rectangular. A few vendors have made 1" MC for 94-96 tegs that fit the booster. I was able to physically look at them in various autoparts stores.

Round reservoir (1) older and (25) newer. Then abs or not.

ok, i found this on-line place that has the layout i need listed as 1996 integra w/o abs. they only have re-man units. im trying to get new from honda. http://www.autopart.com/brakeMasCyl/...URAINTEGRA.htm

if you look at the diagram on the acura site, the single port master doesn't have the lines in the locations i need. http://www.acuraoemparts.com/delray/...All&vinsrch=no

the DA master looks pretty close, but is 15/16ths. not 1". at least the non-abs one is

My "standard" was 15/16 and I got one at NAPA that was 1" for my '95. I could have gotten either size, after market, thru a few vendors, but not a 1" Honda one for my year.

with the lines in the orientation i need them in?
what model/year?

I have a '95 with ABS and my take offs are different. My front outlet is on the driver side and rear on the passenger side of the MC. Looks like an RS, or nonABS MC. I found pictures here

The last one on page one is the RS, nonABS one. I think that is what you are looking for. Once you determine that, then you can look at various brands, some aftermarkets are now 1" for the same booster mount. At least I could find either 15/16" or 1" in various non-Honda brands for the ABS MC.
Hope this helps.

My NAPA is 1" for ABS and I think that it is Beck Arnley. I found several, but it did not specify 1". Beck and Arnley is not reman, and I think 1", but you will have to confirm. 2 years ago, I could not get a 1" OEM Honda part with the diagnal mount, just the '98+.

i did some more research and it looks like its possibly from an early DC chassis RS but i'm not 100% yet.

Yep, nonABS is the RS.

That looks like a DA master

Also if you want to change em go with a 15/16th 90 Civic Sedan 1.6 model, The smaller 1.5 models have 13/16th and CRX si's have 7/8th
Judging by your pictures you don't want to bend lines or anything, 15/16th 90 Civic will work fine for you. Fastbrake sells em or you can go to Autozone and buy a reman 15/16 for $60.00.

When you start going to 1 inch masters you need to re flare the 10mm fitting to a 12mm. Depending on your brake setup 1 inch may be too much too.

Not true I have 1"mc with 10 fittings.

Lo-Buck EF

I know for EF stuff, the EX master or one of the older prelude masters (both 15/16ths) are the way to go. this is on an EG.

It could be a DA one. the DA non abs is the same master as the DC RS.

i was pretty sure this one was 1" which is why i'm having a hard time figuring out what its from.

The NAPA aftermarket 1" for my 95 did not require more flare and is made as a replacement. Unfortunately I could not find an RS, nonABS, 1". There are several brands and there may still be a 1", I just did not find it for the RS.

STN_Pat

both the fittings are 10mm, but are they both the same core size ?

90-93 GS 4 doors (or any ABS 90-93) are 1 inch, both fitting requires a 10mm key, but one fitting has a bigger core (its hole is bigger). They fit the 290V booster fine.

Lo-Buck EF

both fittings are 10mm but the rear one is larger core.

you know the guy who you got the car from might know a thing or two about hondas, and that car.

Lo-Buck EF

yea, hes just hard to get in touch with

Lo-Buck EF

90-93 teg w/ abs it is!

I saw somehwere on here that the '90 EX was the one to go with on EG's also

Lo-Buck EF

Ex master is a go with the stock booster and its 15/16ths.
I have the dc booster so the mounting offset is the opposite. Also, the da abs one is 1".
